I have used Rockwool starter cubes for years, both for seeds and cuttings in my hydroponics systems.
This is the first time using this generic brand but are the same as others I have purchased from local stores, except they are cheaper here.
As for instructions, do you really need them, If you don't know about rockwool then you should read up on it on the internet to make sure it fits your needs and purpose for the type of plants you plan to grow, there is almost as many variations of how to use this product as there are plants.

Rockwool is a trade name not a brand.

Breathing the dust of rockwool can be hazardous to your health

Also to answer another reviewers question, Rockwool is a fibrous material made from molten rock. It is NOT biodegradable but mishandled will crumble to a fine dust

Pros:
Cheap cost same quality as most name brands
Hole in middle to place seed or cutting.
Convenient cut or tear squares.

Cons:
None

Mine shipped without a bag, label or instructions but that doesn't really bug me too much. As other reviewers have noted, this is "economy" rockwool - it comes in a big sheet as pictured and you break the individual plugs off. This means they're a little rougher around the edges and a bit more powdery than the somewhat costlier rockwool products. If you're just looking for a good, cost effective rockwool then this will suffice.

Just ordered a second set. These work just fine and as far as I can tell, are the least expensive.

I have tried the peat plugs, sponges, larger rock cubes, loose seeding soil.. and this product is just as good, better than some of the above and very easy.

Very economical way to buy this product. Mine had instructions - just rinse with suggested ph adjuster and use.

I am just amazed at how this little cubes work so well. It does not matter whether I am using for starting seed or my cuttings from mother. I have never lost one and the rooting time is very very short. Try these you'll be glad you did.

this was shipped fast but was not in plastic why??? this is supposed to be sterile and i cant be sure of brand name now .maybe it was a knockoff ... i cant tell ....for cloning it is important to be sterile and it cant be when unwrapped ..waste of money should be blatant in description that it is naked in cardboard shipping box.

I bought this because I really want to germinate Bhut jolokia...I failed many times. More then 10x...so, I read in one forum he use this rockwoll. And he's right. My bhut Jolokia sprouting now....thanks

Grodan Rock Wool Starter Plugs are good sterile option for anyone using cuttings. Of all the methods for cloning this seems to be the simplest to use.
I thought the product was very useful for the serious and causal gardener.

becuse they wernt in a bag ,you should place in boiling water for 15 min to kill anything might inhibit ur growth

mehh this product is just ok..the shipper was great to ship very quickly price was a little too high and as always shipping is over priced..product falls apart easy but does work..just don't saturate in water..
