I apologize for posting pics without much explanation. Pretty much all the pics I've posted so far are from veg. I let these things have an extended veg phase while I learned what to and not to do. I was left with 2 healthy females that I flowered. This is where these pics start. This is early July at the beginning of week 2 of flowering.
I killed the males and transplanted the 2 females to larger pots. I used 13" plastic pots. I used some MG w/ perlite for veg w/ nutes for veg. Mistake. On transplant I put about 1" of loose gravel at the bottom. Used some basic garden soil for that. I mixed in a good dose of bone meal too. For nutes I used some MG liquid plant food 8-7-6. Later in flower I started MG bloom booster 15-30-15.
Note how I've clipped the lights along the edge of the rubbermaid. I spent alot of time balancing them as their combined weight would deform the rubbermaid. Also note how I've placed the CFL's. THIS IS ABSOLUTELY CRITICAL. Too close and you burn, too far and lose lighting efficiency.
One of the first flowers forming. For the first several days of flowering the number of hairs would literally double every 12 hours cycle.
Also note the attemt at using the clip on reflectors. I got some tin snips and cut a few reflectors. They trapped a lot of heat and were very heavy. They upset the balance of the lights and the rubbermaid so much I stopped using them. My closet was already painted flat white so I already had the best surface possible.
7/19 start of week 3 flowering:
At this point you will see the problem developing that I will solve in upcoming pictures. They are growing too much above the lights. They got really confused and it stunted their vertical growth some.
Note how I am placing the 2700k's and the 5600k's to distribute wavelength and lumens, not only in this pic but any like it. I also took into consideration the walls and the shape of the plant to try to wring out every bit of efficiency from the cfls. I have somewhere north of 22000 lumens here.
Early in the grow I bought a basic shop light that I planned to use for the grow light. I dumped that in favor of the cfls. As the girls got too tall in the above pics they got confused as the strogest light gradient and gravity were about 90 degrees apart, not 180. I went back and got the shop light out of storage and hung it in the closet above the rubbermaid. I put 2 40 watt daylight bulbs in it.
Start of week 4 of flowering:
I spaced the lights out to distribute the lumens and wavelength as I wanted. I also had to take into account the balance of the shop light. Every adjustment in one place required another adjustments somewhere else.
You can see the fan I used here. I used some scrap plastic from my earlier plantars to make a shelf where I put the fan. It had to be aimed correctly to move air in the right places. CFL's are not hot individually, but they are in aggregate.
