First time lol, Once I've got my seeds sprouting, can I let them grow for a bit indoors then move them outdoors? In April/May? I've found like the perfect place
In general yes. But I think you've sprouted too early, you would be planning to veg these indoors for 2-3 months then putting them outside to veg for another 2-3 months. I haven't grown outdoors for a long time and didn't know then what I know now, so I'm not sure if 5-6 months of veg would be too much. Depends somewhat on your latitude and the strain you have. That's my 2¢, we need to hear from some more experienced outdoor growers...
they probly get really big depending on the strain but yeah you can probly get a good yeild with that long of a veg stage.if it were me i would top the shit out of them so it would bush out
