MaryJaneUSAstarted grow question 5 years ago
If I buy a cool mist humidifier for my grow room, will it decrease my indoor temp and increase my RH? Also, with a duct fan sucking up the air out of my grow room, how effective will it be? Unless I slow the air flow down. Thanks!

It will indeed lower your temperature and increase your RH. Your humidifier will work a little harder to maintain your RH that you set but that's it. Your exhaust is necessary to maintain a proper temperature in your tent. Use a VDP chart to find the perfect temperature to RH for every stage of growing. If you want PM your email and I'll send you an excel sheet that you input your data and you'll get the exact range required for each stage of a plant life cycle. Cheers.

hey there, i use a mister in my new growing set up , so let me tell you that it works great, in fact i won't ever grow without it. I have two 150W 1330M3/h exhaust fans (that s pretty big) and the inside the tent RH is hardly affected. I would not compromise airflow at all, especially not the exhaust - never turn your exhaust off ! So all i can say is that the mister will increase your RH some, but shouldnt really lower your temperature by more than a few °C. Hope this helps ! 🚀

Northern Lights Auto, quite short and bushy, fan leaves shielding light - should I defoliate?First time grower with a quite short Northern Lights Auto in week 6. The fan leaves seem to shield a lot of light from the inner leaves, also touching ground. Should I trim the fan leaves? Or should I keep them, since it already seems stressed enough for it's short life…

Remove leaves from auto?Should I remove fan leaves from my auto flower? I wonder since it is so crowded, I worry a bit that the leaves are pressing against the buds. But maybe that isn't a problem? I've read that removing leaves is unnecessary and stressful for the plant.

Defoliation late in flower on Auto'sI like to defoilate, If I were to pick majority of the fan leaves off of these plants being Auto's, will they react or stress too much? I like to defoil near the end of flower to really push all the focus to the budsites. Happy Growing!10 months ago

Defoliation AutoflowerHey fellow growers,
How should I approach defoliation with autoflowers during flowering? I'm thinking of removing lower leaves, especially near the soil. I prefer to be cautious to avoid mistakes. Reddit wasn't helpful as it seemed too critical. I hope for better insights here.

Removing of Big Leafs in Flower Phase ????Does it make sense to remove large leaves in the flowering phase to give the plant the opportunity to send more energy into the flowers or should you leave the larger leaves on because the plant also photosynthesises through them.

First Grow Help And FeedbackHello Grower,
OG Kush Flower Day 24: Lollipopped and defoliated 10 days ago. Can/should I defoliate again? The buds seem like they could get more light. Also, I noticed some sprinkles on the top leaves—could this be from too much P/K? Any tips and general feedback are welcome!
