Hi Joris,
apologies for the slow response – I’ve only just seen your post. Yes, you can rehydrate your bags by submerging in water overnight. Water will soak up into the substrate and mycelium and help to give bigger subsequent crops than if you don’t reydrate.
The easiest way is just to fill a large clean container with water, put the bags in and then you will probably need to weigh them down to keep them submerged.
Hope this helps.
best wishes, Adam
