    Default Answered: 600w mh light distance early veg

    hello im just wondering if anyone can help me work out a healthy distance for my mh bulb i know people use 400mh in veg but this is all i have to work with right now. ive read stuff on the net and people seem be hanging them really high up at like 80cm - 100cm. i just dont want them stretching up for the light or stretching out of it.

    thanks for your help!
