To be honest, i might take back that swamp cooler. it was working great the 1st few night but now it seems to have lost its will. the RH% isnt to high 20%. these things arnt cheap. i will wait until its in the 95's and give it 1 more go. its only been lowering the room 2-3F* lately, and 2-3F isnt worth the $150 i paid for it. tomorrow it should be pretty hot, so i will see.
Yeah mine isnt as cool as it was.But its been about 95 outside with high humidity.temps in my grow area have been topping out at 80-85.Half to keep the unit full of ice and I open the door to let some air in from the larger window swamp but raises rh quite a bit.Going to keep mine as its still better than a fan but its alot of work keeping ice in it and its only going to get hoter.But all in all i guess if i oscilate and keep air flow hitting plants it seems to work for them.Not much for me but it is still 10 degree difference and rather have cool rh than warm rh.
