oh,and forgot to mention this but it's for later grows not this one,you really should do organic grows,make it taste much better and who the hell wants to smoke ferts eh?but alas the organic growing is dieing out,being taken over by comercial grows pumping their plants full of fert to get the highest yeild possable,but they dont realize the consumer wants good clean clear smoke,but then they make money either way...but in my opinion(and in most growers,well the ones that have used it anyway)organic growing is much better in the end,and also,when kind of yeild are you expecting? 2-3 ounces each?
