    Have anyone tried growing low pressure aeroponics with dutch bucket setup instead of tubes? Would 11 litre bucket be enough?

    Candy or cookie recipe with predictable THC content?

    I usually make BHO from my harvest and have made gummy bears and capsules from the BHO in the past. This time I will use the buds for edibles. This batch is for a friend who needs it for pain relief. So I am looking for something that taste good with a predictable THC content. Perhaps start with...

    Shatter from winterised BHO - realistic?

    Usually I have no problems to get shatter from BHO. I have done some experimenting on winterizing to get a more "healthy" medicine. I dissolve the BHO in 100% anhydrous ethanol. After freezing, a reasonable amount of wax gunk is extracted from the BHO. The ethanol is evaporated at 33C (91...

    Best strategy to combat stretch problem in a 4x4 tent

    I have started a grow from seeds with a new strain (Jack Herer). The purpose was to find a new motherplant so I vegged them long enough to take a couple of clones from each one. Six of them turned out to be females. The grow space is a 4x4 tent. Lightsystem is cooltubes, 2x600 watt HPS. Today is...

    LEDs vs HPS - quality of extracts

    I use HPS for bloom. Problem is that my grow room gets too hot during the summer months. I have considered an AC unit but unfortunately it would add too many amps. So far, I have closed down the grow during the summer. My interest is focused on extracts. I make extracts of the entire harvest...

    Safe to store coconut oil & BHO in a syringe?

    I decarboxylated BHO in cocounut oil and collected the product in a syringe. The black part in the end of the plunger that seals the barrel is made of rubber or silicone. I need to know if coconut oil dissolves the black part. Is it safe to store the product in a plastic syringe?

    Does extracts give the most consistent effect with edibles?

    I have tried cannabis infused food in the past. The effect varied from short duration with subtle effect to long lasting with strong and almost paralyzing high. I abandoned the idea, until recently when I read the chloroform extraction thread...

    Can anyone have their extracts tested for purity?

    Occasionally I read about people on RIU that have their extracts tested for purity or for residual solvents. Are there companies willing to perform tests of material that are sent to them from outside legal states or is it only possible if I am a licensed grower inside USA? Im not a US citizen...

    High quality product from older material?

    A friend of mine seldom use cannabis but is almost addicted to grow. He is about to move in with his new girlfriend and offers me his harvest at a most reasonable price. No trims, buds only. Problem is that it has been stored for almost 1.5 years. It has been stored in mylarbags at a...

    Short path distillation vs butane extraction or QWET?

    I have a question about short path distillation. Perhaps it´s a really stupid question, if so I apologize: The equipment for short path distillation process is expensive and I understand that you need certain skills in order to produce a clean high quality extract. If you fail, the extract...

    Freeze dry before extraction?

    I have found a freeze dryer for home use. Still a little bit to expensive for me, but I hope the price will drop in within the next few years making them more affordable. Would freeze dried fresh non cured buds be good starting material for BHO and QWET-extractions?

    Laboratory vaccum desiccator for hexane and alcohols?

    I’m going to buy a purge chamber. Some of the companies selling vacuum chambers advice against using them to purge hexane and alcohols. I sometimes extract with hexane so I consider buying a laboratory desiccator made of glass. Those are relatively expensive but can handle any solvent. I read...

    Fire safety during extraction - Heating mantle vs hot plate?

    Finally, I have bought a lab glassware kit. I will use it for QWET extractions with ethanol and also extractions with N-hexane. I have a distillation apparatus to reclaim the solvents. My biggest concern is the safety. Heating mantle looks far more easy to handle but less heat stable than oil...

    Need to harvest early - what potency can I expect?

    A technician needs access to my grow area for a service job within the next 14 days. I have to finish my grow op early. Today it’s 51 days since I changed the light cycle to 12-12. I observed the buds with a pocket microscope. There are no clear trichomes left. Most of them have a milky pale...

    How to choose distillation column

    I need a distillation system for solvent recovery (ethanol and possibly hexane) and for distillation of alcohol for QWET. Being a non chemist I'm not sure what to buy. My guess is that a fractional condensor would give better quality but also need longer time and consume more energy to process...

    Fans during the last part of flowering

    After a minor mold issue I installed 2 oscillating fans in my grow tent. It works fine but some of the top leaves dries during the last 3-4 weeks of flowering. The fans works on lowest speed 24/7. The RH inside the tent is 53-59% It looks like this harvest will be the highest yielding so far...

    Users of Automatic ph controller - increased yield?

    Some strains are more sensitive to PH. I have noticed that the growth often is increased a few days after I correct the PH. I estimate that I let the PH drift to far a few times during each grow and those days quickly adds up to a noticeable percent of the total grow cycle. Question is if an...

    Any legal use and excuse for terp extractors?

    I have searched the web for companies/websites within EU that sells extractors like the MKIII or similar. I can´t find any sellers of this kind of extractors, or similar, within europe. I'm not sure of the legal status of terp extractors and therefore I'm not sure if it's possible to order...

    Replacing my drip system. Which way to go?

    I am going to replace my drip system with a new system. I love my old drip system but I would like to get rid of as much grow media as possible. My grow tent is 150 x 150 cm and I grow vertical for the moment (2 x 600 watt). HPA and RDWC both look very interesting. I have a green thumb but...

    Is it a bad idea: Aero or DWC + vertical grow?

    I have been growing vertical for about a year and it works fine with the limited grow space of my tent. I use a recirculating drip system with coco as grow medium. I read this thread on Amazon aero system from Nutriculture...
