I have a 400w Mars in a 2x2 space and if I put it closer than 10 inches it burned the leaves in the center of my grow.. Look at my LR#2 journal . I would say 12 - 18 is the best as far as coverage and stress on the plants
:thumbs:GN for life homie :stylez rasta smoke::Sharing One:yeah don't matter about height mate just train your plants, and i would start under CFL as cocha suggested, Do you have a GN cocha?
Bam bro ,good to see your rockin in da house !... my suggestion is ...if either of those CFL's are blue / 65k ? use those to get started & swap to LED 2/3 weeks later ... I run both & have much better seedling health with CFL & only use 270w LED ... a 550w / 1200w LED for auto babies sounds overkill mate ?
Also if you get this grow right 1 plant will stuff that cab full ,although starting more does up your odds for success !
TD for a tough & forgiving strain is always a winner![]()
Fuck ... Any solution other than place the carbon filter outside of the box?you need the carbonized air to exit the tent
