Oh BTW... my next QUESTION:
So my tent has a ~4" x 7" opening with a screen (I can post a pic if there is interest) at the bottom of both sides of it. It also has holes for running ducts out both sides as well. For my passive intake do you think opening both the screened openings will suffice or should I do a short run of the duct on both sides?
How much light is in the room when the tent is sealed up and in dark period?
How big is the room the tent is in? Are you exhausting in the room the tent is in? If so What's the air exchange like in that room?
Intake should be bigger then exhaust. 6" exhaust 8" intake.
Your fan would perform best attached to the filter.
*active intake. If you have a sealed tent and using a fan on the exhaust, then it's also pulling air in.
Height shouldn't be an issue when running scrog in a tent that's five feet tall.
2 plants would yield more, your veg time will be longer but you'll have a greater root mass which supports bigger yield.
I'd go with one scrog net.
If you focus on yield too much you're likely gonna have more issues. My buds are growing slow, maybe I'll add this and that or what's this lil bit of yellow on my leaf I need this or maybe this.. these are some examples of wanting to do more..etc
But you'll end up reducing yield and creating problems.
If it's your first grow, my advice would be to observe, take notes, be patience, when you feel like you wanna do more (Cause you will!) Grab a book and read while hanging out with your plants. Something like how plants work.
this is all IMO
