Yup that's essentially what I ended up doing. Then I used a little chart I have to figure out the best size screw to use to secure the pieces together, used silicone in the corners of the channels to keep the plastic sheeting stuck to the sides and bottom, and stapled the plastic to the plywood channels above the water line. Then I had to use a 6" hole saw to carefully drill out the holes in the lid piece, and painted them all white with Killz.

The best part is if the plastic wears out or gets a leak in it, it's easy and cheap to replace. I think when I was building this I priced channels that were made of PVC and similar dimensions, but they wanted like over 100 bucks per channel. I made 6 of them this way and only spent like 50 bucks on plastic, silicone and staples. Already had the plywood on hand as I said.. My channels are approximately 8 feet long (the length of a sheet of plywood) about 8 inches deep and 8 inches wide and will hold 6 plants each.. If taken care of properly, should last me the rest of my life.

Oh, and I found a plastic tote made to store fake Christmas trees at Walmart during the holiday season as a reservoir. I just lined the outside of it with panda plastic as it's a clear tote. Works great as a reservoir. It's not too tall, nice and wide so all the channels can just gravity drain directly into the res. Holds about 50-60 gallons or so.

Definitely a great thing to build but I guess he should way the cost and time to build against suing this type of grow once or multiple times. If he wants to do it like this again then definitely this way but if he wants to change it maybe just the sprayer this time around but it would be good to have it on hand if needed. That tote sounds perfect, just needs a decent submersible water pump and some hose, air pump&stone and he’s golden

I just noticed this but you've got a lot of room left in those solo cups - maybe once the plants get a little bigger you could pop them out of those cups and add some fresh dirt at the bottom and put the plants back in? Just a thought.
