hey AL I HAVE FOR A QUESTION! The trimming you speak of in the 2nd and 3rd weeks. Could you elaborate on this matter as I am very curious. You are putting them straight into flowering so exactly how much of the lower part of the plant do you remove and doesnt this late trimming affect overall yield? Sry if you already answered this, I have scanned many pages of your thread and am very impressed, however missed this issue.
You're looking to remove any branch which gets more than about an inch long, from the lower 1/3 of the plant. It takes a couple of passes at pruning, hence my advice to prune in wks 2 & 3. The lower branches produce poorly and restrict air circ around the plant in a SoG op.
The per-plant yield is naturally lower compared to unpruned plants, but I can fit ~6-8 SoG pruned plants in the space occupied by one unpruned plant- and all the buds I get are big, fat, heavy, sticky tops, no time-wasting, hard-to-manicure 'popcorn' buds from lower branches.
Mind, you won't want to use the SoG pruning strategy if you're only growing a very few plants. SoG is all about filling a lighted space with as many top colas as you can pack in. This is done by growing a greater number of smaller plants.
SoG has a real legal drawback given that it depends on high plant numbers, but the quality improvement and ease of manicuring large top buds is attractive.
the thing is that i in my grow area the humidty gets down 2 about 30 and everthing dries up real fast with the 1000wat hps its in a small grow area. and i actually noticed the they were 3in rockwell cubes.
It's a far greater sin to have excessively high humidity than excessively low. I've never lost a plant to low RH but have lost plenty to bud mould and other problems. 30-50% is ideal, but if RH does wander lower, don't fret.
About the only problem I can think of made worse by low RH is spider mites. Simple- don't bring mites in. Wear clean clothes, make sure the soles of your shoes are clean and avoid contact with any outdoor plants before entering your op.
