Ok i have 600w conversion system that i can also use a 1000watt bulb( have bulb).And i have a 400 watt system that i also want to use.should i use the 1000 and 400 or 600 and 400.how mant plant could i grow(i have plenty of room)
I'd use the 400 or 600 to veg then turn on the 400 and 1000 to flower... More light is always better IMO! Do as many as you can fit comfortably?! The amount you can grow also depends on the system you use and the strains you grow not just the lights..
