An interview with Biotabs. True life organic.

Growing organic Cannabis does not require a great deal of skill or maintainance, however more a case of the balance within the growing medium. Understanding the difference between organics and hydroponics goes much deeper, literally all the way down to molecular level within the soil. Weed World sat down with Kees Schelfhout from BioTabs to find out as much as possible about organics from a cultural point of view, as well as how it benefits the environment and Earth. 

Hi Kees, Thanks for sitting down with Weed World. Can you tell the readers about yourself and how BioTabs started? You’re welcome Weed World, BioTabs is an innovative Dutch Fertilizer brand founded by Karel Schelfhout. We started 6 years ago in a garage in The Hague. Now we are based in Barcelona in a big official warehouse. Biotabs work exclusively with living micro organisms, beneficial bacterias and concentrated compost. We look at mother nature and we are copying active soil life.

 What is meant by true life organics? There is a book written by ‘The Rev’ about organic growing, which is his way to describe organic gro-wing. Also check out the Bio Grow Book Written by founder of Biotabs (which is also full of tricks and organic tips). For me it means only working with raw natural elements because I believe in this way the highest quality can be reached with the best clean tasting smoke, and the most enjoyable smooth buzz. For example, our nutrient block is a compressed tablet made from different organic materials. This includes fish meal, bone powder, blood powder and many more elements and also contains various strains of different beneficial bacteria. The tablet will slowly release nutrients throughout the grow with the simple application of only water.

How would you explain hydrop- onic food to a beginner grower? With hydroponic growing you are feeding the plant with just a small number of basic elements, perhaps as little as 12 different minerals. These are always synthesized in a chemical factory. This results in one-sided feeding (limited choice) for the plant, and the plant may not be at full potential, it may not have the best resistance against pest and disease. An additional worry with chemical nutrients is the need to flush near harvest. When not properly flushed, your flowers may contain nasty mineral residues, with unknown long term effects, which is why at BioTabs we believe the plant is totally dependent on you. As we see now in the America, there are stringent levels of testing and standards of the hig-hest level when testing flowers and extracts.

How would you explain organics to a beginner grower? With organic growing, the grower only uses natural products such as beneficial bacterias, microorganisms, and compost . All created in an environmental friendly way by mother nature meaning the rich li-ving environment of natural soil is constantly active. The bacteria and microorganisms break down the organic material (compost). The bacteria action ensures that the nutrients are in a form where they are easily and naturally absorbed by the plant. The bacteria are cre-ating the nutrients on the spot in a natural and organic way, which the plant can readily absorb. Supplying mineral chemical nutrients from a chemical factory isn’t necessary and therefore with Biotabs products, chemical free flowers is guaranteed. When orga-nic growing, it’s important to keep the soil moist and prevent it from drying out and killing the living soil. The bacteria stick to the soil particles and ensure that the nutrients are produced. Some bacteria are eaten by other bacteria, this is all part of the natural living soil biosystem. Keep the growing medium moist and environmentally friendly for the beneficial microorganisms! 

The plants are so smart that the roots will produce certain sugars to feed the desired type of bacteria.

Could you explain how bacteria interact with plants? This is actually where the plants show their superiority when grown organically. The plants are so smart that the roots will produce certain sugars to feed the desired type of bacteria. When in the vegetative state the plant needs Nitrogen for growth. The sugars produced by the roots will attract bacteria that are able to produce (or ‘fix’) Nitro-gen in a form which is easy absor-bed by the plant roots.

