Re-Pot or Leave?

Re-Pot or Leave?

I started some pumpkin plants from seed this year inside in those little plant pellet things. Two of the plants are growing bigger while the 3rd is just starting to sprout. Should I re-plant these into their own pots or leave them as is until I can plant outside? I'm in Zone 3A (Northwestern Ontario, Canada) and typical rule of thumb is no planting actual plants until the first week of June, seeds can be planted May long weekend. What should I be doing to water the plants inside the pellets? There were no instructions in the kit I bought!
