The smallest pots I use to finish plants in is 7 inches square, about 3/4 of a gallon. My fast indicas (from clone) will veg 3-4 weeks and flower 6-7 weeks. So I go from clone dome to harvest in 10-11 weeks. Growing in small pots forces the plant to flower earlier and finish quicker. My MJ guru tells me that a good rule of thumb is to use one gallon of dirt for every month you plan on keeping the plant. By using the smaller pots I am forcing the plant to mature earlier. BigSteve.
