My inline fan with had 6″ opening (28 square inches) so I would need 56 square inch opening. I went with two louvered grills that were 5″ x 8″ which gave me 80 square inches – 30% for the louvers = 56 square inches. Perfect!
“1st time grower. Plants are 1 month old, and 12″ tall now. Set up for less than $250. Used cab.w/4 bulb, 24″ T5’s, 4″ elec exhaust, Thanx for great info.”
The first thing to deal with was the Intake and exhaust – a clean environment and fresh air for my plants.
Now that my fan room was set up, I allowed the exhaust to escape upward into a carbon filter. I mounted the filter inside a Rubbermaid tote to make the whole setup more discrete.
Then reality set in: I have a small space, in a small house, in a crowded neighborhood.
This allowed three different height settings for the light. The unused two positions are capped off. Take a look…
Also, I installed a “Kill-a-Watt” device to monitor my electrical usage so I can easily calculate the total extra cost to my electricity bill each month.
A fan speed controller and light timer are mounted on the outside of the fan room.
After the initial investment, $1.64 was my total cost per gram when I factored electricity, carbon filter, and nutrients.
