Ok so I will lollipop and clip the top stretch off . For the record this room NEVER had air flow problems mold bugs etc. That ALL came with clones.
I have them very tight cause that's all that this light lets me do. My bloom room is 4x4 and 1000 watts HPS. I will de leaf a lot to allow proper air flow.
I did 7 in my tent last time and I had a huge fan take up room I now have powerful clip on fans so I'm sure 8 will fit but not without a lot of trimming.
If it doesn't work out it will have to kill a plant like you guys suggested.
Thanks for your input will post pics soon
