Worried about my humidifier I just bought causing mold need advice.
Cannabotixstarted grow question 7 months ago
I live in a dry climate where I have a need to adjust humidity.I just bought a Ac Infinity humidifier to add to my tent. My worry is if I add a humidifier won't a humidity of 60 and above cause mold? How do I prevent this. I have exhaust fans and a ocular fan moving air but worry

With the exhaust fan and a fan in tent to move air you should be fine in veg and stretch period around 60-65%. When you start getting buds aim more for 50-55% if you can. Last two weeks of flower 45% even better.
I usually run these numbers and have not yet had mold issues. It's really all about good VPD, if you download a chart (lots of free ones) it will show you what RH to aim for based on your grow space temps and plant life stage

70 and above and don't run it all the time or run it in the room that air comes in tent from. As long as your humidity is above 40 you should be okay

4x4 16 Plant Veg Time and TrainingHello guys, I am planning on flowering these 16 ladies in my 4x4, but I am unsure of how long to veg and what training to utilize for maximum yield.
I was thinking 3-4 weeks? Or maybe longer?
Is topping in such a tight space a good idea? If yes then at what time?
Thanks!2 years ago

DWC×2 33cm H fit in 70x70x160it's not Q about my grows, rather my new to be set up. So, I ordered 2 19l DWC by growrillahydroponics. They are 33cm H and the tops are 30cm in W. With a 70x70x160 do you think I'll be able to hold 2 plants thru veg-harvest or will I have to swap them out giving em 12hr each?Setup. Other

Should I remove some plants yield wise ?Hello ! First grow. I wanted to know if it would be better to remove some plants if we think purely in yield. I'm just having fun, these are 5 different automatic seeds, I'm not only interested in harvesting the most.This is just out of curiosity.
This is a 2*2ft tent (60*60cm).

Air-Intake / Equipment question.Ok, so i bought a air outtake system for my grow tent with a active carbon filter so my whole house doesn't smell like weed as it does now. My question is can i just install my air outtake in there and close the tent without having a air intake ? Or will that cause Problems ?
