dude, i'd keep to envirolite's for all vegging. i dumped all other lamps in favour of these. From cuttings under a 125w, up to the plants under 2 200w lamps. You cut quite a bit of time of your grow cycle and get far more stems with these lights. found them a bit naff for the flowering stage though as the plants still need a small amount of veg light in flower so you end up using 600 - 800 watts worth of light which proves uneconomical compaired to a 600watt hps. had exceptionally good results by using both, plus your hps bulb lasts longer. nice plants by the way.