Later on, when the plants are in bloom and need more Potassium, the roots will produce a sugar that attracts bacteria that are able to produce Potassium in an easily ab-sorbed natural form for the plant. Which means when you grow organic, you have a self sustaining plant. (Don’t panic, it is organic

Is there such a thing as bad bacteria? Yes there are loads of bad bacte-ria (pathogens) which you need to keep out of your soil. The best way to support this is by working as cleanly as possible, and in the soil making sure there are plenty of Trichoderma bacteria present. The Trichoderma will colonise the ‘rhizosphere’ which is the upper 5/10 cm of the soil, where the feeding frenzy takes place on a bac-terial scale. Trichoderma are so big in size that it becomes hard for pathogens to colonize the rhizosphere. pathogens to colonize the rhizosphere. Make sure you keep topping up on the trichoderma, to ensure it all stays colonised is key.

The root zone does not have to put much energy to protect itself against pathogens, more energy is left to uptake nutrients and sti-mulate the entire plant growth. A good tip is to make sure you keep topping up on the Trichoderma, to ensure it all stays colonised as the Trichoderma will perform well on any substrate such as coco or soil. Another beneficial quality of the Trichoderma is that it will stay active in temperatures from 5 -35 degrees celsius, where as other bacteria die or become inactive when the soil is not in perfect condition for them. 

We use a mix of 9 different mycorrhizal fungi,
which are actually spores.

What tips to you have for maintaining consistent temperatures both in the water and room temperature when hash making? Fungi are great! The fungi we like to work with when growing organic is the mycorrhizal fungi which is our product Mycotrex. We use a mix of 9 different mycorrhizal fungi, which are actually spores. When these spores germinate they will look for a root, when they have found a root they will start a symbiosis, that means the roots and the fungi are starting collaboration in which they both enjoy benefits. The fungi feeds on the sugars produced by the roots and the roots get nutrients from the mycorrhizal fungi. Big roots mean big fruits is the expression and it all starts with the roots zone.

How can a farmer with mineral deficiency improve the sustaina-bility of their land with the use of organics? Farmer could totally revitalize his land with the use of organic growing, and there are many methods for this. One of my personal favou-rites is by using plants. There is a special variety of grass called sudan grass and after a big harvest farmers like to grow this, it will grow incredibly fast. When it has reached a height of 1-2 metres in height the farmers spread some compost and bacteria on the land, and then will cut the grass and leave it on the field to compost and become part of the natural life cycle. After the grass is composted, then the soil is ready to rock.

Could you explain the differences between hard foods and liquid foods, also how do plants buffer them? Hard foods can be thought of as similar to compost. They may be supplied in powder form and their structure and nutrient value break down slowly and will keep on releasing nutrients throughout the grow, making these a great base for your living soil. Liquid foods are the liquid, fluid and syrup such as molasses style materials used in grows.

In the Biotabs strategy you can adjust and boost the soil by adding the Orgatrex when needed which is our version of a liquid compost feed. Burning or overfeeding is difficult when using hard or soft foods and a reason why organic growing is so user friendly and forgiving.

Can you tell us about the culture of true life organics in Europe from your experience? It is growing for sure, more and more people start to see, feel and taste the benefits of organic gro-wing. However, as you know growers are one of the most stubborn people out there, that’s why we chose our life style. There are loads of ‘chem’ growers as I like to call them, and they think that they have invented the wheel and don’t want to change a winning chemical formula. It will take a while before everybody has switched over, yet is just a matter of time before humanity will come to its senses. It won’t be cool to grow with minerals anymore, or it will get forbidden in the future I believe.

How important is correct pH and E.C when growing organically? They are super important as the beauty of organic growing is that when the right bacteria and microorganisms are present in the soil, they will take care of pH. When using the BIOtabs range, measurement of pH or E.C is simply not required! Just as in the forest, never has anybody been seen adjusting the pH or E.C of the rain that is falling. Nature is so simple and the soil life will provide.

