I'm investigating a CFL microgrow, and I would really love it if someone could help me with CFL penetration data. I just want to know how far CFL's penetrate, and while I forget the exact term, how far before the light weakens. The grow chamber will likely be 28 inches tall, and I plan to set it up so I can either move the lights or have adjustable stands to put plants on. Thank you!
I would, but cfls are cheap, and led I have to order. If one of the cfl stops working, I can have extra without much cost or time wasted. Not so much with led. For example, a cheap mars hydro 300 watt dimming led is 239.99. What if it fails? My grow is ruined, and I need another led light. More money. If a cfl fails, that's less than 10 bucks, and the grow continues as the other lights still work. They are less than 10 bucks a pop, 40 bucks basically for my needs versus 239.99 for a cheap led. It's pretty clear what is best for me. I am going to use cfl, it fits my costs and needs much better.
Cfls can and have been used to grow cannabis many times. A simple Google search brings up info. Probably more than you'd find here. Not many folks use cfls these days. They are great to veg a few plants but lack a lot when it comes to flowering plants. Vee suggests LEDs because they are more effective and can support the whole life cycle. If your worried about waisting time I'd seriously consider LED. If you shop around you can find deals. Good luck.
Damn If I don't learn something every day. Cutting them never crossed my mind. That is an interesting method (I refuse to call things a hack, too overused lol). I'll look into the real watt, the lumens, that sort of detail for cut led lights. Can anyone speculate about the penetration/spread of such lights? I'm only interested in microgrowing because of limited space, and trying to get most use out of the space I have. It would be all medical usage, not for fun. Trying to help a loved one with chronic pain with the very limited resources we both have.
All the more reason to get it right the first time. 30-35w per sqft is the norm most folks look for in a cannabis grow. Not real hard to achieve in a smaller space.
