TL : DR Working on a large lollipop grow space
Light needs = 500w per 16 sq ft or 1000w per 16 sq ft?
Lighting solutions? LEC, LED, HYBRID (LED + HPS/HID)?
I found my way to the forums here through the excellent growlog from Jameson and Mr Blakk on youtube.
With recreational weed coming to Oregon I am doing some serious research and planning into large scale operations. I have a space in mind, an 1100 sq ft room with 12 ft ceilings and an intended maximum space of 794 sq/ft for flowering and veg. I have a separate 45'x17' space for cloning - mothers - nute prep - plumbing, etc.
So here is my issue, we have a budget that can support LED or LEC and I am at loss after a few weeks of research with companies on exactly what my lighting needs are. I have put out quotes and am not having much luck with responses, maybe it is just a backlog from the holidays but I am thirsty for knowledge here.
The convention seems to be 500-1000w per 16 sq feet (4’x4’ foot print). with many LED companies comparing output of their lights to 500w HPS. What do you suggest?
With this in mind I have come up with some calculations. Namely that each approximately 20’x20’ space would need 25 lights (50 total), a lot of heat and additional HVAC here if we chose traditional HPS or HID.
So the front runners are:
Sun system complete lec 630 and 315 Here
My current calculations consider the lec 630 to cover a 4’x8’ foot print and the lec 315 to cover 4’x4’
which would mean 24 630’s and 2 315s (here is what that looks like approximately) about 25k in lec
Seems low density in terms of light placement. Though I am pretty certain this would work out to an equivalent of a 500w hps on every 4'x4' segement. the overlap from the outlined grow area on the included sheets is about 1 ft. on the perimeter. The intent is provide for good canopy penetration with this perimeter.
If the calculations are correct on the w/sqft then an equivalent led solution is ~37k from supergrowled using SK450's Here (thoughts?)
Here are the two layouts we are considering:
Posted this over on NWGT as well, will try and update information on this as i get quotes from manufacturers back.

I'd go with mh and hps. For the flowering room I would put three rows of five 1000 watt hps evenly spaced and between the rows of plants I would suspend vertically every 15 feet or so 600 watt hps. That way all you plants are covered in light. A little pricey to start out with but it will pay for its self with the first harvest
