I'm pretty new to all this, but I have been doing a lot of reading lately. First, how many 23w cfl's did you veg that thing under? I'm really interested in the potential of cfl's on small scale gardens. Second, I don't believe you will be satisfied with the results of a window grow. As others have said, the amount of light received in a window sill will not be enough to supply the plant. If it does initiate a flower cycle, it will most likely stretch and produce poor, loose buds... that's if it doesn't Herm. Also, in my opinion, the transfer from window sill to dark box (for 12 hours of total dark) will be an unnecessary stress on the plant. Since you are already using cfl's... I would suggest constructing a small flowering box and use additional cfl's. All you need to make one is a day off and a home improvement store nearby. Read through some Sticky's about how much light plants need, the spectrums they desire, etc.

If you do go for a 100% indoor flowering process... make sure you look for the CFL's rated 2700k (usually Soft White) as they are more appropriate for flowering. It wouldn't hurt to throw in 1-2 of the Daylight 6500k CFL's too... plants like both spectrums just at different levels and at different growth stages. I've read a 3:1 ratio is good. I understand it can be frustrating when asking questions on here. Especially when you just want to know if what you are doing is going to work. Just know that there are thousands of people doing thousands of different things... with thousands of individual experiences. So they may not fully understand what you are looking to achieve. I've found that if you aren't completely obsessed with growing and just want to try your luck and grow ANYTHING smokable.... just post a thread saying, "Hey, I have no money or supplies... can I flower a plant in a window sill?"

And people will tell you....... their opinion..... lol
Remember 1,000 people can tell you it won't work, but that doesn't mean you can't give it a try and shut all of our stupid asses up. Haha. Hope this helped. Have fun and keep it green! :rasta:

Damn... I write a lot. :jointsmile:
