I veg mine under cheap 23w cfl and reflectors from hardware store. I found plants did better for me under the cfl than my mars led during the first maybe 3 weeks. I add more than 1 as it grows a bit. Hope this helps, i think i spent 20usd on 2 clamp reflector lights and bulbs. Also t5 is t5, only difference between a t5 shop light and t5 grow light should be the bulbs.
