I have heard of many different ways to presoak your rockwool...from what I hear is if using grodan rockwool you only need to presoak for 30 minutes unlike 24hrs for other brands......is this true??.....PH of 4.5......5.0.....5.5..??????....with nutes or without????
I am using the 1.5" cubes to make some clones...plan on using rooting hormone powder.....and I have propogation trays...1 with holes 2 without....and a humidity dome.....with a hydrofarm heat mat.
any help on properly preparing grodan rockwool for clones would be great.
