Well our temp is stays in the range of 80-85 degrees F and the humidity goes up and down but right now its at 50%. We havent got a way of checking the ph of our soil but you can get something at home depot or some place like that right?
If not, Fred Meyer carries them. Check around. You can get one that will work well enough for $10 or so.
As for the temp, they are too high!! If your temps only got up in the low 80's for a small part of lights on, it would be ok. But you really need to get them down. Try and shoot for 79 max.
