How much to fill 5 gal bucket?

A standard five-gallon bucket actually has a total capacity of a bit more than five US gallons - approximately 5.75 gallons, if I'm remembering correctly. If you fully hydrate/expand two of the blocks, you will have just a small amount left over after filling your bucket to the brim. Expect to get approximately three US gallons per expanded block. Remember that composed coco coir - rinsed or not - will still contain a lot of sodium and potassium ions in it. After hydrating, it's a good idea to *fully* rinse it; the best way to do that is to SLOWLY dribble water through it for 24 hours. Regardless of whether you rinse it properly or merely put some into an old pillowcase and run water through it at a high rate with the garden hose for 20 minutes... After rinsing, allow it to drain (you can squeeze the pillowcase or whatever it's now in to remove additional water, but leave it good and damp), you'll want to replace those ions with calcium and a bit of magnesium. You can soak it for an hour in a weak solution of calcium nitrate with some Epsom salt added (both are inexpensive and easy to find), or you can buy a commercial "calcium + magnesium" product if you feel you have too much money. Afterwards, your product will be ready to use and will not "steal" Ca/Mg ions from your nutrient solution - as long as you do not allow your coco to dry out from the time you begin using it until harvest. REMEMBER: You can grow a substantial plant in a small volume of coco, and it is better to use a smaller container and water several times per day with nutrient solution than to use a larger container and only do so once per day; this is passive hydroponics, after all, meaning the only replenishment of dissolved oxygen in the root zone is by you replacing the nutrient solution with a fresh batch.

How much soil does this make?

one brick will take over one gallon of water to expand and one brick will make about3 gallons of fiber. I usually mix it with a good potting soil.

Is there any fertilizer in it?

It is nutrient sterile. I made that mistake in the spring when seeding the summer vegetable garden. You need to add fertilizer such as rendered fish waste.

Right here in USA. That's where it came from but where it was made is not given on the information page included with the bars.

Favorite tortoise bedding

I’ve never used for plants but have read plenty enough that if I were to plant I would use. I have recommended this kind and use this kind when I am buying to have extra bedding on hand for my baby sulcatas. Seems to hold moisture pretty well. Easy to mix and use.

Good product

This is a good product and is great in my seed starting mix, but I will say this is definitely more difficult to use than the ready made stuff. That’s kind of a given, but it’s definitely added a lot of time to my process because I don’t need the whole brick. I broke off some smaller bits (difficult to do) because I really didn’t want to get the whole thing wet if I’m not using it. If you have a larger project then I don’t think you’ll have as much of an issue, but it’s still a chore to try to get it all to soften. It’s not instant. It’s a space saver though and also more cost effective.

Does not hydrate, too fibrous

This coco coir does not hydrate and is extremely fibrous. If you follow the instructions and put a brick in 4-5 quarts of warm water nothing happens. You have to break it up before you hydrate and then keep it in the water for 24+ hours. Even then you will be working it by hand because ZeeDix does not break the husks down very much. This is not a fine pulp, it is still fibrous. If you go through the effort of breaking it down so it will go into seedling trays it still does not absorb much water. With other brands I have to really squeeze the coco coir to get the water out. With ZeeDix it does not absorb any water so you just squeeze it once and you are done. This might sound like a plus but it is not. You can feel how rough it is as you mix in the perlite and vermiculite. Buy another brand and save yourself the hassle. The people giving this 5 starts must have never used another brand of coco coir.
