Lightweight, injection molded, black plastic pot filled with Grodan® Grow Cubes also known as Rockwool, an inert, lightweight and sterile growing medium. Well known in horticulture for its excellent water retention capabilities and efficient drainage, Rockwool is also a pathogen and pest resistant growing medium. To prepare the growing medium, first poke a few holes into the plastic wrap covering the Grodan® Grow Cubes and through the drain holes in the bottom of the pot, then follow these steps:

Prepare Water: Fill a small bucket or tall container with enough RO, distilled, or deionized water to submerge the pot. *Ideally, the water should be adjusted to pH 5.5 with either 100% pure lemon juice or other organic pH adjuster (pH Down). Pure water is pH neutral (7.0), so add pH adjuster one drop at a time, checking water with a pH tester until desired pH is attained. *If this step proves too cumbersome, soaking and rinsing the cubes several times in pure distilled water will suffice.

Submerge Pot: Next, place entire pot into the water solution, submerging pot completely. You’ll know when the growing medium is fully saturated when the pot no longer floats. Rotate the pot around to remove all bubbles until fully saturated.

Drain Excess Water: Maintaining that the cubes are fully saturated, remove from bucket/container, letting the excess water drain from the pot’s drainage holes.

Prepare Pot: Remove the plastic wrap/tape covering the pot. Displace enough media from the pot to make room for the plant/plug/root ball and you are cleared for transplant!

Optional Check Wet Weight: Note the wet weight of the planted pot of cubes when fully saturated, and let this be your guide for future watering cycles. Even better, if you have a small kitchen scale, weigh the plant in the pot with the cubes fully saturated.

Grower’s Notes: By allowing the Grodan® Grow Cubes to drain freely, over-watering becomes more difficult. The amount of water required between watering cycles is going to depend on the size of your plant, and your own growing conditions: light, temperature, and, especially, humidity, which drives plant transpiration and water uptake. So remember, your irrigation program will depend on your environment and your plant’s needs. Check out this short video for visual reference.

The tray method of watering is just one means of irrigation; overhead watering is another. Just maintain that trays drain or dry completely between watering so that the media maintains a balance of air and moisture. In our experience working with this media, Rockwool/Grodan® Grow Cubes have a similar capillary coefficient to long-fibered Sphagnum moss, that is, the cubes have similar wicking and water retention properties.

Rockwool/Grodan® Grow Cubes is an excellent growing media for Cephalotus and other carnivorous plants. Cephalotus growing in Grodan® Grow Cubes won't get water stressed until the Rockwool is almost completely dry. When in doubt, you can test one of the cubes from just below the surface and squeeze it. Here’s another short video demonstrating this technique. Be aware that this moisture gradient increases towards the bottom of the pot; cubes down below will always be wetter than those up top. And lastly, it’s a good practice to flush the media with pure water (or rainwater) 4X/year to help remove any mineral or organic build-up in the media.

Absolute game changer for chronically dry feet/cracked heels
Size: S (up to size 7)-Beige
I had recently bought a pair of silicone heel/ankle wraps to fill out my boot a little since I noticed my heels were lifting when I was skating. I tested them out around the house and noticed they left my heels softer while the rest of my sockless feet got quite dry. So I got these full foot silicone socks to see the effect of having my whole foot covered. I slather the entirety of my feet with Dr. Scholl's Severe Cracked Heel Restoring Balm (love how convenient it is to apply it to my feet with the solid stick form) and then slip them into these silicone socks. After just a couple hours, when I pull out my feet they're (a teeny bit sweaty at first), but then overall soft and smooth and have absorbed the balm fully leaving barely any residue in the silicone sock. I find these silicone socks generally comfortable; I wear them in the evenings while relaxing on the couch, take them off after a couple hours and let my feet breathe a bit, and then reapply my balm and socks and wear them to bed. If I wake up in the middle of the night, which I almost always do (not because of the socks), I'll take the socks off and allow my feet to breathe again. I wear a woman's size 6 shoe and the small size is pretty comfortable. However, I made the mistake of wearing them while being on my feet for a couple hours straight during household chores -- they must've somehow cut off my circulation a bit with the standing, so I wouldn't recommend wearing these silicone socks while being active. And since they're not exactly my foot size, they slide around sometimes and will start to feel tight at my big toe. But if that happens, I just tug on the toe area of the sock to give my big toe more wiggle room and problem solved. Prior to wearing these socks, I was soaking and doing heavy duty exfoliation of my feet every week. These socks seem like they'll work to help me extend the time between soakings and exfoliations. The 5 pack is a great value. So far none have torn, so they seem rather durable. Not sure what I could even do to tear a hole in these.

EXCELLENT FEET MOISTURE PROTECTION
Size: S (up to size 7)-Beige, Size: S (up to size 7)-Beige
Why did you pick this product vs others?: I have burns on my feet and needed something that I could put burn creme on and still walk around in with. I tried other silicone footsie but they would teae really easily. So far these are doing really well for this purpose. They are holding their shape too. The only caution I have is the same with all silicone footsies: They can be slippery on wet floors, so also wear with socks over them. The biggest issues is when they say a size they mean it. The silicone used in these have little give in them, so they won't stretch out and loose their shape. That can be a good thing, or not so good, depending on how well they fit your feet and what your intent is with wearing these. The other issue is if they fit snug around those toes, that tends to be where the first tear in the material will happen. Because of how these are made, the tear is actually more like cracking in the material and once it occurs you won't be able to get much use out of the sock after that. If you are planning to wear them around the house or for long term use, I suggest going up a size or look for the toeless options.
