Understood. They look real sturdy and the lip looks large. Also a 6" hole saw with arbor and pilot bit is half the price of a 5 1/4" or 5 1/2" hole saw just by itself; trying to save money here and there when I can. All of this adds up real quick! Got 90% of it on the way, can't wait to get started. Thanks again for sharing your experience and making this great tutorial available to us all.

This is a great system. Finally able to fill my tent. Using a Supercloset Superponics system before, trying to grow 2 to 3 plants in 1 reservoir. Worked ok, but 1 plant always did well while other stunted. Finally decided to grow just 1 plant in old system, and had fantastic results. Now have a 4 bucket RDWC system, built from Hesienbubble videos, and have 4 fantastic plants.

One thing to be careful of, buckets I purchased were square black from Amazon (10 for $95.00). These buckets seem to be brittle, for lack of a better term. I did not get whole for one of the bulkhead fittings cut very well, leaked at fitting. I fixed the problem by cranking the fitting extremely tight. This worked for about a week until bucket cracked at the fitting.
Not sure if buckets are too thin, or I just screwed whole for bulkhead fitting up. Either way, make sure your wholes for your fittings are cut well. Second system built works great, no leaks. Found a great tool to shave the whole to fit. Have a pipe cutter that has an attachment for shaving PVC. Works better than a razor knife for me.

Do you run straight RO water and add this along with nutes, or do you buffer your RO somehow? I'm new to hydro and was reading up on it, saw some people suggest adding tap water to RO at 20% to buffer...sounds counter-intuitive?

That recipe is for benny tea. The tea can't have any chlorine in the mix or it will harm the herd.
Adding tap to RO is to aid in stabilizing a feed water regimen. Straight RO can make your pH drift with certain nutrients. Adding tap helps to buffer the final solution against pH changes.

Thanks for that. So basically in the reservoir, put RO water with Benny tea and nutes, check ph and ppm, then run through the system? My tap water smells a bit like chlorine so if I add it back in the mix won't it mess things up? How do I filter out the chlorine without runnong it through the RO system?

@Heisenbeans how did you get free shipping through ULINE? I tried different options and still got charged (and it's a lot since they use freight and not ground)

Thanks I'll check into that. Got any amazon links? So everything else I mentioned above is in good order?

Yes, looks good, but if you're running bennies and you want to use tap water you either need to treat it with potassium metabisulfite (1/8 tsp/gallon) or filter it out. I dont know what size your filter system is, but the one below will fit a "small boy". Here are the requested links:

The gac filter link you gave me - is there one that has a housing that can fit straight off the hose (thinking of doing the tee-off so I can add chlorine filtered tap back into the RO water to buffer it)

I'm sure you could find one, but what you already have will work fine. Just tee off the line between stage 2 and 3 to get GAC filtered water. I would not recommend using the mineral add-back stage. As that stage depletes your pH will drift.

I have had buckets crack because wholes were not cut correctly. I have a plastic shaving tool that is attached to a pipe cutter. makes it easy to enlarge whole and keep it round. Bulkhead should fit snugly, should not have to be forced through the whole.
It will be a long grow if your bucket springs a leak in the middle flower. Hard to change bucket out when plants fill the tent. I had to change out towels twice a day, and went through a bunch of extra nutes.
I used a razor knife to shave off some of the hole to make it a tad larger. The bulkheads should go in without any issue.

I used a razor and made the holes bigger. It was more cutting than I thought I would have to do. They fit snug and made a noise when pushing past the threads. These ULINE buckets are pretty tough. One bows in a bit still but the nut is on pretty good. The holes aren't perfectly round and a tiny bit jagged. Hopefully they won't leak. Still have room to tighten nuts a bit more. Do I need to do a test run to see leaks or should I just hand fill each bucket with water?

I would definitely do a test run, use just enough water to cover bulkhead fittings and have the pump pushing water through the system. My first build buckets held water with no pump. Had small leak when I started moving water through system, possibly from moving while assembled. Lot easier to fix if not having to deal with plants and trying to work in my tent.

If you have any leaky hose fittings, teflon tape can help too. Just wrap it around the male end and then screw the female end onto it.
