Root Riot Plant Starter Cubes Made from Sphagnum Peat Moss. Ideal for Cuttings and Seeds, Designed to Support Robust Root Development - 100 Cubes

Root Riot Plant Starter Cubes are a fantastic choice for anyone serious about successful germination and propagation. Whether you’re starting seeds, rooting cuttings, or working with delicate plant varieties, these cubes make the entire process smoother, cleaner, and far more reliable. The first thing you notice is the texture—soft, spongy, and perfectly moist right out of the bag. They hold the ideal level of moisture without becoming soggy, which is crucial for young roots. Seeds germinate quickly, and cuttings take root with impressive consistency. Even beginners will see great results with minimal effort. Each cube has a pre-made hole, so planting seeds or inserting cuttings takes seconds. They also retain their structure extremely well; they don’t crumble, break down too fast, or compact like some other starter mediums. This gives roots the space they need to grow strong and healthy. Another huge plus is how clean and mess-free they are. No dealing with loose soil, dust, or mixing growing media—just grab a cube, plant, and go. They’re compatible with humidity domes, trays, and hydroponic setups, making them incredibly versatile for gardeners of all styles. With 100 cubes in the bag, the value is excellent. You get plenty to start multiple batches of plants or keep stocked for ongoing gardening projects. They store well, stay fresh, and are ready whenever you need them. Final Thoughts: Root Riot Plant Starter Cubes offer outstanding germination rates, easy handling, and consistent performance. They take the guesswork out of starting plants and give your seeds and cuttings the best possible start. If you want healthier roots, faster growth, and a stress-free planting experience, this 100-cube bag is a smart and reliable buy.

I’ve been using the Root Riot Bag of 100 plugs in my hydroponic NFT system, and they work perfectly. The plugs hold moisture well, provide excellent aeration, and promote strong root development. They’re easy to handle and transplant, making my planting process much smoother and more efficient. The quality is consistent across all plugs, and the 100-count bag offers great value. ✅ Pros: – Excellent moisture retention and aeration – Promotes healthy root growth – Easy to use and transplant – Consistent quality – Great value for quantity ❌ Cons: – None so far Bottom Line: If you’re running a hydroponic NFT setup, Root Riot plugs are a top choice for reliable, healthy plant starts. Highly recommend!

I live in Colorado so cannabis is legal here, so that's what I use these cubes for. Well, they are actually more conical in shape but they fit in square germination / cloning trays perfectly as well. I've bought these from the beginning of my germ / clone cycles and they work perfectly. Unlike rock-wool cubes that are irritating to the skin, you can handle these for hours and never experience an irritation to the skin. They are as soft as a wet sponge, hold plenty of water, and have tons of air space for excellent root growth. I know this sounds like hype, but I've used over 300 of these cubes, and I have had 100% germination / cloning rate. I use a heat pad under my 50 cube germ / clone tray, and put about a gram of root solution in a gallon of water and fill the tray. Then I spray the clones with a folier spray, put the 7 inch hood on the tray, and let it go. If using seeds, keep them in the dark until they sprout, or if cloning then keep a low watt grow light over the clones 24/7 until you see roots starting to come out of the cube. Then either veg your plants for a bit, or move them directly to flower mode for SOG (sea of green). All of this can be googled and you too can grow great plants, or just e-mail me and I'll help you out. Either way I clone all my mother plants for twice the numbers I need, then I pick the best growing plants to keep, and sell my excess to friends and family. I've never had a plant not seed, or clone properly, so I will continue to use this product. And don't get me wrong, even though the majority of my grows are cannabis plants, I also grow tomatoes, peppers, peas, cucumbers, basil, cilantro, parsley, lettuce, and a few other garden salad type plants in these cubes too. I run a DWC (deep water culture) type of hydroponics, typically known as RDWC and bubble ponics. It's basically a top fed DWC and I can attest to shaving off about 2 to 3 weeks of growing time from seedling to harvest. Or clone to harvest is even a bit quicker. Just keep a mother plant or two around to take cuttings from and you'll never have to buy seeds again, and you can make your own seeds if you want. Either way, a great product, highly recommended, and I will be buying these for a long time!!!

Good product, good price, good service

Easiest cubes to use both in and out of the tray. Turn em upside down and they stand up right for ziplock cloning tech. Roots in 7 days!

these cubes are easy to use and have a very high success rate. they are shipped in a bag with moisture in it and need to stay moist. if they dry up they are really never the same and I have little success using them after that point even with a full soaking. I recommend using a cloning or rooting agent on cuttings, no need if using seeds. keep the cubes in a moist environment afterwards for a couple of weeks, misting at least once a day and leaving some water in the bottom of the trays. I find that a heating mat under the whole arrangement seems to help them propagate, especially if you are in colder climates. I also have better luck running a light and keeping them indoors, it helps to avoid temp swings.

Really gives new seedlings 🌱 great roots

Perfecto para enraizar mis esquejes

Ottimi cubetti moto morbidi ed ariosi credo che per talee e germinazione siano un ottima alternativa hanno un ph stabile facili da utilizzare

Cela fait la seconde fois que que j’en commande. Ces cubes sont très pratiques, déjà humidifiés, ils sont prêts à être utilisé pour vos boutures ou graines à germer

Super Anzuchtwürfel, seither funktioniert es super mit dem Bewurzeln lassen.

I turned away from box standard Rockwool plugs to use Root Riot cubes a long time ago. Success rates when cloning are now 100% with rarely any loss due to the pre-soaked/enriched cubes offering a far more welcoming root zone than that of Rockwool which involves far more preparation and monitoring than Root Riot. Although the cubes come pre-soaked I generally end up adding a little more moisture. Understandably, older shelf stock does often arrive a little dryer than cubes just leaving the factory floor so a little bit of adjustment is necessary but for beginners or people who are happy to pay a few pounds extra for an easier life then these are the plugs you need!! I observe rooting emerging from the plugs in 10-14days (when using clonex rooting hormone). I can't imagine using anything else other than Root Riot and Clonex together to produce my clones. HIGHLY RECOMMENDED to all.
