what are ur absolute best chances for growing two to two point five grams per watt with a soil grow? do not calculate my watts...they are irrelevant. whats the strategy? is it veg time? the size of the finish container? genetics? light movers? the grower himeself of course plays a part, yes, but given big bud crosses, money, time, creativity, patience, how could one gain the most? im not thinking hydro. not yet.
