T8 were all the range from the mid 1970's to the arrival of the T5, ensure you use the 4ft version as it's got the lumens to germ your 4-6 babes, at 4100k is the daylight color, a balance between warm red and cool white, make a rack of these 4 ft long with 4-8 tubes on the rack hang from chains in a closet put small fan in there, adjust chain daily, very little heat, but you do need tho have the plants within 2-3 inches, tho you can go all thru veg better to bud under an 400w hps, in about 2 months time, or bud under the T8's, remove all lower foilage, use warm white tubes for bud
Thanks for the info guys! Im thinking about using t8s for seedlings and clones until they are big enough to put under a metal halide to veg faster
