Indica hybrids generally stretch to 1.5 times where you budd it from in total hight. 2.5 times for hybrid Sativas. You can expect that the HI will grow vigorouse earlier but the HS will grow taller over the total period.
*If the total hight is 2.5' in a grow box: (30" is the total. HI should budd no latter than at 20" and HS budding no later than 15").
That's a small box...my 6'x6'x2' is a good example. If 6' = 72" and is my total height...this means, (after leaving space for lights and fans), that my Hybrid indicas must budd no latter than 40" and hybrid sativas no later than 30"). Watch the size of pot. This helps with the size of the plant control.
*In two of these 6'x6'x2' boxes I grow 8 smaller plants three feet each and get 1oz off each in 4 months total. (Soil, 3 gallon, SOG). My cloning system takes 3 wks, they veg for another 3 wks, then budd for 8 wks. Sometimes I top next time I won't.
The outdoors gardening is in a frozen predicament at the moment so I must grow inside and entertain myself somehow right?
