Okay first off keep the lights off for 24 hours if you want to switch them. I have done it dozens of times and never had a hermie induced by that even in week 8 of flowering. Second don't bother with that bullshit CO2 rig. Consistency in CO2 is a lot better than the spikes and drops of that...
Not true they don't need a specific bulb for flowering those 4100k 65w cfls should work like a charm. However the 2700k spectrum is more ideal for flowering. But a balanced spectrum throughout the grow is best. So mix up the bulb's color temperatures. Also Homedepot sells a 68w cfl for 14$ that...
I really hope this thread is a joke. If you put red saran wrap over the light the only thing it will do is filter out all the light which isn't red. If you can't afford new bulbs or a new light just flower with what you have. It will work a shitload better than covering it in saran wrap.
Just slow down for a second. 65watt cfl does not equal 300 watts. It is 65 watts but puts out the same light as a 300 watt incandescent. 3 of those will not fit in a pc box trust me. One or two maybbe. Go to home depot they sell em for 15$ a piece. And you will need to have a shit ton of air...
There should be a number on it that ends in k like 2700k 6500k or 4000k, make sure it is between 2000 and 3000 or 5000-7000. That will be your best light sprectrum.
Autoflowers being unnatural? Maybe you all just don't know what natural means. Because there is no difference in an autoflower than any hybrid that you have tried. Autoflowers are cannabis ruderalis plants that have been selectively bred with indica or sativa strains for only the autoflowering...
It can't pollinate your flowers on a 20/4 cycle, It will not start growing balls until you start to flower. It will show its sex in veg if you wait long enough but they will just be preflowers and will not grow pollen.
