humidity level

Sorry to answer over others., but your fine where you are. Growing hydroponics there is plenty of humidity coming up and around your girls. Consider 26 to be around 45 around each girl. Humidity being low isn't much of an issue in hydroponics. Being to high can be an issue.

5th week of flower,i would stay on 50%-55%-60% 25 is kinda too dry G0od luck👊🏽🍀

With your temp at 26deg your vpd will about 2.2 ish. Way to high, 1.4 to 1.6 max is the aim. So either increase humidity or decrease temps if you can.

That’s a little too low for my liking. But your plants do look healthy Happy growing 🤘🏼😎

That’s pretty low yeah. 40-45% RH would be more preferable. But if this is all you can do then accept your environment for what it is. Your plant is still flowering. So you’re going to enjoy something at the end regardless. Cheers 🤙
