gooday to all,
i have a question concerning force flowering: when going to the 12/12 regimen, does it matter which light type i use?
i have an Apollo 600 light system which came with an HPS and an MH bulb. would it matter which bulb i used to force? i have been using the HPS bulb during the vegetative stage and wondered if i should use the MH bulb to aid in flowering?
thank you in advance for your help.
