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.

Please try!

I love this product! It is SO much better quality that normal potting soil, my plants really appreciate this as a base! (I also use perlite, orchid bark, and am trying out worm castings with my next batch.) I have NOT had any mold appear, and I had it contained in a blue storage tote for around two months. (I would occasionally remove the lid to let it "breathe.") This looks just like soil after it's been moistened! I definitely recommend these coco coir bricks over a bag any day! Please note! These bricks DO take a hot minute to break down, I had to add more water two or three times before majority of the chunks were broken down.

Great product

I use this to combine with my potting soil mix according to how much moisture I need for different plants (and I have many). It's economical and easy to crumble and mix in-a very good buy and compact for my work space.

Great size and easy to use.

The small brick size has been easy to rehydrate (just over 3 qts of water worked just right for me) and mix with my other potting soil ingredients. It rehydrates quickly and breaks apart easily once it’s soaked up all the water.

Good product

Great product. I placed it into a container and filled with the desired water amount. In a matter of minutes it was absorbing and able to be mixed in two our beds. So far so good as it does not seem to cause any drainage or excessive water retention.

Shrinkflation is Real

I purchased these last year and was very happy with what I got. The product itself is great added to garden soil instead of using peat moss which is both expensive and becoming a rare and irreplaceable product. Unfortunately, this year’s purchase of the blocks was a bit disappointing. For a higher price I got smaller blocks (probably half the size as the previous year. I will know for sure when I soak them. Last year’s blocks once hydrated easily filled a five gallon bucket. Don’t see how these small blocks will do the same.
