wow good job tying her down. looks like she'll be a producer. subscribed
My 250w has a glass shield and I keep it around 8 inches off the tops just using computer fans.. temps between 78-80. A little higher than normal but they do alright250w with a glass hood you can get up to 18-12 inches away depending on how much light your plants can handle.
and i wouldnt worry about yielding more if you've only flowered with cfls before. before i moved to cali i would pull a qp minimum (depending on the strain) from 6 sqaure feet with a 250w, granted i had a sog and not 1 good size plant
I started real close, like 4" from the glass shield.I have a 100cfm exhaust fan and ducting but in a closet without good venting, it got hotter in the room with the exhaust air heating the ducting, no cooler under the light really.My 250w has a glass shield and I keep it around 8 inches off the tops just using computer fans.. temps between 78-80.

I now have a fan hitting the light from below, and one across the top of light, and plant canopy. The cheap 4 or 5" metal fans. Also a 16" fan blowing across the grow area.
With the door open room temps stay below 80 under the canopy it's pushing
86.
I have a plan for venting the light after this grow. Hope to get temps a bit lower.
I'll also start higher with the light and work it lower as i flower.
I'll post some pics of my grow space when my lights come on this afternoon.more pics? I'll be using a 220w hps (most likely) so just trying to see what abouts I'll be working with given you're setup.
You're right. Had problems with ph.Your leaves are getting yellowish, Even though thats practically normal and most likely won't harm it, NPK?
3'x3'x5' could go higher if needed but i use less than 3 feet of vertical space.what size is your grow space?
