Humidity question during flower

Hello growmies, happy mothers day as well. I have a simple question about my temps and humidity. On days that I water humidity goes up to 45-48 and the temps are around 75-77 daily. When the soil starts to dry out it drops to about 30-40 humidity. I was wondering is it okay to fluctuate that much during the flowering stage that I’m at. Today is the last day of week 7, Tomorrow will be the start of week 8

The fluctuations will be okay. But that humidity seems low that early into flower.

That’s a VPD of 1.9-2.0. But they look great soo.

I was reading online that this was the humidity for this part of flowering, I wasn’t totally sure. Like at the moment my humidity is at 50 right now. Should I raise it or keep it at 50?

Variation is okay, but you don’t want to be above ~50% if flower. I’ve ran low humidity during the Winter. It hasn’t been a problem before (at similar levels.)

Time in flower is all that matters if you are thinking about harvest dates. Those flowers look to be at the 2nd or 3rd week, so you have 5 to 7 weeks to go before harvest.

You want your average between 50 and 60 in the early stages of flower.

I’m at week 8 from seedling and they are autos, I have been at about 45-50 tbh most days cause I water like every other day since my plants has been drinking a lot. I do see that my humidity does go up at night to about 60 the most is that a problem?

Don’t struggle to get it perfect because then you can cause more fluctuations and issues, I’m simply saying it is on the lower side but they look healthy.

I’m only trying to explain that ideally you want around 50-60% this early. But it doesn’t need to be ideal, it just needs to be within an acceptable range, there are no laws when it comes to growing just best practices. This is just to inform you.

Gonna have some awesome flower my friend!

Humidity with lights off can be a struggle,
Right now no 60% humidity won’t be a problem at night and probably healthy. But come week 5-9 of flower you will want to maintain low 50s at the highest.

Your humidity is ok if you keep it under 60 but drier humidity in the grow room can be inviting for some pests
