i only have a 400 watt mh. cant find a hps that i can afford right now. was thinking about ordering a 400 watt hps ballast kit from htgsupply.com its only $70 with shipping i think.
the cheapest ive found for full sectrum bulb for a mag ballast is $80. i'll do this grow with just the mh most likely. i need a better inline fan more then a new light. i dont think the two 160cfm inlines are going to do the job once i add the active carbon to the drier vent for smell control. cheapest 6" inline i can find is on ebay for about $100 with shipping and its a 530cfm.
when i can have a real grow room with space i'll have both mh and hps durring the whole grow.
From what iv read this is the way to go. Best of both worlds. If i had space i would have 3 lights. 1 MH and 2 HPS with the MH in the middle. That would be dope
sounds good to me. dont worry my memory sucks to lol. part of it is from getting hit by a truck when i was a kid tho.That shows how good my memory is. Ah well i will be here when ya next ones about
thats what i was thinking
small hps for veg and small mh for flowering. the small ones used for side lighting hanging verticly.
Sorry im no electrician. Do you need to?
