Carinia is right that peat is too acidic for cannabis, and the nets are too tough.
Luckly the peat pucks are pH adjusted with lime- the amount of time your little plant spends in there is short if you do it correctly, and as long as you make the transplant into a much better soil, you shouldn't see any problems.
If you use pucks or juffypots, when you transplant, shred the pot or net up a little bit to let the roots grow more freely before planting.
