Burpee Seed Starting, Super Growing Pellets 72 ct. Seeds

The super growing refill pellets don't expand very well. About 2/3 of my 72 Pellets didn't expand, and I had to break them apart in my growing tray, to the water could drain out of the cubicle. It took a lot of time and caused me to damage the thin plastic seeding starter tray. Use something else for soil medium, and save yourself lots of time and eirk

Mixed results - Pros: I loved the idea of the convenience of these vs having a bag of starting soil and the fact they were premeasured was a plus. Cons: directions didn't say that the pellets had to be placed in flat side down, the ones on their side either wouldn't expand or expanded and tore the bottom of my tray inserts (that are on their 3rd season) and a couple that didn't fall all the way to the bottom expanded over the top of the rim and the top part of the pellet fell on the floor. In the end, since I had to force some of the pellets out to reset them flat, I ended up making as much of a mess as the soil would have and ended up wasting a portion of the expanded pellets. I will try them again and given this experience it should go better - hopefully!

I bought these thinking they were like the netted peat pellets I've used for years. When they arrived I saw that they were much smaller, but boy, do they deliver! I dropped one per cell in a tray of peat cells, added a little water, and poof! the pellets turned into little towers of growing mixture (which you then tamp down into your peat cells and add a little more water). I planted a mix of seeds in them (annuals, tomatoes) and have had excellent germination. I like how compact they are, too. Storing extras takes up little room. Sold.

I bought a box of these and only 10 out of the 72 expanded and the rest just sat there and got as hard as rocks. Save your money and buy soil instead.
