My questions to the community are:
- Will any red LED do?
- Does the exact wave length matter, is 630nm okay?
- Do red LED's emit UV?
- Does the wattage matter?
- Cheaper units start at 14w.
- Some of the intermediate units use 90w.
- And of course, what are your thoughts on cheap and safe sources of red light?
I'm in the middle of a flare up and I'm willing to try something new. I tried red light at home before without success. I attribute this to the fact that I only tried it a few times and I used a fluorescent light which tended to get warm and probably emitted some UV.
From what I can tell, growers are also averse to UV ... which could be to our benefit.
Any help, feedback or wisdom much appreciated.
