Will need to see the specs for them bulbs to work out the correct distance & things paparose

Hope they are proper uv-b bulbs not just high output uv-a fanny teasers :smokin:

As to heat the 300w uv-b bulbs we use don't get that hot themselves, no wasting energy producing red spectrum & the heat that goes with that.

Love to see pics of them bulbs paparose :thumbsup:
alchemiser Reviewed by alchemiser on . UVA-B Questions I have 600, 1200 and 2000W UVA-B bulbs. (hps type not the flourescent) which is the most suitable bulb for a 18 Sqft area? (I have 2 X 400hps) At what stage of flowering should I use it? All the way or last few weeks? In flowering period, how long should it be on daily? Whats the suggested distance between those lamps and the plants? Rating: 5
