Hey Switch. I plan to start the bucket boilin' on the 19th. Start seeds on the 21. Put them in the OBBT sometime before the 27th.

Thanks for that article. I'll check it in a bit. Cool of you to post that. I generally like that stuff.

They do sell a cheap test kit to check levels in aquariums. Again that might take some of the fun out of it.
You guys have already done the work involved with this setup. I plan on eventually following what you have done, but first in order to understand it I have to make all the mistakes. It's my way of dealing with being a little slow in the head.
I'm thinking the ash used is chosen not so much for the amount of potassium left behind but rather for what isn't left behind. Burning simply gets rid of what we don't want. It cleans the potassium. A very clean ash would therefore suggest a higher concentration.
My main grow is outside. Being in a hot dry climate, I like growing in a pit rather than raised beds. It also makes it less obvious.
While I have pretty good soil, at 18" down it gets pretty sterile. It takes time to activate. It would be nice to speed up the process as well as have it replenish itself for the next grow. While mine isn't an OBBT grow, your threads, LL and DM as well, put the information I need in one spot.
Being in ground, with the leaching, my quantity of needed materials goes up. Cheapness as well as a desire to recycle my yard waste leads to using what I have. I also think to some extent that native plants while providing their own compost put into the soil what is needed by that particular soil. One has to be careful because some become to concentrated and become toxic to other plants hence my ghetto setup. I want to find out how many ways I can kill a cutting.

I'm testing the system at full air for a couple days. See what busts loose. Looking very sturdy so far. No leaks. Uniseals are great.

Is this possibly too much air? I have yet to lay down the volcanic rock.

This is 960 GPH into 6 air stones. Obviously the 1/4" airline and stones create some resistance. Not sure how much.

Here are a couple of images. Any thoughts before I proceed? I'm inclined to go with it as-is.

Jeeeeesus rrog!

Yea, uhhh, that looks like plenty of air mate, hahahaha!

I've never seen an OBBT suffer from low air-flow and it sure doesn't look like we're gonna find out from yours! I have no idea if that's actually too much, in theory too much flow is pretty hard to get. As long as your medium is super-spongey and doesn't bubble and froth as the air passes through it then there shouldn't be any problems.

This is kindof cool though, we'll get to see if there is any benefit to be had from massive air-flow through the tubs. Since you plan to set your rig up so similarly to mine it should be a good test. My money is on you seeing super-fast fungus development when you go to incubate your tubs, but I'm not sure you'll see much difference otherwise. But shit, who knows!? Looking good, keep it up buddy!

Well hell I'll give it a go then. Thanks for the opinion LadyL.

Rrog,
Where did you get the uniseals?
I just threaded fittings into the buckets with a washer and nut on the inside but I like yours better and I am going to make up 2 or 3 more for the next run.

Prices vary. These are really the way to go and are significantly better than threaded in my small scale tests. The curve of a bucket make these the best solution.

Thanks rrog. I am using kitty litter buckets so they are square but I still have small leaks so I want to pick up some uniseals.

Good luck. They kick ass!

For anybody else looking for them, I found the US distributor: https://www.aussieglobe.com/uniseal3.htm

The 1/2 inch are only 1.49 ea.
I ordered 15, shipping was $6