What are the different organic substrates BioTabs produce and how environmentally friendly are they? We have 10 different products all created out of micro organisms, bacteria and compost. The main working organisms and nutrients are mycorrhizal fungi Trichoderma, molasses, silicium, guano, spore elements, rock dusts, algae and insect manure. We chose these products because they are all natural and environmentally friendly. For example our Silicium Flash is made from a certain meal worm manure. These mealworms are bred to feed the chicken a well deserved natural meal. Chickens fed a natural healthy diet won’t need antibiotics, making the chicken cleaner to eat. The mealworms are fed with the leftover/ unsaleable fruits and vegetables from the market. The manure of the mealworms is used as an organic material to enrich our soil and feed the plants. In this way nothing goes to waste and it’s a nice organic circle and true life organics in action.

“Don’t worry boy, they only will get bigger and there is nothing you can do about it.”

Are there any bad substates that growers should avoid and why? In my opinion growing on rockwool is not great, because the minerals that are used when growing in rock-wool can contain/ burn mother soil with salt, minerals and heavy metals. Rockwool is impossible for nature to compost and where I used to live in Holland, there was a large open space, used for farmers who needed to get rid of all the rock-wool cubes used for growing tomatoes and cucumber. Suddenly this place was filled with huge white, plastic rock-wool mountains. When asking the local farmers what the plan was with these mountains of rock-wool, the farmer simply laughed and said “Don’t worry boy, they only will get bigger and there is nothing you can do about it“.

How do compost teas work and what it is that is actually being brewed? Compost tea is brewing your own compost using the same principle as the soil, but with a tea there is a much faster growth rate of bacteria and microorganisms present. Our bacteria will multiply much faster in water when they are fed with oxygen and some sugars; in the case of Biotabs Orgatrex, they will explode in terms of growth.

After 24-36 hours your brew will be filled with billions of beneficial hungry bacteria and Trichoderma. Add this brew to your soil and the cocktail of hungry bacteria will devour the organic material and other increase the activity of beneficial microorganisms that are already present in the soil. Leaving the soil full of nutrient rich bacteria manure substrate allowing the plant to easily digest and increase plant health, biomass, resin and overall stench.

o you have advice for growers dealing with plant disease ind-oors such as mildew or mould? The best thing you can do is work as cleanly as possible. Make clones from regular seed plants, re-fuse dirty clones from your friends no matter how good the strain may be. Make sure your conditions are as optimised as possible and If you have multiple grow rooms or tents, then always check the ‘clean’ mother room first then check out your big flower room.

There is a higher chance of a little insects or spores of mold in the big flower room than inside the clean mother room. Don’t check out your mother room again after you have been in you flower room, otherwise you may bring the bad stuff in. Here in Spain, there are massive mildew problems, so at Biotabs we have all our air inlets hooked up with a U.V cleaning light and an O-Zone machine to kill the spores, which works very well. Finally…What are BioTabs top tips for anyone who wants to get invol-ved with true life organics and whe-re can our readers follow you on social media? Just take it easy. Never forget to enjoy growing, and try to create an enjoyable hobby from your work. Grow a tree and feel free!

An interview with Ex-Tractor. Specialists in organic solventless

Harvesting trichomes and producing top quality, organic full melt hash seems to be an ever growing craze in the States. Soft Secrets sat down with Kees Schelfhout from EX-Tractor, a dutch extractor based in Barcelona who specializes in organic and non solvent. We find out more about hash making, different techniques, terpenes, freeze drying, the hash culture in Amsterdam and Europe and what his top tips are for any purveyors of the finest full melt.

SSUK: Can you tell us more about EX-Tractor and how you got involved with Cannabis? I was fortunate to come out of a family that; eats, sleeps, drinks and breath growing plants. My Dad Karel Schelfhout was one of the first to cultivate our beloved plant indoors back in the day. He started the Super Sativa Seed Club in 1985. I also have a brother that got into growing on a young age as well, and he developed a strong talent for pushing the boundaries on increasing the yields when growing organic and setting the standard high, for what we consider a high quality smoke.

Those two guys are my mentors and our mother Liliana has always supported us, and encouraged us to do it better, cleaner and worry free. Out of love, it is natural to explore the different possibilities of what we are able to do with a plant. Besides the growing, a couple of years ago I really fell in love with iceolator technique. Then Ex-Tractor was born.

