Grounded, covered outdoor outlets are common around here..
That may be the case but a light fixture would probably not be water proof. You could be in for a shock.....literally.

you would need 2000 Lux if actively growing
Yep I have 13,000 on my shade tolerant terrarium.Is that accurate? I keep my citrus through the winter under 4 t4 + 2 t4 lights which is about 12,000 lux. That's barely enough to keep them going and doesn't penetrate the canopy well. Full sun can be more than 100,000 lux. I thought pines needed a LOT of light.
But I done lotsa bad stuff to the tree itself.
Piecemeal good intentions at wrong times.
Gonna use sock puppets.Looking forward to the youtube video...
Only if they're electrified...Gonna use sock puppets.
Still lookin forward to it?
I think the idea is to test, as I suggested on an expendable.
Equally important to the tree is the dark cycle. So you end up extending the period of light, so shall you the period of dark. Sounds like more trouble than it's worth.Sure, would be interesting to see.
A good source of data would be research focused on commercial greenhouse operations. For example, this link has valuable information. Commercial and research operations usually measure daily light integral (DLI) which is the total light over a period of time. 1000 lux for 16 hours is ~= 1.06 DLI for comparison. Full sun for the purpose of commercial growing is generally between 18 and 60 DLI.
I would suggest that a powerful 400W HID bulb be used, and consider extending the day by providing supplemental light in the morning/evening. This could potentially get you to 50 DLI over a 1m^2 area -- even off-season.
Amen....
UV is pouring through those clouds.
There is a light that almost produces the 'full spectrum' that the sun does. In different intensities through the spectra albeit. It's called plasma, serious. It's rather inefficient though, as are most artificial light source. But if you got the dough you can work around it; but simply putting a pine under a grow light is not gonna cut it. You would have to place the pine so close to the light source to obtain the UVA and UVB photon fluxes that the sun produces that the infrared emissions would cook the needles. Could you get away with placing the pine further from the light? absolutely, but it would be very difficult to get the same results as outdoor growing with proper placement and care. The infrared emissions from artificial light sources drastically increase the relative humidity in a 'grow room' environment. There is a huge discussion on this but basically you don't want your pine in an overly humid environment with excessive heat. I have seen it work great for pine seedlings though when higher humidity and lower intensity is preferable.Just curious.
Also ulterior motive in that I'd like to accellerate the coming season for a special tree that could use some sun.
