Baaically i covered the backside of a 5.5" usb fan with a stockings bag filled with activated carbon and about 200g of it.

I think 200g is too much as it makes for about 1/2 inch layer and i think the sucktion is little to none.

I am considering taking off some 100g of the 1-2mm coal and making two of these.

I hestitate to pick this one apart and wanted to ask what a good test would be and how much suction i need.

The space i ventilate is 1x1x2ft, micro

The design was good i think.
I removed about 100g and got barely enough pull for smoke to get in.

I think one or two of these will be enough and the noise is negligible or easy to mask.

I will try to make an exhaust silencer box on the inside.
Here is my box

I use top drawer for exhaust, currently it's a rather loud shoedrier blowing out air without heating it. Passive intake from the bottom.

2nd drawer has 9 led lightbulbs, 10.5k lumens.

Plants are 3-4th drawer, 4th or 5th drawer about a gallon of soil and 6th is the electric wiring.

It is my first grow in there now, just saw what i think is preflower on 2 females today and 1 male plant. Screenshot_20210226-205712_Gallery.jpg
I could've had a 4th plant.

i made a big mistake starting to train them late in week 3, lost some good leaves, switched to 12-12 after 2 weeks.

I think that if i clone the best cultivar and start bending before the 4th node on 24 light then i could've bent them around the edges of their pots and then top after 3 weeks.

They would've filled out the whole thing and it might work i think.

I hope for 30-50g now and on the next run.

Sorry to say, but those plants need some help. They look really sad.
