They were perfect and worked so well with my seeds. My plants has sprouted within 3 days of placing them in the soil. The package was delivered quickly which was great because as a garden girly I was too excited to start a new round of plants!

  • Great pods.
Size: 50pcs sponge
Works great. Seem to be a little more compact than other pods I’ve used in the past but didn’t stop the roots from growing and made transplanting easier.

  • Mold grower
Size: 50pcs sponge
Just grows mold on every single one and kills seedling systematically. Very bad quality. They aren't even the same size. A lot are way too short. Nothing has managed to grow. Waste of money.

  • Not good quality
Size: 50pcs sponge
These were not the same quality sponges that I received with my original grow kit. They crumble and fall apart and I have not had a good success rate for growth with these. Will not buy again. Would not recommend.
