Yup....the bottom line is that they're fine for vegging but yields suffer with LED. Some excellent LED threads here - check British Hempire's thread, and Mace's too.
Thanks for the quick response i've been up all night studying. I'll just keep it simple a florescent for seeding and clones. I'll use 2 600 conversions for my veg and 1 10000 for flowers what do u guys think
Divide the width of your space by the diameter of your buckets/pots and round down. Do the same thing with your length and multiply the numbers together.
