I got 1 Diesel plant (Had another but its dying) im adding 3 more (got em germinating right now) So I got 4 Auto Diesel and I want to buy a light kit for when seedling stage is over. Im thinking of buying a 150w or a 250w light kit with MH and HPS. But space is limited. How close can I get the 250w from the plant and how far should the 150w be. I only have 1f 2" from the top of the pot.
