are they only high in PH when you first get them or do they retain that high PH throughout their lives - should these be used in Aquaponics systems?

I can't answer your question directly but I will say that my aquaponic plants did not do as well with these as with other rockwool cubes. I wouldn't recommend them.

If they are not used and sit on the self they maintain the high pH. Once the seed germinates the pH level slowly decreases. The pH stays high easily past the point where the roots push through the bottom of the block. And yes, very good for Aquaponics systems.

That depends on many factors. I use 3 teaspoons in 1 gallon of water along with a few teaspoons of Aquashield to keep my water clean. After thats all mixed, I then use a meter to pH. I like to stay between 5.8 to 6.0 for hydroponic growing. Hope that helped :)

This is just my two cents worth. I suppose if you use enough of it, the pH of the soil could be raised. I base this on the fact that I use sea salt in my Cichlid fish tank to help raise the pH. However, since decomposing organic matter (like leaves and other composting matter) and many fertilizers lower the pH of the soil, it seems to me that the tendency of sea salt (such as Sea-90) to raise the pH cannot be a bad thing, assuming that you fertilize and include compost material in your garden.

The packaging states that the product is for use in container gardens or hydrogardening applications. My belief is that this is because the product changes the Ph of the water or soil to which it is added. If I add much of this to a hydro reservoir, I must then adjust the Ph and this might be challenging if we are talking about the soil in your yard. If Ph isn't a concern, I would think this product would be safe to use on outside ornamentals.

Yes no problem. Better use in fresh then salt. Will promote plant growth but not for any use in live corals

Yeah, I bought some of these at a fair one time and they had them in fish bowls. I do the same, with plants also, I just clean them regularly

I was having the same issue in a very well planted aquarium. I got a good test kit and found that the pH was too high and the water was too alkaline. So, I have been slowly adding substrate and driftwood pieces that will bring the pH down and used a water softener pillow. After about a week, I think I am seeing berries - no little ones yet, but I am very hopeful.

it won't throw ur ph off. what ever u have it on it doesn't drop or push ur ph at all. this is what i see from my grow. even in my hydro.

These are perennials. It will "grow" in the harsh PH but success rate depends on the soil and amount of true non evaporating moisture the plants get.

I still have a little bit of the black algae on a powerhead and a few rocks, but for the most part, it grows very, very slowly, so it doesn't get out of control to where the algae looks like somebody's hair waving in the breeze. As far as a can tell, it was actually changing the ph of my water which helped out there. I run a freshwater tank and try to keep the ph anywhere between 6.8 and 7.2 - obviously, if you are running salt water, that might be different, but where I live in Nebraska, the water tends to be quite hard and slightly alkaline, so I used an acid buffer. That's really what got the algae under control for me. I've heard some people have success with Flourish Excel in terms of keeping algae under control, but I don't think its really formulated so much for that as it is for overall plant health. Could be that it changes the ph slightly, and this causes the algae to die or inhibit its growth, but I don't think that is the case. If you want to control the algae, I would think that you need to lower the ph just a bit. It won't take much. That's been my experience.

These are the same grow sponges sold on AeroGarden's site, without the liquid nutrients. Their site says "AeroGarden Grow Sponges are made from pure Canadian Sphagnum Peat ..." I ordered these from Amazon because I have a large unopened bottle of the liquid nutrients.Some people have complained that the sponges fall through the seed starting platform. I simply soak them a bit and they fit fine.http://www.aerogarden.com/accessories/garden-starting/garden-starter-tray-refill-pack.html#moreinfo

You know, I've always simply assumed that they dissolved in the stomach...but for a definitive answer, I suggest contacting the manufacturer's customer service at gardenoflife.com and asking them directly.

I think they will last that long with no problems. I keep mine in a sealed bag and soak in a weak fertilizer solution before I use.

For us the became a part of our aquaponics set up. But they aren't what we were looking for. They go into a tube and water is passed thru them as a filter

I have stored them just like how they come and have had no problems. If they do dry out a bit you can rehydrate them with a little soak. I stored mine in the cupboard. Happy gardening!

Hey David did you end up planting these hydroponically? I am considering the same. Thanks!

Hi Pat, use them in both brackish and fresh so far so good yes I recommend them Great product!!!!!!!
