Review: Terrific seed starting plugs - I purchased these plugs to use with our LettuceGrow hydroponic tower. I’ve had great fun choosing and starting my own seeds. Enter Root Riot plugs … Typically we harvest 2-4 plants for our weekly salads, so we usually start about 12 seeds every 2-3 weeks. These plugs arrive moist and ready to use; but since we stagger their use over many weeks, we lay the new plugs out on a cookie rack and let them dry out completely before storing. When we are ready to start seeds, we just rehydrate the needed number of plugs for a few minutes. We have had no issues with molding or algae growth when working with the dehydrated plugs and they perform just as well as they do when they are new. (We did have issues with both black mold and green algae when we tried some less expensive foam plugs.) The first pic shows the varying levels of growth and variety of seeds that we’ve got started now. (Cucumbers, peppers, lettuce and some flowers.) The missing plug was transferred to the tower last weekend! Cucs, peppers & flowers are destined for outside planting - and that front right tray (with all the baby lettuce sprouts) was just planted yesterday! The second pic of the tower (with varying levels of plant maturity) shows how the plants are growing. The Root Riot plugs are perfectly sized for the 2” baskets AND they fully support the mature greens in our Farmstand. The third pic shows how developed the roots are at harvest along with a typical salad. It’s cool knowing that our greens have not languished in a grocery store, have only been handled by us and have absolutely no pesticides. Added bonus, no dirt or sand to wash off when preparing the week’s salad. Greens don’t get more fresh! Bottom line: we wouldn’t be this successful if we were using inferior plugs. My only wish is that they came dehydrated so that I wouldn’t need to dry them upon arrival … but even so, this is an awesome product and is perfectly suited to our seed-starting needs.
Review: Great choice - Work fine. Less expensive than those sold by my hydrogarden company.

### ⭐⭐⭐⭐⭐ Great choice
*by B***Y on February 19, 2025*

Work fine. Less expensive than those sold by my hydrogarden company.

### ⭐⭐⭐⭐⭐ Easiest way to root your cuttings.
*by K***K on November 25, 2025*

10 out of 10. I use these plugs in my home garden and at a commercial farm with 99%+ success rate. Using a heat mat under your trays to regulate temperature will increased speed of rooting. These plugs are great for transplanting into any growing medium. CloneX Cloning Gel recommended but cuttings will still root without it. Recommended using CloneX Clone Solution fertilizer to promote health growth and prevent leaf yellowing.
