    Ventilation clarification.

    My grow room space is 3 1/3" x 4" x 6" the fan is a 6in 235 CFM I think. and the other fan is the same, should the carbon filter fan that blows outside be a lower CFM? I'm not too sure about the temp but I'm use a 600HPS with a reflector.

    Snapped Seedling?

    I have a seedling that is about half an inch long. Its still partially in the shell, and today I looked deep inside the rockwool hole and saw that the root at the bottom was partially snapped, near severed!! Does this mean my seedling is going to die?!
