My temps are getting into the lower 80s during the day with only a max of 37% humidity. At night, my temps get as low as 68 with humidity at 54%. Can someone plz tell me how i can keep humidity in my grow closet?? I only have a 400w MH and it gets hot, so i have the light at about 4 1/2 foot away from my seedlings and clones..... Also, could someone tell me where to buy an hps setup? My hps won't work in my MH set up but i'm looking to buy an hps lamp since i already have the hps bulb for my flowering. Do u have to make/set up your own or can i just buy one?
. 80 is to high I would run you light during the night like 700pm to 100pm at 75 - 80 degrees lights on 68 sound good for lights off. you want your grow room to be 10 to 12 degrees of difference lights on/off if temperature keeps going down just add a heater behind of a oscillation fan. don't worry about your humidity they still too little. basically controlling RH can maximize yield and plant transpire less water.