Can you explain what EX-tractor specialise in? We like to keep ourselves busy, only with clean organic solventless extracts. In essence we are washing and sifting most of the time and during our trimming we always work above a huge, 1.5x 1M sized 110 micron screen where we collect loads of dry sift trichomes.This technique I learned from my father, when I started rolling in to the weed scene. Our favorite way of mining our beloved trichomes, is the Ice water hash style or iceolator.

I started making small batches of iceolator in my student kitchen 7 years ago, and was amazed by the various qualities and quantities that could be reached, when using this technique.In love with the pure smoke and the intense high you can feel, that for real will give you a different perspective to life. Then a whole new world opened for us when the dry freezer was introduced to the party. Now the hash became even cleaner, due to super short drying time, meaning that we won’t give

With the classic dry method you could give mold a chance to develop in the soggy moist hash. We are now dipping our toes in to Rosin pressing and have to say it is loads of fun, trying out different temperatures, pressures and micron sizes. Discovering interesting, changes of structure, smell and colour. At the moment we are most pleased, with the soft golden butter structure squishing can produce.

Which strains do you personally work with as official hash maker for The Super Sativa Seed Club? The Karels Haze is one of my favorite strains to make hash from. My dad and me have been working on that strain for a couple of years now which is Old School Haze X Chem Dog X OG Fire. The terps on this lady are just all over the place and your nose will be welcomed with fresh citrus notes combined with a gassy, fuel aroma with a background of Haze mixed in. The trichomes are bit dark gold coloured and are quite big in size for a haze cross and the Karels Haze gives good returns and she also packs a real punch with strong flavour ratio. My other favorite is the for me recently discovered Cookies N Cream from Exotic Genetics. The first time we grew it, immediately was visible that the trichomes on this lady, are present in abundance, big sized and the most beautiful golden colour I have seen on trichomes so far, combined with a very creamy smoke and a chill relax buzz..

What are your techniques when it comes to washing the buds and trim? We like to dry out plants for 7=9 days before we start trimming and storing the trim and small bud in the freez-er. Then we are sure all the chlorophyll is dried out and no funky green taste is left in the hash. In your washing bag there should be only small sized buds present and trichome rich leaves. Since we live in Spain and the water has very poor quality, at EX-Tractor we work with clean reverse osmosis water. We like to pour a bag of ice cubes inside of the washing bag, so the leave material has more contact with the ice cubes and trichomes can break off easier. We start with short washes around 1-2 minutes and collect the hash. Then give the hash a little extra wash inside the collection bag with a plant sprayer filled with clean water. We do not use one where nutrients were in before making sure it is clean and sterile. The second wash will use new water and some extra ice cubes. The washing time after each collection of hash will become longer until a washing session of 5-6 batches are run. Then the hash will be popped in to the dry freezer to get the hash dry in 14- 24 hours depends on how full the dry freezer is

Do you have a preference to micron size when washing your materials, and which micron grades do you consider inferior? With most strains the 73 miron will contain the most trichome heads. Although have some Sativas our Old School Haze and Mango Haze, that can fill up the 45 # micron mesh pretty good due to smaller size trichome heads. The 220 and the 160 micron is really for only separating the bad stuff from the good stuff, Some say that quality is great for cooking, but I rather use high quality grade for cooking also.

The first time I saw quality hash coming out of the dry freezer was so intrigued that I needed to know more!

You dry freeze your hash but can you explain exactly what that means for those who may not know? The first time I saw quality hash coming out of the dry freezer was so intrigued that I needed to know more! All of a sudden this hash became gold, why does it stay gold, why does it smell so intense? The dry freezer was the secret behind al off this so I ordered one right away and started freaking out at what this device does: It will first freeze the hash all the way to its core. All the water in the hash should be turned in to ice crystals, so first you have to figure out when that point is reached depending on how much freeze time.

