Kind and wattage of seedling & veg lights
I don't think you're going to find T5 fixtures at the Home Depot, bulbs yes, fixtures doubtful. They're new and still pretty expensive, and generally only available in specialty shops. A couple of inexpensive T8 or T12 fixtures should get you going. In the four foot length T8 bulbs are 32w i think and T12 are generally 40w. They have the lumen rating right on the factory packaging, your best bet is to pick out the bulbs with the highest lumen rating (from what I recall seeing the variation in t12 bulbs was a range of around 200 lumens).
warfrat73 Reviewed by warfrat73 on . Kind and wattage of seedling & veg lights Are two wide spectrum 2 foot plant growth / aquarium T-12 tubes (20 watts / 750 lumens each) sufficient for a for a 2'x2'x6' grow room? I'm only planting 10 seeds in rockwool plugs in dome propogation tray. I'll keep them under these lites for the whole veg. cycle also. Is this enough wattage? Would four T-12 tubes be really much better and worth athe added cost? Home Depot said the 20 watts gives off more than a regular 20 watts (hard to understand this concept). Its the highest Rating: 5
