What's up AFN
I've taken on building a grow room. It's been a few months in design/plan/implement and despite careful planning I have run into an issue I did not expect.. heat.
The setup:
Space: 5'x9' Gorilla tent (I have light leaking out of corners, my first tent and there are tiny, tiny beads of light but if you get up close you can spy right through them and see inside.. not sure thats normal.... could seal it but anyway...not the matter at hand...)
Lights: 2x ViparSpectra 600 Reflector series
- i am only using half the tent as I realize there is a learning curve on the botany side too. I'll add as I go... or grow.. as it were...
Ventilation:
Intake: 6" iPower 440 CFM sucking through an 8" ducted hepa filter box. This comes in through the bottom- front- right and has a cheap 16" oscillating stand fan positioned inside, in front of the incoming air to move it throughout the space.
Extraction: 6" iPower 440 CFM with carbon filter. This is positioned top left of the tent, fan outsode the tent, 12" of flex duct to the carbon filter which is inside and level with the duct.
I'm using 2 sensors, an Accurite attached to one of the lights and an Inkbird probe that's attached to a controller. They match or fall within .x° so I am sure the temp is accurate.
This is all in a basement. The ambient temp is 77°F. - I think this has to do with me having sealed the basement with plastic sheeting over the insulation to prevent dust. Its likely the most well insulated room of the house now... had monitored it for over a week at 75° prior to the sealing.
And now for the problem:
My interior temps are at 83°F which is cause for concern considering... the tent is only half lit. If I added another light now I would probably see over 85° and as it is my first grow, I haven't got a cO2 system meaning that heat is bad news.
So, I think my answer here is probably simple and to add an air conditioner to the space - and if possible, duct intake to that and set a large stack boot there so all my intake is coming off the AC.
What do you think? Could it be I specced the fans too low? That is my biggest concern I guess. I don't want to be running the wrong gear and therefore fixing the wrong issue.
I am able to get negative or positive air flow quickly (balloon the entire tent outwards and inwards in under a minute or so by adjusting intake speed), so I am leaning toward.. overall environment? The intake air is not cool enough to dissipate the heat?
Is a +5°F in the space to be expected regardless of air flow... or should I be able to obtain a temp closer to the intake temp?
