Hello my friends. So I’ve gotten my first grow kicked off and my seedlings have emerged! Yay! I read somewhere (maybe this forum, maybe reddit) that the high humidity of the seedling phase can have a negative effect on your carbon filter and possibly your LED lights as well.
I got worried about it and turned my fan off. The problem is now my humidity is stuck in the mid-high 80s. Before that I had my environment dialed in, which took some time and I was pretty impressed by, considering I’m using a cheapy humidifier (it does have a humidistat) and a tiny non-digital space heater.
Maybe I’m wrong here but I use the dome technique which I believe keeps the humidity within the dome and doesn’t effect the tent RH in general. Also think its easier to control dome RH than entire tent. My 2 cents.
I specifically use hose clamps with big convenient wing nuts on my exhaust line to my filters because I keep them disconnected until my plants are far enough along to start smelling. Good quality filters are expensive, there’s no point in wasting their life expectancy on seedlings. Just run your fan without the filter, and then simply connect the duct to it when the plants start smelling.
