How to transplant rock wool block
Once the you see about 0.5-1″ of root growth below the plug, it is time to transplant. They can go straight into the hole, as they do not have any wrapping on them. Your best bet is to transplant the starter plug into a 3″ or 4″ .
WHY? It is much easier to control the moisture level in a 3″-4″ than a larger block. Just wait until the block feels really light before you water. Smaller blocks like these will keep an even moisture level in the entire block. Rule of thumb: water 15 minutes before the block goes dry.
If you transplant into bigger blocks: It is essential to keep the upper part of the block moist by misting or watering sparingly.
