I start my lettuce in these for use in my home Kratky system net pots. Easy, reliable and no bad smells.

I can't argue with the low price. They are a bit rigid and require a sharp box cutter or scissors to take apart, because if you tear them, they tend to fall apart. Even cutting them with a box cutter left quite a bit of dusty residue on the table which you probably don't want to breathe in, so I also recommend cutting them outdoors. I'm going to try and pre-moisten them before cutting them again. But my seedlings really took off in the cubes, so I'm happy enough with the product.

These little things work very well for seed starting. As per the instructions, use a pair of scissors or a knife to separate them. I tried just breaking off one, and it broke it and the adjacent cubes a bit. If you stick to cutting your cubes out, it works. I have to widen the indent where you put your seed. It isn't very large, so you might need to adjust it a bit to get your bulbs in there.

PROS: I cannot think of any. CONS: (See photos) 1 inch cubes are only half the length of other brands so they are much too short for 1 inch net cups. They are soft like cotton candy and flaky like biscuits and fall apart with handling. Plus, they excessively shed glass fibers when handling. Because you have to use 2 to make the size of one normal sized 1 inch pod and they fall apart, the price is no bargain. I AM an avid hydroponic grower and have experimented with several brands of rock wool for my lettuce, greens, cucumber, beans, tomato and seed starting systems. I use Kratky, ebb and flow, deep water, and hybrid systems. Although prices may differ I have found that all the rock wool cubes I ordered were basically of similar quality, allowing me to grow enough veggies to be able to share my bounty with many friends and neighbors and even strangers who appreciate fresh produce. That was until I ordered these. Some broke apart while taking them out of the box. Some flaked into pieces as I was removing them from the pre soak. There was way too much "rock dust" falling from the product. As I have already mentioned, each pod was 1/2 the size of any other 1 inch pod I have ever used, so I had to double them up to prevent light from entering my system. I do not recommend, so will be returning them and purchasing another brand.
