I use t5's for vegging,but went to home depot and bought 3 4ft dual bulb t8 fixtures and bolted them together to make one bank,but i prefer to use the daylight bulbs 6500k for vegging,this setup was very cheap to buy and assemble and has proven very useful for seedlings,vegging or growing big mamas. I also use t5's for vegging,they produce more heat i find,but its all personal preference and what works for you!
these were grown under the t8 bank
