This is awesome. I'm high as a fucking kite and I feel like I just watched a really good sitcom. If you are just going to let the plant essentially go to waste because of poor lighting, why don't you just let it go to waste because it sat outside? You are asking about an HID light in a PC case, let me tell you. I started my first grow two weeks ago. With 3 plants that I acquired from a feller; I placed them in my fancy grow box PC case with three 26w 6,500k CFLs. Well the one died after day two. Boo hoo. I still have two. Seemed to be doing great. This is also with soil that cost 1.36 from home depot. I was so happy. Well I placed a thermometer in there after day 6 when they were all dead, it was 103degrees in there. This is with the PC intake fan and PC exhaust fan. I was fucking blown away. I have since tried a fish tank type box which was successful for three minutes until it also got to 99 degrees. Then I said fuck it and made my stealth box. It's a subwoofer box that I belt. Big 12" sub on the front, 6inches deep. 20 inches high and 20 inches wide. So 6x20x20 then after that it goes to 14" deep. So, 14x20x20. Three CFLs wireless thermometer. 2 PC fans. Xbox 360 fan set. (dual fans) and a 4" house fan. The dual fans are used on the intake. Then the two PC fans are exhausts up top and the 4" sits next to the plants but flows away from them. This keeps air moving over them but not blown at them. Currently with two out of the three CFLs are on, oh I also added a 4th socket. But two lights are on and it's at 90.5 degrees. It's still too hot for me. The best part is, I looked at the pot that one of three OG plants was in and I saw a seed had sprouted and found another one that had germinated. The one that sprouted is doing very well. It's new leaves are coming in fast. This box is 3 days old now. I have germinated 6 addition bag seeds. I will pick 2-3 females and use all 4 6,500 26w lights after I get the box temp dwon to low 80s. I am leaving for FL for a week to pick up my girl and no one will be here to monitor the box. So I am trying to figure something out haha. Good luck with your 7ft tall plant. I am really fucking high and my mac n cheese just finished cooking. toodles fellow grower. I am not a grower. Or a pot smoking hippy douche. Ok I am.
