200-400w DIY DWC Grow

The setup is as follows..

Genetics are 1x Flash Babylon, 1x Chocmatic, and 1x Pakistan Ryder, all autoflower and feminized.

I don't know much about these stains. I was shopping around for specific medicinal qualities and came across the Ryder. I bought a 3 pack and the other 2 were the freebies (thanks Dr. Chronic). I decided to go for 1 of the ones I had picked and the freebies on a whim because they sound nice lol.

The light is a 400w dimmable HPS. It can be dimmed to 75 and 50%.

Air pump is 3.5w dual outlet with a 2 and 5 inch hydronics air stone. Difference in size is because I bought them separately and I forgot which one I had gotten the first time. Might go get another 5 inch one.

Seeds were planted in 4 inch net pots with a Coco fiber medium. The container is a 14 gallon storage tote, water level is about 2 inches below the net pots.

I don't know the exact growing space, but I know it's more than enough for my needs. I'm trying to grow approximately a half ounce per week. With each seed at around 9 weeks to harvest (reportedly), plus an additional 4 weeks to cure, that makes my overall goal about 6 and a half ounces.

The grow room is in a large basement closet with the only ventilation being a rather large gap under the door with an oscillating fan to move the air. I'm not worried about light leaks as I plan on running the lights 24/0 to maximize growth.

My hope is the location and size of the room will prevent the need to cut a hole in the concrete board. I had the light dimmed down to 50% for the first 36 hours and the temperature didn't get above 60. I turned it up to 100% and will check on it every 4 hours until I'm comfortable it won't get hot.

I'm posting this because my previous 2 (failed) grows have gotten me kind of discouraged. The first one I cooked the plants with the same 400w HPS in a much smaller grow room (think stealth cab), and the second one ended up getting pollinated and I got mad and ripped them up.
