my own personal experience....

I took 10 clones from 1 momma.....
5 where in 1 gallon pots about 10" across
5 where in 2 gallon pots about 12" across

all plants started in these containers.....
all plants grew for 8 weeks in the veg. state.....
in DID NOT trim any of the plants, I figured this time for this experiment I wouldn't trim them at all just wanted to be able to compare the 2 growing conditions, which were identical other than the containers.....

Plants in 10" 1 gallon containers were 3 feet tall after 8 weeks of vegging
Plants in 12" 2 gallon containers were almost 4 feet tall with 2/3's more nodes per plants

After 10 weeks of flowering.........

Plants in 10" 1 gallon containers were 4.5 feet tall
Plants in 12" 2 gallon containers were 6 FEET TALL!!!!!

Yield from EACH PLANT AFTER PROPER DRYING:

10" pots: average 5.5 oz EACH PLANT
12" pots: average 9 oz. EACH PLANT


I shit you all not fellas, I WILL NEVER GROW in anything other than 2 gallon containers that are no larger than the canopy of the plant, meaning if the plant has a diameter of 12 inches across the roots can grow in a container that is 12 inches across. When I have grown in 5 gallon buckets, I have had NO SUBSTANTIAL improvement in yield over a 2 gallon container. 2 gallons 5 gallons, its been my experience that the strain i have been growing show no substantial improvement.

I am in no way an expert, but these are only my personal observations because like many others i was bored and wanted to know the answer, so I figured "what the hell, why not do a little experiment"
