Alright so i have a 120W LED lamp and was wondering about the veg and bloom cycles. Typically i know you are supposed to use a MH for vegging and HPS for blooming. Yet what do i do with an LED. Once i have the desired size and want to bloom do I just change nutrient solution to bloom and sit back and watch the show?
They sell Veg/Bloom/ and full cycle LEDs. As for flowering if you have a Veg LED you can still flower with it but it wont be the light required but you still can. You can start to finish with any light HPS or MH. Just one happens to be more conductive to a certain stage but the plant will still develop.
