OMG....100 gal? 200 gal? Seems to me that is a bit of overkill on the soil. How long do you grow them 6 months? I dont think the potted plants need any more than 10 gal pots, I usually use 5 gal for the last phase with a total growing/flowering time of 4 months or so. any longer than that and you are just spending money on nutes. JMHO.
