Fresh air or max insulation

Do you guys have fresh air coming into your grow room or do you think I shouldn’t add holes into my commercial grow to have fresh air coming in and work on instead maintaining temps, humidity and pests (hopefully none!)

let me know your thoughts!

This is for a commercial-esque 800 square feet grow that is a “proof of concent”. Will be adding a 10,000 square foot room next year if I can prove sustainable profits in this, but the one requirement is, everything has to be similar to the large grow on this one (investors want to know for sure it’ll work in the bigger one).

I run fresh air into my grow room and I either have a hepa filter or carbon filter with a less cfm fan then my exhaust no bugs no viruses nada but then again I run my indoor grow or grows during winter and use the cold outside air like my ac would in the summer. It’s a bitch where I live to try and battle the heat and humidity during the summer and it’s still illegal so not trying to put in a split ac in would draw to much attention so I start my outdoor season gorilla grow plants indoors for just about 2 months then outside they go and become hudge monsters

Fresh air. One of the reasons plants grow bugger outdoors.

Talk to RENFROE if he's online. Smartest commercial grower I've come across on RIU, dude is so good he could charge folks for grow room design and setups.

If you enjoy fighting pests, ventilate. If you want to constantly be chasing temps and RH, ventilate. If you think inconsistent growing conditions are the way to great yields, ventilate.

When you're ready for a rock solid solution, talk to me.

Please explain further.

I currently have a 4 x 8 with an AC 6" AC infinity fan and carbon filter exhausting straight out of a window and a 6" vivosun intake fan bringing in fresh air from outside via a window. Am I doing something wrong? Temps are steady 75-80 and RH is 50.

Was wondering if I needed to exhaust or if I could just leave it a completely enclosed system (which is what I planned on doing) and add an intake since plants do make use of Oxygen as well albeit to a very small amount. Since I was going to run such a high density of plants I thought maybe I should allow show free air in as well.

Just make sure you have adequate dehumidification and cooling (dehu adds a lot of heat). High plant density can become an issue when the biomass reaches a critical mass so to speak the dehu can't keep up and youre fucked. In that case an intake could help provided you have cold dry air outside but thats the only case that an intake would be required IMO is if you don't have the dehumidification required for the intended biomass. It's not an ideal solution as the ambient temp and RH% are a variable. Here in colorado, high desert conditions, running at night, I can use intake air to help with humidity but the CO2 enrichment is cut off when that happens, so again, not ideal.

Have a Dri-Eaz 7000xl that we had from some prior work. Was looking into adding a Quest 2-series as well, would more be necessary?

Only one way to find out.

TBH it's all about the amount of biomass vs the amount of dehumidification potential. If you are pushing the limits then you will end up wanting to avoid any cool down when the lights go out to prevent a rh% spike. Cool air holds less h2o therefore the RH% rises as the air cools provided the actual amount of water stays the same.

Roger, was going to turn the dehumidifiers on at “night” but I’m not sure if that’s enough. Hopefully the pulse doesn’t lie to me :P

This is a great way to explain a confusing concept. Well done!
