If your running a sealed room, a dehumidifier is absolutely essential. I hope that your not too far along, b/c where i live 70-80% humidity equals bud rot. I have a couple dehu's and they both have on board humidistats, which i have found to be pretty unreliable. Buy a separate humidistat to control the dehu, simply program the humidistat and plug your dehu into it. Also install the drain hose on the dehu and lead it to a drain, that way you never have to empty the bucket or worry about the bucket being filled and your dehu turning off, subsequently turning your room into a fungus growth chamber. With a humidistat and dehu with the drain hose installed its completely automated and you have to do nothing except to check that everything is functioning properly, and a hygrometer will do that for you too. Now the dehu gives off heat, so you may need to invest in an a/c unit sooner than you think. IMO an a/c unit is absolutely necessary for a sealed room as well. Hope that helps.
