Just got some Cocodan Croutons ($16/bag) to mix into Bioterra for my next grow. Haven't tried this mix before but I need to lighten the Bioterra up, too much water sits in it and makes my grows susceptible to fungus gnats. I'll still be mixing bat guano in at the bottom and worm castings in the middle and top. Hopeful this mix will be the one...
Im using straight BT in 5-7 gallon smart pots, some 10s. It's been a great medium, like has been said holds shittons of water. I noticed that the chart Canna gives you is kinda off. At least for me. Im like 4-5 weeks into flowering and I've had to step up to 2-3x the recommended max dosage of Bioflores. I'm also using about 20-25 ml bioboost a gallon. Looking like great results!
They also said 8-16 ml of bioflores, and my plants started having serious deficiencies using 16 ml a gallon. The chart from Canna says on the bottom for beginner guidelines only. I don't consider myself a beginner.
Just use boost for a foliar. 25ml boost 25ml bioboost to a gallon of ro water. You will get amazing results and save a lot of $$
I use Canna Terra Pro and I love it. I mix it with 40% perlite and a small bag of worm castings, there is only 1 problem with using a high peat moss based soil and that is fungus gnats. Just make sure you flush with Neem before planting and just before flowering and you will have gorgeously tastey, sticky herb.
Canna is also one of the only nutes to actually pass the label test. Practically zero quality control exists from other manufacturers. I have seen the tests with my own two eyeballs. I use bio-canna in b`cuzz soil. Black and green bag, slightly better than sunshine #4 in terms of the clay block effect when it gets too dry.
To the person about to use BioTerra out of the bag...please stop before you really F* your clones up. The water retention in this soil is way way way too good. I would suggest you cut it at least 50% with perlite or higromite or something. I have had burning issues when trying to transplant to it straight w/o watering, its wet enough out of the bag. I have had over-watering issues with every clone I have placed in anything increase in moisture at all out of the bag...BioCanna is heavy soil. You really need to be aware of this issue when dealing with the soil. Its like a mother effing ShamWow.
As it was explained to me, those fruit gnats are the top of culture train in your dirt. The gnats don't cause any harm to plants (although they are a nuisance) and removing them is removing the top of the food chain in the culture your trying to build with an organic setup.
, if you can accept the gnats, you want to leave them alone.
this is second hand knowledge though..
The gnat larvae live in the soil and eat your roots.
