Hi, because the day duration is too short now. I want to plant about 9 trees (photoperiod) this month and using a lamp for the veggie phase and move them outside during the flowering phase. Or may be, i let them outside all the time but the during the veggie phase, i add the lamp on evening. For example, i expose them to the light from 18 PM to midnight, so they will get about 18 hours of natural and artificial light. I try to find a cheap solution. The lamp for veggie and blooming is very expensive and i don't want to pay a big electricity bill. Is it a good idea do you think ? Cheers
