Humidity in the tent - is it a problem? Outside th...

Go with the buckets and a towel whicking water up by keeping one end in the water and the other suspended. A quick re-dunk as they dry and your set. Those little radiators are a nightmare with their dry heat dissipation. I use a tubular greenhouse one to good effect. Thankfully my lights create a perfect ambient temp now with the dehumidifier keeping it at around 60. I scored the thing in a facebook selling site for £5. they thought it was a heater. turns out it was a £200 dehumidifier. bonus. lol It makes life a hell of a lot easier for our damp climate in the uk. Air exchange is vital though and if heat is up you can use an exhale co2 to help your girls cope with it. they would thrive in that small space with a boost

100% get a humidifier. If you don't they will suffer. You want 40% rh in flower with good air flow. 😎

Hey my man, I had a similar situation aswell. The 20% RH are sort of a problem for germinating and vegging the plant (causes slightly slower growth as roots arent developed that well yet). Over the course of flowering, you want your RH to gradually decrease to about 35% to prevent mold in first place. Also keep in mind that in later stages of flowering, the plant will be way bigger and therefore will transpire way more humidity. Also, I learned from my past grows, that once the plant is adapted to the conditions and if it is only one condition thats a bit off (in your case RH) it doesnt really affect the grow that much. If you can, try to bump it up to about 35 - 40% during flower, but try not to go much higher than that (danger of mold and bud rot - so good airflow is needed aswell!). Hope that helped, if youve got more questions feel free to contact me ;) Cheerio my friend.

Humidity is really important. I bought a humidifier. Now it’s much more onder controle and much better for the plants. Good luck
