It's not a sex toy! ;-)

Yup that was me. It worked really well....... 1.2 to 1.5 g/w. A real pleasure to work under too. The CXA's are better though.

Cool new toy!! http://alliedscientificpro.com/shop/worlds-first-smartphone-spectrometer-lighting-passport/

4ea. 3000k ab bin 3070's at 1400ma would rock your tent. The A51 really is not on the same level. (Apples and Oranges) . 2 of them will fit your budget. You won't be disappointed.

Ditto that, the Alpine 11+ is dead quite.

I hate to say it, and I could be wrong......but get out your loop and look for root aphids.

Here is a good place to start as an example of a good design. https://www.cycloptics.com/greenbeams

Your best bet. https://www.rollitup.org/t/diy-led-cree-cxa3070.789575/

Let's do the math. 8 sqft X let's say 30w sqft= 240 watts \ 60 watts per cob at 1400ma=4 cxa3070's s so 4 will work, I'm with the cap'n 6 would be better, but you can fry them if you're not careful.

Call up Arrow and order a 20 pack of 3000k ab bin 3070's and Jamco for 1400ma meanwell drivers and New Egg for heat sinks. I'm running 16 of them over 36 sq ft and it works very well.

Clones!! but way too blue otherwise.

5X5=25x30watts sq ft=750 watts\60 watts per 1400ma=12.5 3070's So you can do with 12 or 13 units.

I'm running 27 watts sq ft.

4 to 6 running at 1400ma.

Consider yourself spoon fed. ;-) https://www.rollitup.org/t/diy-led-cree-cxa3070.789575/ It's kind'a long but this is the best that can be done right now easily.

Stretch and funny flowering foxtailing etc.

Be careful.....the IR in the Foscam cameras are 730nm. Don't leave them on all the time or in auto mode. Manually turn them off and on.

They work really well for veg.

Yup! This is exactly what I'm seeing going from Agro bulbs to 3070's Longer flower time and more stretch. The first harvest was up as well though had to go 5 extra days.
