I transplanted my seedlings into six inch rockwool cubes and forgot to prepare the new cubes, is it to late to still soak the cubes? The new plants have been in the cubes for a couple days already.
That's what the guy at the hydroponics store told me also. I'm going to see if this helps the plants. I have ten purple OG Kush, two GDP, and one white widow, and of all of them it seems that the WW is the most finicky and the GDP don't mind the high PH at all.
