Which would produce more DO in a DWC?

A clothes iron on low heat can form a flat on the side of the bucket. Have a towel with cool water to set it once it's flat. IDK if the fittings will still fit if you flatten out the buckets you already drilled, the holes might go oblong during the forming.

Nevermind... Didn't read to the end before posting.

I see where you're going with this. If I had stuck with buckets I probably would've tried this.

The totes (well mine) are not square so it's tough to get a real accurate volume, that's why I just take off a couple of gallons from total capacity, I never fill to the top to allow for more waterfall effect. Also I never actually measure other than use a clear container with 50 ml marks to add nutes.

I believe stated volume is usually 2-3" below the rim, but I'm sure it varies by manufacturer. The larger the tote, the less accuracy you need on volume. An extra litre in 10 gals isn't going to effect as much as being a litre off in 3 gals.

There's online calculators that'll figure out volume of odd shapes if you really want to get accurate. The taper on those totes doesn't effect it enough to worry.

Guessing got me close on my pH/nutes :-)

Gotcha. The reason I was asking about total gallons is because the 5-gallon buckets from the hardware store are actually around 6-gallons, to the rim.

I had square white buckets that kitty litter came in, they were awesome, but low quality and the plastic started breaking down under the lights. I really wish square buckets were more commonly available, it's always surprised me they weren't the standard in hydro.

Stupid round buckets wasting space. :finger:

I hope the ones I have (used for syrup) don't do that :(. I'm going to try 2 at a time and stagger them by 3-4 weeks and try to get an in and out cycle going.

5gal is usually measured at the first molded ring around the top, from the bottom. Usually around where the handle is mounted.

Before I knew this I went F'ing nuts trying to figure out why 5gal buckets ands 5 gal nursery pots didn't hold the same volumes.

I hear ya. I was going to look for litter buckets. But after what you mentioned, about the plastic breaking down, I'm glad I didn't. Probably breaking down from UV.

I was really surprised to find that the square hydro buckets weren't more available. I really wanted to use those, but the only ones I ever found were around $16 for a bucket and lid. I find it difficult to pony-up lots of money on square containers.

I really like the hdx containers!

You may be able to treat the buckets. If it were me, I think I would take some car wax or sealant, like Nu Finish, and add a layer or two.

Same thing threw me off when looking at 5-gallon root bags. They looked more like 3-gallon bags.

Don't you have design software? Can it figure volumes for the objects you've created in it? I used to work with Solidworks and it could figure out all that. Tell it what material and you'd get weight, mass, volume, etc, etc. I need to go find a newer copy and practice, it's been years since I've used it.

I work (play) in 3ds Max 2017, Sketchup Pro, and have worked in Maya as well. But that's just a hobby. I was a contract programmer/database developer, after I got out of the Army in '94.

I haven't had a need to play with any volume calculations, or anything like that. But I'd have to imagine someone's got a script for tools like that in 3ds Max. There are scripts for pretty much anything related to physics.

My AutoCAD does it but really is it necessary and honestly it would take less time to measure the water lol.
