I'm setting up an indoor grow with 6 Northern Lights. I'm just wondering what the lighting schedule will be throughout. I have a 600watt HPS Bulb inside a grow tent. EDIT: Would I be able to use the HPS whilst young-lings?
Yes but keep the light further back than the normal, although your plants will grow spindly with popcorn type bubs, better to use Mh or 6500k bulb during veg peace "V"
