Background:As I'm designing my stealth Rubbermaid tote aeroponics system(2-3 totes stacked on top of each other).Stacked on top of each other. Bottom tote is the Reservoir/aeroponics spray area. Second tote is the first grow area, with the scrog screen and lights on the lid.Then when the plants hit the screen and its ready to flower. I plan on putting another spacer tote in for flowering.
Idea:I'm working out the ventilation. I will have the exhaust air coming out of the top of the unit(2-4 80mm PC fans I have). I was thinking it would be a good idea to actually draw the intake air from the reservoir tote(passive intake slots in the Res) to keep fresh oxygen flowing into the reservoir water. I worked out all the kinks as far as keeping light out of the Reservoir and keeping water from spraying up into the grow area and/or out of the tote onto the floor.
Question:If I draw all the air coming into the system from the aeroponic spray area. Do you believe I will have a PROBLEM with EXCESSIVE humidity?I keep thinking that if I don't introduce humidity to the system I wont be able to get it high enough via any other means.Its winter, its cold, heat is on, its dry. I **think** I will have to exhaust too much air to keep the temps down with 12 26w CFL in a 18gallon tote space (20"x16") to keep humidity up other ways. The other benefit routing the intake air via the reservoir is it will be a lot cleaner and easier to keep the intakes light proof. However if those with experience tell me I will have bad side effects from doing it I will have to find another way. Possibly make one intake not in the reservoir and one IN the reservoir and make it so I can regulate how much air is brought in via the reservoir thus control my humidity a little bit. I just rather not have to make an intake inside the grow area tote. keeping it light proof is usually ugly and not very stealthy. I don't have a lot of grow area so I don't want to cut into it any more than I have to.
I DO understand this will also create a lot of evaporation of the reservoir water. I'm prepared for that. It will also keep the reservoir water temp dead at ambient (60-70) roughly.Any input on the matter is appreciated!

.. You're right about having to exhaust too much air to keep RH up, especially with 12 cfl's in that tight space. There going to want it dry come flowering time, that = more thc, so till then i say just mist them often, or maybe even setup one of those habba mister units to do it for you.
