Will it make a dramatic differance vegging w/o mh or fluoros?

More stretch, lots of heat, more electricity than you need to use when your plants are still small. Invest $20 in a pair of shop lights and some T12 cool white, daylight, or kitchen and bath bulbs for them. Problem solved. Read the continuous canopy sticky for more detail on why this is better.

Edit: Nice ass. :D

Yeah, until I switched to T5's I did all my vegging with shop lights and they'll do just fine. Cuttings will root and reach 12" under shop lights in 5 weeks.

thanks, this is a question i thought i knew but: if u have a regular hps bulb can u get a mh switchable bulb without a combo bllast?

What you are looking for is called a 'conversion bulb'. I think there's a bunch of discussion about those in the indoor lighting section but I've never worked with one.

dj00140 ,yes you can get a conversion bulb.

I went to purchase a MH>Hps conversion bulb and for me it was not cost effective.
The spectrum was a little different than I wanted and the cost was over 1/2 the price of a complete 1000W HPS system.

I shelled out for the whole system, about $200. A friend spent that on a hi-end conversion bulb.

you can get a conversion bulb or you can get an HPS ballats with a compatible ignitor with the HPS, and get an 35uF capacitor, then you dont need the conversion bulb you can use mh or hps.
