My 8hr flowering experiment

In the winter heat is fine but as soon as it warms up I stop the indoor because of the extra cost with the a/c.
If I could cut down to 400 watts and not suffer any yield loss it would be awesome.. Some day I WILL make the change, Its a must ..
I tell people they'll need somewhere between 55-60% of the watts to achieve similar yields as they're used to from HPS.

The real reason to do it is better quality.

Why does running temps in the mid 80s benefit with led?
HID lighting puts out a lot of infrared light which is not seen but felt as heat. Much of the reason LED lighting is more efficient is due to the fact that they emit very little infrared light, so to help the plants transpire water and draw up nutrients it's helpful to run the space warmer. This saves even more on cooling costs since the space doesn't need to be chilled as much for best results.

Keeping temps up in cool months is an overlooked part of growing with leds. I now duct air from floor vent into tent. Leave it the same now with A/C in the summer. Drainage is also in need of an increase with leds in whatever form. Cold roots cause all sorts of troubles and cold wet roots are horrid.

Here's a group shot from today.
I moved the hinduhp and field trip into the front centre spots.

They will need some time to stretch out and I can hopefully remove their high chairs.
Starting to really smell funky now.

The false teeth has a sweet fruity scent that I can't quite describe yet.
Not the biggest buds on her but still yummy looking.

Did some snipping and tying in the veg tent.
Needs another couple days worth I'm sure but things are progressing along.
Pulled a few plants out and took some pics to show what kind of growth I'm seeing with these pcb boards and the glr light cycle.

Great stuff!
Paged through as much as I could mostly enjoying the harvest pics.
Great crystal. I was going to keep my lights at 11.5/12.5.
Now I'm thinking of knocking off an hour each week in the last 2 or 3 weeks.
If you do and u notice something either positive or negative please come back and let me know here or in the reduced hours thread I just started.
I want to get as much info about what worked vs didn't out there so no one needs to just take me for my word.
If we can compile enough data about all the details we may change the way some people think.

Edit:
Almost forgot
Thanks for dropping by and having interest.
