【400 pcs】 Hydroponic Seedling Sponge - Black Type

Hydroponic supplies.
Seedling starter sponge x400 pieces, black type.
Comes in 10 sets of 40 pieces each, vacuum-sealed.
Each piece is 2.5cm square with a pre-cut slit.
We also offer white sponges, but their performance and properties are the same. If you plan to transfer to hydroton later, the black color will be less noticeable.
After purchase, they are vacuum-sealed and stored with the air removed! Just like a futon, they will return to their original size when opened.
I've also included photos of vegetables grown with white sponges in my home.
We grow lettuce, sunny lettuce, leaf lettuce, mizuna, komatsuna, baby bok choy, baby shungiku, baby spinach, and more.
We recommend managing the seeds together until the roots emerge from the sponge, then transferring them to pots and growing them with liquid fertilizer.
The combination of powdered Hyponex and Menadione is the most effective for smooth growth.
These are new and unused, but they are not pure white. Please refrain from purchasing if you are concerned about this.
I use them myself, and I use ones that are deformed or dull. Due to compression, the ones you receive will not be in a connected 10x10 grid!

We have more available, so please comment with the quantity you desire, and I will adjust the price and list them.
We also offer soil-type products and pots.
