i'm using t8 shop lights (32watt) with a mix of warm and cool bulbs, and haven't had "leggy" veggies.. i do adjust the height of the lights above the gb - i have 3 pairs of lights over 1 pair of growbeds - a barrel cut in half
someone sold me an aquarium light fixture for 5 bucks, it was very bright but i broke the bulb when moving it.. after searching for a replacement bulb, i know why it was so cheap, i can't find one anywhere,, it's kind of a weird bulb, a little bigger than a t5 (a t5 barely slides right in), the pins are the size of a t8, and it's 45" long (about 45.75" pin end to pin end)
all i can read on the bulb itself is 54watt full spectrum..i've checked aquarium shops, hardware stores, and lighting stores..i ordered one online that the pic looked the same, but it was a regular t5 and it wouldn't work...
anyone looking for a cheap fixture? lol
