Help needed please

I'm growing in a basement which had a window and back door which I leave both open day time my buds are nearly done but I'm sure there on the verge of getting mold cause of the night time humidity when lights are off the temp goes down to bout 60 humidity shoots up to 74 what can I do before they all get destroyed ?

Purchase a dehumidifier ASAP.

Good luck and keep us posted.

put a fan on them keep the humidity down

I have a fan blowing in the tent , running 24 h with the extraction fan . I think I've over flushed them an the wet soil has not been able to dry even though the temps get high with my 600 hps light on . I try keep the room cool as poss but night time humidity I don't know what I can do to help it . I'm planning on cutting them down Tomoz night . So with a dehumidifier were would I put it ? In the room that the tent is in ? Or in the tent were il b hanging them up to dry

if your planing on cutting them down soon the i would just get a small dehumidifier and put it in the tent if you have room

Well I'm on my way to pick up a portable a/c unit I don't think its going to fit in the tent but maybe it will once the plants are off the ground and hanging up . With it in the tent though won't that make them dry up too quick with dehumidifier inside?
