I've been vegging my plants under a 700w LED light and the results are fantastic. I've gotten way more tops, almost 1inch of growth every couple of days and the plants are healthy. Also the lighting bill went down about 10$. Highly recomended for expert growers
What wattage metal halide was it? I have just changed from a 250w MH (uses 260 watts) to a 450w LED (uses 275 watts) so the new LED is a bit more expensive to run, but they are very close. The heat that is given off is pretty much exactly the same on both lights. I'm hoping for tighter internodes but it hasn't been on for even 24 hours yet so time will tell lol
they have super tight intern odes in veg IgOTbAdAdDs0rRyIfICoNfùSeDu #d@bbin I can't speak for flower yet IgOTbAdAdDs0rRyIfICoNfùSeDu #d@bbin
