Customer Reviews

I've been really kind of amazed at how well the seeds, all of them, have done.
Paula Scherschel
Once planted,I get excellent germination with the plugs which will wick just the right amount of moisture to the seed.
C. Van Raalte
These work great for starting seedlings before transplanting into clay grow media.

I had used rockwool, but after reading some reviews thought I'd give these a try.

They keep an even dampness better than rockwool. Rockwool can easily get drenched, but these seem to keep just the right amount of moisture.

When I first got them I was surprised how much they looked like moist chocolate brownie cake. Even the spongy feel made me think "This must be delicious". I never caved into that temptation, but to this day they still look and feel more appetizing than most brownies. I give a star for that alone.

They also fit perfectly in the "Hydrofarm CK64060 Hot House with Heat Mat," which is convenient.

I have used countless numbers of this product to make cuttings. I get well over a 95% success rate using Rapid Rooters. I have never had a disease problem or any other problem with this product other than the occasional mis-shappened cube.

This replacement package does not contain any information as to the proper use of the product, you get some with the rooters tray (the tray is neccessary and not included with this product), but even those instructions are very vague. This is what I do. Take your cutting as best suited for your plant and use a rooting compound, I use Clonex gel. Basically, you need to keep water in the tray below the cube, but enough to keep the temperature and humidity high. Every once in a while a little moisture will need to be added to the cube directly to keep the water to air ratio proper. Place the tray on a heating mat and cover with a suitable clear cover, I use the 8" tall option with vents. I also remove the cover a couple times a day to allow the air to change, this seems to help me a little with my cuttings health. Set all this under a florescent light and your good to go.

I place my cuttings (cubes) in a hydroponic system and I have to keep an eye on the cubes during the plants growth to make sure that the wicking action of the cube does not create a toxic buildup of nutrients at the base of the plants. This is similar to what you have to watch for when growing in soil or other substrate medium, such as rockwool. Flushing the plants from the top down is the solution to this. I find that in older plants, such as mothers, the plant soon overgrows the cube and this is no longer a concern.

Rapid Rooters are my favorite rooting cubes and I expect to be using them for years to come.

I noticed most of the reviews here are about seed starting. They do work well for that, but I wanted to also say that they work well for hydroponics. I use these for growing hydroponic lettuce in my basement. I place these pods in a 72 cell seed starting tray under a grow light. Each plug has a dimple around 1/4" deep to deposit the seed. The only issue I have with these pods is that the dimple can become misshapen, and therefore difficult to insert the seeds. I don't typically use all 72 cells, but I try to maintain the water in the bottom at a level that will keep the plugs moist (but is well below the seed) regardless of how many cells are filled. Once planted,I get excellent germination with the plugs which will wick just the right amount of moisture to the seed. Once the plants are well established, I select the heartiest to put in net cups. Holding the plug in place, I pour in expanded clay pellets to fill the space in the net cups. The cups go into a Styrofoam holder that sits in a planter trough filled with water and nutrients. The plugs are just the right density to allow water in, and allow the roots out. This is a simplified summary of my system, but the Rapid Rooter Plugs are at the heart of it and work well.

Having trouble propagating new plants in rock wool and don't know where to turn? THIS is the product for you. These plugs come soaked in special nutrient solution that promotes vigorous yet even root growth. You will finally have roots shooting out everywhere like in all the pictures of rooting medium you see online. I would suggest that you only slightly moisten the plugs upon use and be sure to squeeze any excess hydration out of them. In order to promote root growth you cannot have a fully saturated medium - that way there is a balanced mixture of moisture and available oxygen which will NOT be achieved with fully saturated plugs. Try to keep them the color they appear in the product photo, as a darker more saturated plug will leave you with rotten shoots and no roots. I 100% recommend this product for all your rooting needs, an especially from Amazon.com as there is not a better price out there!!!

These things are great. Really work at sprouting plants effectively and quickly. You can that transfer your plant to any growing system you want. I use to use them for an indoor hydroponic basil garden, I've cut them down to fit in an aerogrow as well, and as of late I'm just simply transplanting them into the ground outside. The plants always take quickly to the new environment. I'm hooked.

I've tried a couple brands and i think the Rapid Rooters are the most consistent and are softer/foamier than the rest. They work as good as the other brands so i dont think any particular brand performs any better. Using these rooting plugs i feel a tad bit more comfortable my favorite tomato plant cuttings will root because of the consistency of the plug itself. If you tear them open, they are like moist cake, where other brands i've tried are like a semi-dry brownie..
