They can go straight into the big rockwool 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.
