Description

The manufacturer has many years of experience developing Rockwool products in the Netherlands and is preferred by some of the largest industrial propagators in the world. The quality of their newest Rockwool cubes, plugs, and starter sheets is by far the best on the market with superb air to water ratio and a fiber structure that holds water longer and has less resistance for the roots to grow in, resulting in stronger roots. Rockwool also encourages faster initial rooting and its firmness is guaranteed. Blocks measure 1.5” x 1.5” x 1.5”

Size: 30 Per Pack
dont use on seedlings (marijuana) unless you cut one from the middle-outwards so the taproot has somewhere easy to go (downwards following the slice) otherwise the roots struggle to grow through it. Moved my seedlings into small party cups of soil and they all took off much quicker (was even nutewatering the rockwool low dose). 1 of my seedlings was stuck in the rockwool and rotting since it was having such a hard time growing down (didnt cut down middle), it wasnt until i moved it to soil that it took off. I'm sure these will work better for clones and such but i wont know until i try it in about a month or 2. ... show more
