Hey Sunny, I looked back a few pages to see what wattages your running over that plant???....didnt see it anywhere...you mentioning the limited height space, and it made me wonder what your lights are putting out....Tell you what, they get MUCH better coverage with those 2 bulbs as opposed to 1 with equal wattage...light coming from 2 different source locations, makes the light hit them from more angles...a bud behind a large shade leaf with a single bulb, is ALWAYS in the shade of that leaf....Thats the wonderful thing about light movers, OR, multiple bulbs if a mover just isn't practical for someone's space...add a little defoliation, and all potential budding sites are hit with good light....I am a BIG FAN of micro gardens...I did all of my nerve racking LARGE (Multiple bedroom) when I was younger...now I just kick back and find ways to maximize my little 4ft by 5ft closet...I found that everytime I expanded, the yield per sq.footage went down...the more I expanded the smaller that number got...LOL...Maybe with a LARGE grow, every plant didnt get as much TLC as they would in a micro grow......It is fun to challange every crop with your next one....I always considered doing my closet with 1 plant in a scrog set up, but the walls block access to the sides and far end....otherwise, I would have tried it...tents are a perfect chamber for accessing a scrog crop.....nothing more beautiful than a 600w 4ft by 4ft SCROG (done properly) with 1 plant....this link has a Berry Bomb grow with 1 plant.... I return to it offen for a little scratch and sniff.....Perfectly executed single plant scrog....early pics of it, remind me of your plant...