Then you have to know that H20 has 3 stages, firstly ice form, then the liquid form and then a gas form. The machine freez-es the hash, and after the hash is frozen and the vacuum is pulled. The ice crystals due to the vacuum don’t turn in to water first, they immediately will turn in to gas. This process is called sublimation. During the sublimation process, the hash will start to dry as the ice crystals evaporate immediately and only the essential oils and terpenes will be left in the hash.

Therefore the hash is in minimum contact with air, water and light meaning no chance for oxidation, and will be filled with all the original flavours and terpenes. That is why the hash has such a superior taste. What is also a big benefit of the dry freezer, if you plant material contained some mold or bits powdery mildew, then during the freezing process these will be killed.

What tips to you have for maintaining con-sistent temperatures both in the water and room temperature when hash making? This is actually funny as I personally learned about this the hard way. In Holland it is always quite cold and dry, so the room where would make ice in the temp was pretty constant all the time. This was easy to maintain the same temp in the water, due to the room temp being stable. After moving to Spain and starting to make ice for the first time, we notice that the relative humidity and temperature is always a lot higher here. We lost a small batch to the damp moistyness over here dur-ing our first runs, which was way before the dry freezer days of course. Now we work in a nicely sealed room, with a A.C providing us with a fresh cool breeze, making sure the temp stays the same all the time, and giving moist not a chance.

I make my temple balls out of dry frozen iceolator of a mix of different micron meshes, in order to achieve that full spectrum experience.

Can you explain step by step how you press your temple balls? I make my temple balls out of dry frozen iceolator of a mix of different micron meshes, in order to achieve that full spectrum experience. I will grab a tray and throw in 3 grams of 73 micron hash, 2 grams of 45 micron hash, 1 gram of 90 micron hash, and 1 gram of 120 micron hash. Next I will mix it up and then add some more 73 micron to get the quality more creamy and extra sticky. We will put a gram in our hand palm and start working it with our thumb and rolling it all together, once it is a nice ball start rolling it on a hard clean surface, on top of baking paper works best. Once the ball starts to shine, she is ready for packing, storing and curing and that is the basics of making a temple ball!

A larged sized temple ball being made

How do you ensure the materials you are using are totally organic? We are very conscious about the equipment and prod-ucts we use, as they need to be of a high standard, that makes us able to make such a high quality hash. High Quality product in simply means a high quality product out. Only working with the best products out there and how you are feeding the growing medium in the end will decide if the hash is residue free.

Ex-Tractor grow all our plants 100% organic on the BioTabs organic range. This is a organic strategy that only works living microorganisms, beneficial bacteria and concentrated compost. For lights our standaard was the Gavitas 1000 Watt, but now we are mixing this light SANlight LED and we are providing a much wider spectrum to the plants, and it is stimulation the trichome production significantly.

Ex-Tractor grow all our plants 100% organic on the BioTabs organic range.

Has EX-Tractor won any awards for your hash making? I have recently entered in one competition which was at the Homegrown Cup in Holland. This is a cup only the competing growers are able to judge the rest of the competition which is how I feel is the most fairest way of judging a cannabis cup. EX-Tractor took home the 1st Place in the NederHash / icolator category. Our entry was a super short cold wash of the Karels Haze for just 1,5 min long and only handed in the 73 Micron quality. Happy days and we cannot wait until next year!

For those visiting Barcelona, where can they expect to find your work? Most of my work is to be found in the Nectar Club who I have been supporting my work right from the start, and are very cool people. In La Kalada some times you can find little bits there also at Dr Dou and the Resin club is where most of our products can be found.

Finally… Where can our readers find out more about EX-Tractor on social media? We are active on Instagram under @ex.tractor where you can see my work and give me a follow. Thank you and keep up the great work Soft Secrets and Stoney, and green greetings to all from Ex.tractor!
