Grodan Delta 8 Block 4 by 4 by 3 Inch with Hole, Case of 180 Blocks

Easy to work with, they hold together very wellThey DO NOT have holes in them for clone plugs etc so you can shape the opening for whatever type of starter you used. Very handy and these big ones are much better for browing big plants than the 6x6x6 Hugo's, over 2x the volume

good

One block was damaged. The hole has been opened and some of the wool has been pushed down. This reduces the area for roots to take hold, but not by much...

There's a reason they call this cube the "Big Mama". Plants get huge!! I grew Dwarf Yellow Cherry Tomatoes indoors last winter. They should have topped out at 2 feet tall. Instead they grew almost 5 feet high. If bigger is better, the Big Mama is Best.

Use these to grow monsters! Fits perfectly in a gen hydro water farm bubble bucket. Plants love em. I use in a recirculating top drip dwc. I just let my 1.5" Cube sit on top and the roots do the rest. Was having root rot issues when using clay pebbles and other medium, not with these!

Nothing beats the brand Gordan.

Great wool no missing pieces and sturdy as it should be other companies falls apart when wet. This is where I will order from next time just prefer 4x4x4 next time but what I got works this time for me!

I have not used this exact one yet, but I used one before for a cutting of my Tomato. I should have probably used a bigger cube, but this one grew it into a large vine and did better than many of my Coco coir ones.

I got individual blocks from Amazon for less than the full-case price at a local hydroponics store.To give some context for the size: I use 2 and 4 gallon square pails from ULINE for my hydroponic system. I used to use 6" cubes. They would be 2 inches from the top of the 2 gallon container, which made it tricky to fully cover the cube and prevent algae growth, plus it would rattle around side to side and tip over when the plant would get to big sometimes killing the root system and plant.With the 8" cubes you have to force them down into the 8" x 8" x 8" 2 gallon pail, and once they're in they are flush with the top and have no play side to side. I haven't finished the grow yet, but these cubes seem like they will substantially increase my yield.

It huge. I slice into 4 layers and use for cuttings. works great
