Raising clones
Reviewed in the United States on June 23, 2023 by tom donnells

  • Okay for the money
First time using rock wool for cannabis clones. Thought I would give it a try for comparison. You need to cut to size, or trim edges after cutting a cube out of block. Then soak for 10 seconds in 5.5 ph water with a nutrient like Clone X. (There directions). I also used a cloning gel on clone stems. Seem to hold moisture well, but wanted to fall apart if not handled or cut to proper size for plug tray. Today is day 8 and decent root growth forming. I’ve just kept in dome, under minimal lighting, misting, and humid. Haven’t decided if I will switch to it permanently yet. Definitely takes longer to prepare than a traditional grow cube and more expensive. Definitely would be great for circulating system. If using like me, clean bottom tray daily. ... show more

  • The fact that I'm putting my plants in something that is bad for the environment.
So I bought the rock wool in hopes of cloning a few of my plants to go along with the seeds I'm getting ready to start. Amazon has this item rated fairly well so going off the item description this seemed like the perfect buy. So along with the rock wool I purchased a cloning gel to help root development. The night it arrived I put them both to use. I took a clone from two separate plants and used my cloning gel and then inserted them directly into the rock wool. After the first day or two one plant just completed died and the other one is swinging in that direction as well. So I was curious as to why this happened and I did my own research. Come to find out rock wool is not biodegradable and is bad for the environment. So now, I don't know about everyone else but for me when I think about plants and how they grow when they are in there environment rock wool doesn't fit in any of them. So now I am taking a piece of my plant or my seeds and trying to raise them up in a piece of trash basically hoping they will grow big and strong doesn't sit well with me. Not to mention they fall apart when you try and use them. I spoke with another grower who says you should rinse them before you use them. To help with those little pieces of fiber glass that could be inhaled or stuck in your skin. So for me the rock wool is a piece of trash they are selling to people because they don't know what else to do with it them self. I'm extremely glad I didn't start my seeds in them because I'm still waiting to get a few more things for them or I would be so mad. I would not recommend this product to anyone. ... show more

  • Use for Gardyn ycubes and in 2" plastic net cups
You can see it is a little short in the taller 2" net cups but would fit in the gardyn ycube nicely as you can see in other reviews.. I haven't started the seeds in just yet but will see how it goes! If you don't have a good priced hydroponics store around you then these are good for the price.

  • Chewy but works
I used these in my tower garden. I had success-you might too.

  • Seeds sprout well
We have had no issue with germination, and I eliminated shocking the seedlings when I transferred them to soil. There are a few methods for starting seeds, and it’s my belief that this method is the best
