Oh and I grow organic so to answer your questions...not familiar with those type of nutrients. I use compost/sheep shit mixed with high grade organic soil. Then I supplement with liquid organic fertilizers, seaweed etc...as for pots, I grow seedlings in organic mesh pots about the size of a small cup. These pots break down when planted in larger pots or the ground. This way I am not really transplanting because I never take the plant out of its container...the container just breaks down. I plant one hundred at a time this and then thin them out to 50 as time goes on depending on their rate of growth and health. The 50 theoretically turn to 25 once females have been chosen. This is probably not a choice way as you buy you seeds and every one counts...I only buy once a year for breeding stock and have seeds of plenty from doing this for a few years. ANYWAY, organic or not...break down seedling pots are the bomb. Good luck
