75% humidity, bad for drying?

1. so (hopefully) ill be harvesting my plant soon, and the space im drying it in is 75 degress and 75% humidity. Could this possibly fuck my shit up? I havnt had any issues with mold or anything, so id prefer not to get a de-humidifier to to take some of the water out of the air.

2. Also, where can i buy a timer for my 1000watt hps light?

3. And lastly, i was told i should get a reverse-osmosis system to water my plants. Coming from someone who doesnt really care about the very small details of growing, is this worth it?

thanks!

With good ventilation humidity is not so much of a problem.

75% is pretty high, I usually have it around 60%. Try to have some air movement in there..maybe not necessarily blowing right on the bud but you want fresh air in there and avoid stagnant moist air. Check for mold daily.

You can get a light timer at home depot or similar big box hardware store (or an indoor gardening place).

As far as filtering water it depends on the quality of water you are starting with, if the ppm of your water is above 100 or so or it smells sulfuric than you have hard water and probably want to filter it. Reverse Osmosis is good quality but a simple 2 part filter (chlorine and sediment) would be adequate and less wasteful/expensive

If youve already been growing with your water unfiltered and didnt have any problems than its probably fine though

so make sure you got some air moving around or they will mold.

i have been hanging some buds in my closet, unsure of humidity, and have a box fan blow air up and onto the buds at about 5 feet away and a window fan at the top to blow the air OUT of the closet. works good so far.

So I should throw a fan it there? Thanks for the replies guys. This is random, but I've got some plywood laying around, would it be ok to build my room from that and put some Mylar in there?
