High there
Between 40% and 75%.
Only cuttings need real high humidity (85%/100%) so they can root, water is absorbed by the leaves. Always in a dome because you dont want to have these high humidty levels in your tent..
I agree. When it comes to starts I don't treat them any different than plants in veg. Not much humidity here so I never have to worry about to much. That makes things much easier. The more plants in the tent the better for me. I have had starts and plants growing fine in 30% humidity. What works and what is perfect are 2 different things.
For seedlings, I tape a plastic sandwich bag over the top of a Solo cup. After 48 hours, I cut a corner. After another 24 hours, I cut the other corner. After 5 days, the bag comes off the cup. I have even used clear plastic cups on top of Solo cups to make domes.
1L and 2L clear pop bottles cut in half work great, plus with the cap you can loosen and tighten it to control how much humidity you want to form inside the little domes.
