I would say either a 250 MH or a T5. I have a T5 with 8 bulbs in it that are 2 feet. And every plant loves that dam thin like crazy. IM sure a 250 would be good, but for veggies, The T5. I have 2 cilantro plants, and have had them for about 5 months now. It grows fast enough to eat off of and keep re vegging. For hebs its perfect. I have put them in my flower rooom, but it was a mistake, they flowered and less cilantro. So continue to just leave them in veg cycle, feed tap water and grow big and bloom big and they will spring to life like crazy.
