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.

Very nice shirts but unusually long sleeves
Size: Large, Color: Light Green
PJ PAUL JONES Mens Dress Shirts Wrinkle Free Stretch Button Down Shirt. I bought white, coffee, grey, autumn green and apricot. Colors are true to the ads. I'm 6' , 170 lbs. I bought these in Large. They fit very well in shoulders, chest, and my big belly. As many reviews have stated, the sleeves are unusually long - coming down past my palms to my fingers. I would give them a 4 rating for that but I bought them with the intention of making them short sleeve. The white shirt is just too nice to change so I'll reserve that for weddings and funerals. The apricot is very nice but I just wouldn't wear that color as a casual shirt but it does go with my brown blaser so I'll keep it for rare occasions. I washed them in warm and put them thru warm dryer and didn't notice any shrinkage which I wouldn't expect with polyester. Very good shirts at very good price.

A Solid Buy
Size: XX-Large, Color: Black
Purchased this shirt to wear to a concert. I love the material because it's stretchy and flexible unlike the traditional cotton. It's mainly wrinkle free but I ran a warm iron to get out the creases from being folded. I wore this with gray pants and it made my outfit feel put together. The sleeves are very easy to roll up and won't come undone. A very nice shirt to add to your clothing collection.

Good looking shirt that runs a bit big in sizing.
Size: X-Large, Color: Green Gray
Nice looking shirt for dress up or casual wearing. Feels like silk, pretty wrinkle free. Lots of colors to chose from at a good price. Runs a bit big in size. I found the sleeves very long for me. But I like the casual look, feel and coolness in the heat of summer for a long sleeve shirt.
