Im gonna be using 550 watts of hps per lab in 2 grow labs with 98%+ reflective material (AWESOME BTW) growing La Diva, Pandora, Afghan Kush Ryder and Easy Ryder. Im gonna be using roots ogranic soil, earth worm castings, blood meal, fish bone meal, dolomite lime, perite, epsom salt, humic acid, and azomite. I put the mix in a trash can, add water and let it cook in the sun for 30 days to activate the mycros. I use no nutrients just ph balanced h20 from start to finish. Never plant seeds or clones directly into this mix! This is a hot soil mix so i only use 30% to 50% of this "Super Soil" and the rest just plain roots soil so that way the plants can work there way into the hot soil. This is gonna be my first run using these methods. I got the soil base recipe from Subcool who is certainly the most respected grower in my book! He's the top dog of "TGA Subcool" seed bank and breeding co. Go to the Attitude Seedbank and check out his stuff!! I'm all about learning from the best and spreading these supierior methods like wild fire so if your serious about your stuff and want the most best tasting buds, hydro like growth, aromas and super monster terpins...Go under the organics forum and look under Subcool's old school organics. There you will find the 2010 revised super soil recipe. Happy grows and sends me your thoughts on this!! ONE LOVE!!!!
