Description

Grow sponges are soilless growing mediums that ensure seeds have just the right environment for germinating. They do so by providing the seeds with adequate amounts of oxygen and water and causing them to sprout. Can I Really Start Seeds in a Sponge? Not only can you really start seeds in a sponge, but grow sponges are considered one of the most successful ways to start seeds. When it comes to hydroponics, there is no better method for starting seeds than using a grow sponge.

  • Seed starter sponges
Size: 0.98" × 1.1"
These little cubes worked fine for me for starting my lettuce and kale seeds. I soaked them for an hour and then put them in a seed holder with water tray and you can see the results.

  • Reccommended
Size: 0.98" × 1.1"
These work great and they are biodegradable, unlike the sponges that most of the growing systems come with.

  • Not so good
Size: 0.98" × 1.1"
Bought two different kinds at the same time. The others worked much better.

  • TINY. WILL NOT REPURCHASE
Size: 0.98" × 1.1"
IMAGE AND DESCRIPTION NOT ACCURATE. TINY. Much smaller than expected. NOT SQUARE, more of a triangle with very small bottom, so they fall over even in tiny cubes because so much smaller than the cube. Will not repurchase.

  • Great Quality Hydroponic Grow Sponges
Size: 0.88''× 2.48''
I really enjoy growing vegetables and other plants hydroponically. I go through a lot of grow sponges, and so this set of 100 pack is a great value. These grow sponges are 2.5 inches and have a pretty deep seed hole, which could also be used for cuttings as well. They have good porosity and water retention. I just got a 50 space hydroponic grower, so I am excited to try these sponges. ... show more

  • Too small

These are tiny should have read the ad better about 1/3 the size I normally get .

  • Standard Quality
Size: 0.88''× 2.48''
If you like this type of grow sponges, you won't be disappointed with these. They are similar to any others I have used. With a bag of 100, I have enough to last a long long time. I use a sharp awl to cut through the sponges from top to bottom without having them fall apart. It gives the seeds a much easier path for their roots. ... show more

  • Good but would rather they came as a perforated sheet
Size: 0.98" × 1.1"
Single sponges definitely work well but it’s a lot of moving pieces. It’s be lovely if they came as a perforated sheet.
