I read a whole book on growing before doing this and just bought the mh because i had the money for it at the time. I measured the lights distance it was about 2 and a half foot away from the plants and it still was burning them. So i have a polytunnel at home so i decided to put them in there for a few weeks to heal them and get a bit of size then will move them back in to the grow light. So what ideally should the distance be between the mh and the plants if either of you guys can help? Thanks for the advice guys
Alfiecarted Reviewed by Alfiecarted on . Problem with seedlings? Can anyone help me to identify problem? I grew last year outside and had a very successful harvest so i decided to have a go at inside growing. The problems i am finding is the browning almost burning of leaves on the seedlings. I have the light at about 18 inches away maybe even more and it still seems to be burning the seedlings. I have a fan constantly on the circulate air and keep the temperature down. I am using a 400 watt metal halide light fixture. Can anyone suggest some ideas and will they be alright in the long run even Rating: 5
