Keeping humidity up

[coolballsdave]

If you use a tub that seals well there is no need for seal a meal,
Seal a meal isn't necessary with the substrateless method and is a good way to get too much humidity imo.

can a tub get too humid? From what I understand as long as there is no condensation on the walls or lid of the tubs the humidity doesn't matter. Am I wrong about this?
