Using plastic wrap for dry method

[rthomas]

Thank you Tom for pointing to me the alternative of using plastic wrap to maintain the moisture of tank when using the dry method to grow HC, glosso etc etc.

As that thread is already closed, I just wanted to know how much opening should I leave (unwrapped) to enable the exchange of gases. I don't think we should air-tight the tank. Please advise.

Any take on this?

You don't need much, half an inch gap is enough.

unless you're really good with plasticwrap, there will be plenty of air circulation in the tank.
