Hey everyone im new to this forum and a bit new to growing "medical" marijuana. i just had a question about black lights, will they work just for the seedling stage? just until i go out and buy and actual light? Thanks.
If 23w you'll need 4-6. Lowes and Home Depot usually have 42w and sometimes 65w. Make sure you are getting 6500k for veg although about 1/3 2700k is good. You'll need much more light as they grow and in flower a shift to mostly 2700k.
