There are UV LED's or COBs that give you the choice of Near and Far UVA, UVB, and UVC in 10 to 50 watt sizes. One solution if you don't like LEDs, is to buy or make a fixture for a tanning bed bulb (fluorescent), although I would use a separate timer as I don't know how long you want to use it on a plant. The LEDs/COBs run up to about $35, smaller individual LEDs aren't too expensive, but you need a bunch of them. The larger COBs might work out better.After some research, I am going to add uvb lights.
question. Where to get a good light at.
2nd, when do I add it to the grow?
This is my first grow but I am still going to give uvb a go and hopefully will get some good results
