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: 💯 % WORK - When i use the cubes i have 98% germ rate and 100% clone rate. If I use Anything else I have about a 50/50 shot. Not sure Why this is but it’s True. I Highly Recommend this Product along with Clonex when cloning. ## Features - Root Riot Cubes are ready to use right out of the bag - Root Riot Cubes are ideal for rooting cuttings and starting seeds - Root Riot cubes are comprised of pre-moistened and pH balanced sphagnum peat moss - Root Riots provide outstanding results for growers - This product is not manufactured by Scotts Miracle-Gro, for any questions please reach out to the manufacturer identified on the product package. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B007ZU5YUO | | Best Sellers Rank | #17,135 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #611 in Garden Fertilizers | | Brand Name | HYDRO DYNAMICS | | Coverage | Medium | | Customer Reviews | 4.7 4.7 out of 5 stars (2,292) | | Item Form | Cubes | | Item Type Name | Root Riot Plant Starter Cubes | | Manufacturer | Hawthorne Hydroponics, LLC | | Model Number | 714132 | | Specific Uses For Product | Root Development | | Target Species | plants | | Unit Count | 100.0 Count | ## Product Details - **Brand:** HYDRO DYNAMICS - **Item Form:** Cubes - **Manufacturer:** Hawthorne Hydroponics, LLC - **Number of Items:** 1 - **Specific Uses For Product:** Root Development ## Images ![Root Riot Plant Starter Cubes - Image 1](https://m.media-amazon.com/images/I/61Mbbe4t9UL.jpg) ## Available Options This product comes in different **Size, Style** options. ## Questions & Answers **Q: What are the dimensions of each cubes?** A: Approx 1.25"×1.25"×2" **Q: Are these good to use in coco coir?** A: Yes I use mine In Coco coir and they work great in coco Coir **Q: Can these dry out?** A: Will they dry out?
