Help with led growtent setup

[HerbalEdu]

Will i still have no prob getting negative pressure even if i make a 125 mm hole for passive air?

my passive intake is a single hole with a grid 15cmx29cm

passive intake + extractor create negative pressure inside the tent.

HerbslEdu and others here have said passive air is enogh. I got a 220 / 280 vent extractor inline fan with coal filter il use. I hope i can run it on lowest setting 220 for lower sound with negative pressure.. Climate in my country isnt that high, so if it works for herbaledu in france it should work in norway?

How do i know of its enogh fresh air i the tent? Or is it just humidity and temp that mathers

There is a formula I can't remember but something like every 15 minutes it all needs to be refreshed Fans are rated in Cubic feet per hour ( I think, old bad memory )? and I think mine is a 135cu/ft/ and its a 4" I use with a dimmer switch I hot glued to the side.....Its on full slow now..I turn it up when I want to cool it down

you can always start attempting controlling temperature and rh but it quickly become a hassle

cannabis can thrive even with far from optimal growing condition so i wouldn't bother controlling thoose parameter with your first grow, i don't even control mine after years growing. weather is just what's the weather's like and that's all always better than no weed at all in illegal country

extractor fan shoud pull in in a good extra amount of air via the passive intake aswell?

about the drying. i got 2 types of seeds to grow: g13 haze and northern lights autos. planning on trying outdoor grow aswell too see if its worth it in this climate. so i could move all my autos out there to avoid buying extra tent to dry in. just a shame if i dont get to taste the northern lights if outdoor setup fails .p

Btw do you harvest all plants at same day if its same strain? Or could it go days between each plant harvest?

If you have a separate space to begin drying harvested plants while the others finish, you can stretch out the harvest. I usually shoot for a 1 day chop. Simpler.

So you chop tjem all same day? I think i have to do that too, or else il prob ruin motherplant since its 12/12 there and veg tent is dark for drying.
How would it be to just let motherplant stay in some dark for some days? Vs keeping her in a 12/12 light room intill all plants are rdy to dry?

as a new grower it's like pringles, once you chop you're probably not gonna stop until they're all gone lol

Dont you look at the tricones what colour they are before harvest?

i go by the trichs on the buds, not the sugar leafs

Here is my growsetup for now:
You can see fan and filter still on the ground,. Waiting for some parts. The pots with soil you see is just tomato seeds and sugar snap peas. I put out the temp, humid measurer and saw my temp is way to low, so i moved an oven in to heat up.
Btw, the little measurement cable coming out of the temp/humid box. Where should it be put in the tent for best measurement, and is it humidity or temp or both it measures??

64 rh might be a bit high near the end of flowering, but well my own rh vary from 20 to 70 depending the season and the weather

rh inside the tent is usually slightly higher than room rh especially at night

Should i put the RH measurer abit above ground in tent? Thinking it could be abit more moist there incase of water spills n stuff

you usually want to monitor temperature and rh just above canopy level

i keep my light on 16/8 as soon as i plant the seeds

FWIW, I've always tried to replace all the air in the room every five minutes. Pretty easy to
calculate the total cubic footage of the grow space (length x width x height), and once
you have that number you can select an appropriate exhaust fan.

My flower room is roughly 450 sq. ft, and I use a Vortex fan that moves roughly 500 cubic
ft. per minute. I have it on a speed controller and run it at about 25% power. A quality fan
is important as you don't want your plants sitting in stagnate air, plus cheap fans are noisy
and it'll drive ya nuts.
