Pure Coconut Coir Netted Seed Starting Pellets - 42mm - Pack of 50 - Sustainable, Renewable, Unamended - Superior to Peat Plugs - High Water Holding - Minimize Root Loss & Transplant Shock

So I had to test this out well before I wrote my review and I'm glad I did. At first, everything seemed awesome, seed sprouted and grew well. A bit of a stretch but that's because I had my lights too far away. No, the problem is when my plant turned out to be a male, I uprooted it and looked at the root system before throwing it away. The roots literally grew up out of the hole in the bag and then down from there. Almost NO ROOTS PENETRATED the bag! And the bag did NOT decompose one bit in the 6 weeks it was under ground. And if you have to cut the bag off when transplanting, well you might as well just grow in a plastic pot because cutting the bag off will cause transplant shock (I tried it also). So I have most of the product left and honestly, I'm just going to open all the bags and just use the coir by itself. What a waste.

I use them in a fresh water fish tank to plant cuttings. They work great, and do not harm the fish or foul the water like peat would. Plants recognize them as soil and root into them. I allow them to absorb water and inflate, then remove about 1/5 of the coir and discard. Put a few rocks in the bottom to make them sink, and add a fertilizer tab, the plant, and use a small rubber band to hold the top together. Bury in the bottom and forget about it. No problems!

These little pods make it really easy (and fun) to start your seeds. Once they grow out a bit, you can simply plant them in some rich soil and continue to watch them flourish. (Yes! The roots will grow through the container!) Highly recommended. Fun for all ages!

These are very compact and space efficient but they’re so much more expensive than a bag of potting soil. I think it will cost less, in one season, to just buy a second greenhouse.

I was really happy to find peat pellets that were made with coconut coir rather than peat, since peat is an endangered resource. But it turned out to be incredibly hard to grow anything in these. They tended to dry out really quickly, and the plastic netting never did biodegrade, even though it was supposed to. I would not use these again.
