well one of the guys in that community uses blue light saturation directly focused on the stem of the plant. the blue light slows the growth of the plant in the vertical while allowing all the branches to grow normally. forget that user's name but he has done some cool stuff with cannabis and...

google space buckets, i've seen a few tsimilar to what you describe.

Here was my first attempt at intra/lower canopy lighting. on paper I've revised this design a bit but since moving I have yet to start my grow up again so I haven't actually built version 2 yet. the pvc 'pole light' in the below pic - i call them bud sabers. http://imgur.com/EH219DU Was...

omg thank you. i've had these v29s for 2 months now and haven't put them to use yet. in part cause i'm a slacker but also just couldn't find a reflector so thank you very much.

Hi, I have 9 x V29s @4K on the way. I was hoping to use the HLG-240H-C2100 but can't seem to find anyone with stock. The build will be actively cooled HSUSA 5.88" heatsinks with 3 V29s evenly spaced. If I have to use single drives - I mean I can but that increases the cost etc. Is there any...
