MindSoup Posted December 31, 2021 Share Posted December 31, 2021 (edited) At the bottom of a valley albeit a very shallow one, I also crowd my tent to fuck which probably doesn't help, If found Bluamts/drippers exacerbate the issue as well.

Guest Posted December 31, 2021 Share Posted December 31, 2021 You need to draw cool air into your lung room or tent from outside. When you bring cool air in and warm it, the rh drops off considerably. It shouldn't matter that the rh is sky high outside. It's the temperature difference you want. If its cold outside my rh is usually in the 40's. It's a bit too warm currently, that with the rain is making it unusually tricky this time of year.

MindSoup Posted December 31, 2021 Share Posted December 31, 2021 (edited) @fatboy77 surely you'd be better pulling air from inside the house? Already warmer and drier. Edited December 31, 2021 by MindSoup Link to comment Share on other sites More sharing options...

I have friends who are able to maintain 50rh lights off. As said I have topped and topped and they are taking a lot of water. Average of 3l per plant a day and they are light in weight the next day. I've tried less water no run off to stop excess water and straight water to keep ec right but didn't change a thing. Removing run off. I aim for 20% run off to keep my ec in roots correct. Tried Covering pots. It's as soon as the lights go off. No issues at all with lights on. 1 Link to comment Share on other sites More sharing options...
Guest Posted December 31, 2021 Share Posted December 31, 2021 Windows. You need an airflow. I'm south coast too. Most my plants need watering twice a day, so 5L each. Rh is 55 in my tent and I can drop it lower if I want. If using led try running lights on during the day, it's colder at night so the cooler air drops rh. You can swap 12/12 from night to day pretty easily mid cycle. Link to comment Share on other sites More sharing options...

But the room drawing air from is not heated either. Although inside. So the room that feeds the grow room sits at about 18degrees Link to comment Share on other sites More sharing options...
