Lighting Question

While in the 1 month of growth has past could I replace white light with UV-A light for stimulated plant growth, then switch over to UV-B light for flowering? Just a thought, And UV-A is the same light as a black light.....

Ok i'll answer my own question..... UVA (blacklight) makes the plant grow and expand at a faster rate. So get about 300w of black lights and you'll have a bigger plant, As for UV-b it "burns" the plant *UV-b means (ultraviolet-burning)*

nope, because when using HPS bulbs it's got a blue tint=more energy and i'm to lazy to go into energy transfer...

Ok, am I crazy here? My MH bulbs put off a bluish light but my HPS put off an orange-red color but your HPS bulb puts off a bluish light? Do you know the brand name and what wattage it is in by chance? I would like to check it out. Maybe I have been doing something wrong?

I fail to understand how we went from talking about uva/uvb lighting, to hps.

300 watts of UVA (blacklight) is 300 wasted watts. Blacklight does precisely fuck all for weed plants.

Some UVB (which doesn't stand for "burning" btw) is thought to be beneficial, in regards to increased trich production, but should only be used as supplemental lighting. UVB is a form of stress, and should be used with care. It has also been shown to be a growth inhibitor, so you shouldn't go overboard on UVB wattage.
