PAR is 15 3 feet from light and 250 at the defuser, still cloady.
What about redirecting Sunlight into your grow room?

Would do well flowering indoor near/at the equator. I guess it depends where you live

in this video here they are using solar to run the whole grow , its a long vid...but the solar grow is the first set up.If you just use solar panels on the roof to power artificial lights, maybe that sort of kind of counts?
You don't preserve the spectrum but it could be seen as the same energy, redirected.
Edit..may be im confused and its later on and doing pumps only..i was drinking during the viewing of this vid

I used to run at night, but I've started running in the day since I got solar panels (and my heat problems under control).
They counteract up to 4kw of electricity usage from going to the power bill, in full sun

I knew it was some ridiculous price.

Can you guys say, quantity discount?
The big tubes they were using would easily replace at least one DE, if not several.

I knew this was only a matter of time, I remember pondering the concept of a "solar shingle" a decade ago when scientist were talking about carbon nano-tubes being a perfect material for such an application. I didnt think anyone could do it with current solar tech. Leave it to Tesla I guess. Figured at least 20 years away.

Bullshit. Canon (better known for cameras) did it over 20 years ago.
The technological underpinnings are no doubt better now, but the idea is definitely not new.

Having thought about this for a few days, I can see the potential for using the tech to develop a hybrid greenhouse approach, with most of the benefits for both free natural lighting and full control of an indoor environment. Although I haven't seen it mentioned, there's a way to shut the light tube down so no light passes through it, isn't there? Gotta have that for photoperiod sensitive plants...

This picture to me is a bit strange.
Thats sunlight not a CFL...that should be at the top of the tent. As it is its just wasting headroom.

I thought the technology had been around for awhile to.
Pretty sure i saw solar tiles that "plug" into each other many years ago.

My guess is that it was not as durable as was originally hoped, and I'm sure it was very expensive. These might have been enough to keep it from being cost effective.

They make bigger ones that do work.

Those solar tube skylights are awesome, it really gives the light an ethereal quality. They are not THAT expensive if you can do the labour yourself.
The technology has advanced quite a bit, nowadays they can even help with dehumidifying, can do 45 degree angles and can be quite long tubes,

IF you look at the website there is a dimmer option.
You can adjust the height look at the video.
