Kinda spendy, but quality rock wool

Kinda spendy for rock wool. But they did throw in a measuring card so that’s kinda cool. Rock wool is definitely a go to for planters.

Hydroponic must have!

Just starting in the world of hydroponic gardening, and I have watched videoes with people using these, and they were telling the truth when they say thet are amazing!They help with the seedlings and hold moisture really well. Transplanting has been so easy with these!! Will be buying more!

Hydro cubes for the win

Normally I use alternatives to rock wool but since I’m experimenting with hydro peppers this year I figured I’d give these a try.Benefits: hold moisture, roots have no issue growing through these, they fit nicely in my 3inch net pots and they do not fall apart like other brands.Would recommend

It works. However, algae also loves this item

Perfect for seedlings. No mess, no dirt

Used these to start my kale lettuce seeds. They come with a tiny hole in the center to simply drop the seeds in, i used a toothpick to press them down snugly. The pods fit perfectly into the seedling starter tray. They are firm, but have enough flex for a nice snug fit. Planted 2 seeds in each pod, wet them down with my aquarium fish tank water and set under an inexpensive grow light. Pics are the results 1 week later. Rockwool is the best. No dirt, no mess, and almost instant seedlings. Little pricey compared to soil but worth every penny IMO.
