How much desibel does your fans make?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.
I've a bathroom fan I boxed up with input and exhaust ducts, its been running 24/7 for 3 years + pulling air out of my veg closet......pretty cheap and silent & works greatFWIW, I've always tried to replace all the air in the room every five minutes. Pretty easy to

…and this year’s MacGyver Award goes to…. PC!!I've a bathroom fan I boxed up with input and exhaust ducts, its been running 24/7 for 3 years + pulling air out of my veg closet......pretty cheap and silent & works great
I new a guy who blew in foam pellet insulation by dropping a bathroom fan with 20ft 4" exhaust duct into an extra large bag full of pellets.and directed it where he wanted the insulation to blow into. With a 10ft pole attached to the end of the duct he filled his attic with free dangerous & against the law pellets to use because of fire code. but free insulation in a 200 year old home...it worked amazingly well and gave me my idea to use them to direct the air where I want it to go.…and this year’s MacGyver Award goes to…. PC!!
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??
So nothing growing yet, right? Because at 18c it’s too cold for seedlings. And yes, an LED lamp will most likely give you some heat in the tent.Next day, temp improved
I hope the lamp wil make the temp later, or else its gonna be expensive keeping an oven outside to heat up theshed
i see 26 celsius seem to be optimal temp for germination. and when growing 68f to about 77f , should i try stay in middle between 68f and 77f for optimal results?So nothing growing yet, right?

its good now for germination. no fans are on yeti m a bit worried with your RH wich is a bit high and may expose you to mold near the end of flowering, it may drop in a few weeksdepending season and the weather but keep monitoring the rh for a whole years to know what's average
it's preferable to have a lower rh than high to prevent mold
if it happen 60% is your standard everyday rh you may want to look if a dehumidifier could be efficient enough inside your shed.
ok, ill see how itll look like later then fix itfrom my experience rh won't change much with fan and extractor on, even once the plants will be big enough rh will be higher iniside the tent than the shed especially at night
i have grown a few purple.

but nothing like blue.
my friend had a few phenotypes from tropicana poison f1 fast version with leaves turning close to black near the end of flowering.
