Sounds good....Both Markass and I have been having humidity issues these days. When I asked around I was told to try to keep my humidity level down to the 30's to avoid mold issues but my plants are in flowering and that may not be the same as for veg growth. I would doubt that you would want it above 45 rh however......dusto? Thoughts?

good job on the tds pen. Once you have all the bugs worked out you'll be getting some good wild growing going. :thumbsup:
