120 Pack Refill Sponges for the Original 60-cell Planting Block
Description / 120 Pack Refill Sponges for the Original 60-cell Planting Block
Your Bio Planting Block will last a lifetime with these handy, economical Bio Sponges. When you're ready to begin a new crop in the Planting Block, first be sure that the block has been thoroughly disinfected (warm water with a splash of bleach is fine). Then soak the Bio Sponges you intend to use in warm water for a few minutes. They expand, revealing the pre-drilled planting hole at one end. Simply slip one seed into the hole of each Bio Sponge, place the Sponge seed-side-up in the cell of the Planting Block, and you're on your way to another bumper crop of healthy, strong, super-quick seedlings.
Bio Sponges are comprised of a combination of coconut coir, peat moss, and bio char and are now enriched with oilseed extract, giving your seedlings an extra boost of nutrition. You'll love the results!

No success 0 people found this helpfulI thought this was a great idea; low mess, no transplant stress. I ordered 4 bio domes and refill sponges. I have read and reread the instructions thinking I might be doing something wrong. I’ve tried them under grow lights and in indirect sunlight. I’ve had them on and off heat mats. I have had no success. Not one seed has germinated in these. I even tested my seeds in other medium to ensure the seed was viable. I’m really disappointed.

Sponges 1 people found this helpfulI really like the fact that they are not messy like when you use soil. There were a few in the pack that were damaged and unusable but there was extra in the bag so it evened out. I planted my seeds 6 days ago and they have already sprouted. It is definitely less messy to deal with and I would recommend them to everyone serious about their gardening as it makes things so much easier with less mess.

Seed Starting 0 people found this helpfulI stumbled upon Park Seed and their seed starting system about ten years ago when just beginning to grow plants and out of everything I tried I really like this system. I can grow usually four seedlings in each sponge. When big enough I pot them by tearing the sponge into four pieces or into the amount of seedlings I have and pot them till they mature enough and the weather is good enough to plant outside. I love this system and these sponges are great.

Economical planting 0 people found this helpfulThe refills are reasonably priced. If you plan ahead you can buy them when demand is low - they store well and don't take up much room (unlike bags of seed starting mix). The downside is these planting blocks seem to make the seedlings a bit more susceptible to transplant shock. The trick seems to be to start them in the blocks then transplant to a larger pot with potting soil later. Using these blocks reduces your risk of waste when seed starting and the effort to tease apart seedlings in bigger pots. These appear to be made of peat, which is a non-renewable resource, so if you are very "green" they may not appeal to you.
