wot lights
if your using bulbs, ie beanets, it wont make a difrance to the make there all prity much the same but if you use long bulbs like a underlighter for say your kitchen, your best to use a daylight bulb, you can get these from your local holesaler, if they dont do it you'll have to get them from a pet store but will cost alot from a pet store, you might be able to get of ebay? but the cheepest would be a 2 foot underlighter from a eletical holesaler, where im from i can get these for £6.00. the same thing from a pet store whould cost betwen £15 to £25 depending on the store, a daylight bulb has the bigest spectrum you can get with out spending big doe and is as good as a philps full spectrum bulb, a bule bulb is a must when your veging, the blue spectrum is most used buy the plant at that stage og its life, you can buy these for around the same doe as the daylight bulb and should give more gearth and biger yeld, hope this helps and good luck with all your grows :harvest:
