Compatibility: This growth sponge is compatible with popular hydroponic systems such as Awesome Plant indoor hydroponic garden, AeroGarden, iDOO hydroponic, and other hydroponic planting systems. 2. Shape and Size: Square shaped, with dimensions of approximately 1.1 * 1.2 * 0.8 inches (2.8 * 3 * 2.1cm) before soaking in water, and approximately 1.3 * 1.4 * 1.1 inches (3.3 * 3.6 * 2.8cm) after soaking in water. 3. Planting hole style: planting hole style and incision style (this is the planting hole style). 4. Matrix composition and storage: Made of peat and coconut skin, loose and breathable. The unique microporous ventilation structure design increases the water and fertilizer retention ability of the sponge, balancing oxygen and moisture. The growing sponge is dried before leaving the factory and stored in a dry place. 5. Usage steps: 1. Soak the sponge thoroughly in water for about 3-5 minutes. 2. Place the seeds in the planting holes. 3. Place the sponge into the square planting basket. 4. Put them all into the hydroponic system.

These work well for starting seeds.

Not compatible with Gardyn. They are the correct size but are too dense to allow roots through them.

I like these growing sponge cubes. They fit in a seed tray and they also have a pretty deep hole for placing the seed or cutting in the sponge. I have been using them for my blackberry and raspberry cuttings and I did use a knife to made the hole deeper to accommodate the cuttings. These sponges are really good quality and I think that they are a great alternative to other kinds of germinating mediums, like soil mixes. So much less messy and the sponges are inert, so there is less chance of introducing pathogens while the baby plants are growing.

I grew butter squash in these cubes. Butter squash seeds are kind of big, so it fit perfectly in these cubes. Soak these in water first for like 1 hour or so, then put seeds in, and let it sit in net cup with water touching the base, not flooding the seeds, then cover it if the temperature is too low not suitable for starting seedling. Covering the the cubes with plastic or something to keep it warmer, the seed will germinate faster.These cubes are good size, so it's good for initial roots to start strong to keep the plant sitting stable in the cube, other small cube will probably tilt the plant.Watch out for the cost of these cubes, it could be pricy and not worth it, however if you see a good deal for large quantity or if need be for your valuable plant then it's fine. Because you can use regular potting mix to start seedling then transplant it directly into a net cup without these cubes but you will have weaker plant not standing up or will tilt, with these cubes it will stay up.

These hydroponic seed pod cubes are a little larger than I had expected- about 1.5 inch cubes. They don't fit my narrow hydroponic seed starters, but they do fit nicely in standard starting trays (like the six packs you buy at Walmart). The material they are made from is an absorbent spongy material with an indentation in each one for seed placement, and they hold moisture well for germination. Once the roots get established, you just lift them out and plant the entire thing in the ground- plant, sponge and all. It prevents root damage during transplanting and the sponges eventually biodegrade into the soil.
