Stewart warner has got it! No harm in getting a head start. This does draw one question in my mind. Just a random thought. If the photo-periods are out of sync between the indoor grow and the actual time of transfer to outdoor environment to what the sun is naturally doing, would this shock or stress the plant in any way for any unnecessary amount of time? Say your indoor and you are vegging for 20-24 hours and then you transfer outside to a photo-period of less amount of light. Something to ponder...
