Reddit mentions of Tinker3D Antminer S7 S9 S9i E3 T9 L3+ D3 A3 V9 X3 120mm Fan Duct Cooling Shroud to 4 Inch Vent Hose

Container: Rubbermaid 20 gal Brute Bin

Lights: Kingbrite 60 W Quantum Board (if you want dimmable, ask for a dimmable driver like the HLG-60H-36B and a potentiometer)

Screws: You'll need lots of nuts, long screws, washers, and spacers to mount the board and PSU. First put the board on the lid and mark where to drill, then drill holes. Then put the power supply on the outside in the middle, mark and drill those hoses. Mount power supply and then flip lid over and mount the light, using long screws and nuts to hold it in place (the light should NOT touch the lid but be 1-2 inches from it, held in place by nuts). Drill small hole for power line, then connect. Finally, drill 3 inch hole for exhaust beside the light. You'll also need long screws with nuts to keep the fan and shrouds together. Be sure to use spaces anywhere the screw heads or nuts are touching the lid or the lights. For light spacers, I used rubber spaces between the nuts.

2x ABS fan elbow (for "snout" intake): 3 in. ABS DWV 90-Degree Hub x Hub Long-Turn Elbow

Air filter (not pictured): VIVOSUN 4 Inch Air Carbon Filter Odor Control with Australia Virgin Charcoal for Inline Fan

Fan hose (not pictured): iPower GLDUCT4X8C 4 inch 8 feet Non-Insulated Flex Air Aluminum Foil

Watering device (not pictured): Janolia Automatic Irrigation Kit, Self Watering System, with Electronic Water Timer

Camera (not pictured): Wyze Cam 1080p HD Indoor Wireless Smart Home Camera with Night Vision (glue steel piece for magnetic base onto the upper side of the bin)

Notes: This design is very safe because it keeps all electronic components high in the bin. At the same time, using a battery powered watering system keeps you from requiring to ever open it. The lamp runs very cool. The PWM fan controller works well and keeping the air moving without using a lot of power (do NOT buy a cheap voltage modulator, I did first and it doesn't work nearly as well as the PWM controller). The Wyze cam is super cheap and lets you keep an eye on everything or make timelapses. Have fun growing your tomatoes!

Not sure I gave the best description, and turns out I ordered from Amazon not Newegg. Below are the two essential components I used. I had some magnets I could use to mount the Fan to the back of the dryer from another project. All in all cost about $30.

If it has to be PVC, I don't really know.

You could use something like this if you use ducting instead.

I used a rubber coupler to attach the fan to the filter. The flexible ducting is clamped directly to the fan. On the other end, the spacebucket, I have a 4" x 120mm fan adapter that the flexible ducting is clamped to > https://www.amazon.ca/gp/product/B01LXZ8EUG/ref=ppx_yo_dt_b_asin_title_o04_s00?ie=UTF8&psc=1

Carbon filter eliminated nearly all odor. I went the first 3 or so weeks without it, then the smell started coming on strong as it was starting to preflower. Bought the filter and it was night and day. Highly suggest it.
