RH too low??

Imnotmeanimjusttiredstarted grow question 5y ago

Hey guys, start of week 9 (flowering) here. RH in my tent is 30%, isn't it too low? Temperature always 23/22c. I have to water tomorrow but it usually doesn't go over 35%.

Solved

Week 8

Setup. Ventilation

Howdy. That may be a little low, even for early flower. In the final weeks of flowering, RH can be dropped quite low, but maintaining a decent RH in early/mid Bloom is helpful. If you're able too, try and raise it to 40-55% until the final 1-2 weeks of flower. A wet towel hanging from a hanger, placed anywhere in the tent, should give you the bit of moisture you're looking for. Free and easy👍. I'd wait for another answer as confirmation, this is just my two cents! Good luck and happy trails👌

Yes it's too low but you knew it. It's doesn't seems to be a problem so I guess there is nothing to fix

Hola! Yo creo que es una humedad un poco baja. Donde tienes puesto el termohigrometro? Piensa que hay más humedad en la planta que en la sonda, mientras no bajes de 30% yo no me preocuparía. Si no lo has echo ya, revisa varios puntos de tu espacio de cultivo y asegúrate que no baje de 30. Un saludo!

what I've learned from my own experiences is that if general room temps are somewhere between 20-26 , humidity between %30-40 doesnt stress most of my plants.higher temps with that level of humidity really stresses the shit out of them especially in late flowering. if yours dont show problem signs then you are safe.23C & %35 seems okay for this phase of flowering.I wouldn't worry a bit about it,they look beautiful.a good ventilation will do favor also

Hi dude! That humidity is quite low and you could try to add that towel for example to raise it a little bit. But if your girls look happy and theres nothig wrong then I wouldn't worry about it too much. Too much humidity combined with bad air circulation can lead to mildew and bud rot etc. I think that the high humidity is much more beneficial during vegetative growth. You can check VPD chart (Vapour pressure deficit) to understand optimum RH to Temperature ratios. Happy growing! 👌

Hi @Mothman your plant has beautiful colors.below 30 HR is that they usually give problems but it is really at the limit, the ideal is 45-55. place 1 or 2 tuperware containers half filled with water and controls if it is enough or rises too much, the evaporation of that water will raise the humidity of the grow. good luck mate👍
