Whats goin on der buddy, long time no see! I been busy as hell lately and tryin ta keep my grow together and update my journal have been takin up a lot of my free time. Things are lookin very nice tho my man, its lookin like youre gonna have one helluva harvest! How many days you got left anyway???
I saw your question on my other thread and to answer your question Im runnin 32 in a 2x4. I actually had to remove one cuz it was slightly blocking my overflow valve and causing my table to drain slowly which unfortunately caused somewhat of a flood in my bedroom! So now Im down to 31 and Im considering removing another one thats much smaller than the others and is having a really hard time getting any light. So I might remove him to make some room for the others, you should see my table man its like a freakin jungle!
But if you wanna increase yield (who doesnt) you should try running a high number of small plants. The first time I tried it I got 3 times the yield of my previous run and the only thing I changed was the number of plants, same nutes, same space, same light, etc. 32 is a good number for a 2x4 as long as you flower them small and run single top plants. I vegged my too long and made the mistake of trimming the canopy to even it out. This Choc pheno branches like crazy if topped even once so I ended up with 31 18" branchy ass little monsters! But I did some serious surgeory to thin them out and clear out the bottom third of the growth to increase airflow and everythings goin good. Theyre still pretty crammed in there but I have high hopes for yield this time around. I watched Seemorebuds Vol 1 and he does a set of 2x4 tables w/32 in each and they look identical to mine except he didnt thin them out which led to early harvest due to mold. But he still yielded almost 2 lbs per table and claimed it wouldve been even better if he did some trimming and didnt have to harvest early. So if I do half as good as he did Ill be very pleased! But I would try 32 or maybe even 21, 3 rows of 7 or 6 would give you more room ta work with. I think this method yields so well because every single bud is directly under your lamps and is able to get maximum amounts of light throughout the cycle. With taller plants the lower buds dont perform as well, and alot of your space is taken up by big branches and lots of foliage. With SOG you basically have a bunch of buds on a stick w/no wasted space! I love it!
