What is the limits ( humidity and temperatures) fo...

Hey there Jaggie! Optimal temps Veg: 70-85f Flowering: 65-80f | Optimal humidity for Veg: 40-60% Flowering: 40-50%. I will not go into those base temps/RH levels as others have already. A good thing to mention is that the optimal temps change based on your humidity level and vise versa, because temperature of the air effects its ability to retain water. Your plants breathe through openings in the bottom of their leaves called stomata. Stomata inhale C02 and exhale oxygen+moisture. The pressure difference between the inside of your plants and their outside atmospheric environment impacts the rate at which your plants transpire moisture into the air. A high VPD (Vapor pressure deficit) means the air in the tent can hold much more water (RH is low!) and this causes the plants to transpire more water into the air through its stomata. A low VPD means the air has nearly reached moisture saturation and the plant will not transpire much. Both a High and Low VPD can cause problems! Here is a graph with Temp/Humidity relationship levels. Get as close as you can to the target temp & Humidity then refer to this chart for optimization based on your situation. BEST OF LUCK! 😎 http://bigbudsmag.com/wp-content/uploads/2017/04/bbm-04-17-2017-resized-1024x768.jpg

hey dude! The previous answers are spot on about ideal conditions, however do remember to not ruin the fun of growing trying to make ideal conditions. I run my entire grows at 40-50% humidity and have yet to run into issues. As far as temps go since I see you are running LED research has shown that temps kept closer to 80F/25C allow the plant to better use the light.

Hi @Jaggie1983! Seedling stage : 65-70 % RH & 20-25 C°. Vegetative stage: 40-70 % RH & 22-28 C°. Flowering stage: 40-50 % RH & 20-26 C°. Hope this will help, keep us up-to-date and happy growing 👊
