People have failures all the time using the paper towel thing. Not talking about germ failures...I'm talking about sprouts that don't make it once they get into media. So...do so knowing that you may kill 1 or 2.

Cannabis plants are 99% water. Rh is the water content in the air, at the seedling and vegetation stage high humidity won't affect the plant. However, once you're in the flowering stage it's best to keep humidity below 40%. 83f is on the high end but should be fine in that stage aswell

15L / 3.9 gal airpot, growing autoflowers and figured I'd start it in the finishing pot to avoid any unnecessary stress.
Medium is happyfrog and 'living soil/supersoil' in bottom 1/3 of pot, remaining is 1/3 straight happyfrog then 1/3 warrior lite starter mix on top and down the center in a funnel shape

how long did it take to pop thru the soil

Partially correct, partially incorrect...humidity affects every part of photosynthesis...which is the biggest denominator in the veg cycle (weeks 1-4, 1-5, 1-8, depends on how long you veg for)
Google you a good vpd chart for cannabis and follow that for your humidity as a general guideline, just know that it is definitely okay to veer a little outside that range from time to time (in other words, dont be like me and stay chained to the hygrometer), but if you want to optimize your growth during veg cycle, there are definite and precise parameters you should follow........................keep humidity as low as your plants will allow during flowering, if you're cooped up in a tent it will be hard to get to the recommended 45%, otherwise you risk bud rot................

The next morning, but I pre-germinated. soaked in distilled water for 14 hours then used paper towel method.

It took a total of 4 days to break soil from when i started germination.

thanks for the info, I enjoy learning to dial stuff in!

60 hours and they have started emerging from the depths!
Mephisto Northern Cheese Haze
soil tempature below
under the humidity dome temps below
Actual room temp below
No soaking with water in glass or in papertowels just straight in the dirt and keep wet...
Now I got to figure out light intensity for early seedling...
For germination I adjusted the Fluence 2p led down to 15% at approximately 20inches above the top of pots...

I always worry so much until my plants are established. Higher humidity I think is ok because they are needing what they can to hold on to what little water they have. Ss far as light the light strength I think is less important than if they stretch or just moving the light closer if they do start to.over stretch.
Im in the exact same boat .. any results dialing in that dimmer and height for veg ?? Any thoughts would be appreciated looking to pop seeds I have ASAP running fluence 2p on a trolmaster in 5x5 gorilla

at this point I suggest -fluence spydr 2-p (autoflowers)
18inches @ 20% until 3days
18inches @ 30% until 7days
18inches @ 35% until 14days
18inches @ 40% until 21days
12inches @ 40% until 28 days
8inches @ 50% and that's where i'm at currently
going to increase intensity and distance of led to 15inches @ 100% as they progress to late flower (autoflowers)
You may can be more aggressive with the light - but i know you will be safe starting with above recomendations
Thanks my man , going to use this as a baseline see how it goes .. how you doing with stretch so far ? Was worried about the spectrum
