Top chamber is about 2.4 feet high, bottom is about 1.8 feet.
2 exhaust fans each chamber and has one inlet fan at the bottom as in pics 1, 2 and 3. All fans are 80 mm PC fans. I selected the ones with less noise but good airflow.. but airflow is not enough I think. Plants appear to have heat stress.. pics 4, 5.
I want to use bottom chamber for veg and cloning (currently it is not used).
However the CFLs take top 5 inches of each. The tall plant is getting heat burn.
1. Can the heat burn be reversed?
2. how to fix the growbox design to reduce heat?
3. At some point I will need carbon filters. How to install them?
4. I am thinking of putting two fans inline at exhaust. (making 4 exhaust each chamber)
something like
[outside] <--- air --- fan1 | flat carbon filter | fan2 <--- air---- [inside]
Will this work?
Thanks in advance
