Premium Grow Sponges - 100 Pack Replacement Root Growth Sponges for Hydroponic Seedling Starter Kit

Grow sponges are soilless growing mediums that ensure seeds have just the right environment for germinating. By providing the seeds with adequate amounts of oxygen and water, they cause them to sprout. Not only can you really start seeds in a sponge, but grow sponges are considered one of the most successful ways to do so when it comes to hydroponics.

When it comes to the size selection of planting pots, grow sponges are perfectly compatible with LAPOND square and round planting pots. For other planting pots, please refer to the size of the grow sponges to ensure compatibility. The dry dimensions of the grow sponges are as follows: top length - 20mm/0.79 in, height - 23mm/0.9in, bottom length - 14.5mm/0.57in, hole diameter - 3.4mm/0.13in, and hole depth - 4.7mm/0.18in. After absorption, the dimensions change to: top length - 25mm/0.98in, height - 29mm/1.14in, bottom length - 18mm/0.7in, hole diameter - 5mm/0.2in, and hole depth - 6mm/0.24in.

These grow sponges are compatible with most hydroponic growing systems and are widely used for hydroponic, seed starting, cuttings, and plant propagation purposes. They are great for both gardening hobbies and commercial hydroponics supplies. However, it is important to verify the dimensions before purchasing to ensure compatibility with your specific application.

The grow sponges are made of pure natural peat, which is very suitable for helping with germination. The seedlings after rooting are easily transplanted into soil or any other medium. You will receive a pack of 100 replacement grow sponges, which is enough to start hydroponic planting of multiple plants at the same time, saving you a significant amount of time.

These grow sponges are suitable for the growth of many plants, including strawberries, tomatoes, peppers, cilantro, basil, and flowers. They provide a soil-free and mess-free environment, allowing you to enjoy the spring-like experience all year round.

To use the grow sponges, simply soak them for about 2 minutes, place the seeds in the holes, and then put the sponges in the square planting baskets. Finally, put the entire setup in the hydroponic system and wait for the seeds to start growing.
