Further analysis of plant PAR reveals peaks of absorption like this:
Chlorophyll A 430, 662
Chlorophyll B 453, 642
Chlorophyll C1 442, 630
Chlorophyll C2 444, 630
Chlorophyll D 401, 455, 696
Chlorophyll F 720
Beta Carotene 450,482
Phycoerthrin 495, 545, 566
Phycocyanin 620
Allophycocaynin 650
Fluorescein 494
Which follows that a LED grow light should contain LEDs at the following nm:
400, 430, 445, 450, 455, 500, 545, 565 (for growth)
620, 630, 640, 660, 700, 720.

Reason being is after growing for my 3 month period one thing I noticed was when I went to flush the salt build up move out of the soil. But never left the walls of the fabric pot. I had so much salt built up on the walls it took me 2 days of soaking them in oxy clean to try get the salt off to use them again. And with that in mind. Where do all your roots end up?? However. My air pots were mind blowing. They were easy to flush and all three of my autos hit 3 feet in 4 weeks. Its completely up to you what you use. All I know is after this grow is done my smart pots are getting retired to out door use for flowers or tomatoes only ! Lol. I guess it all depends on your nutes you use too.

I got flexpots off ebay for much cheaper. 2 gal for 10 of them was like 20 bucks shipped. they seem to be good quality too (so far at least).
you gonna stick with soil for the next grow?
i have a drain to waste going now in coco and decided to try drip clean by house&garden. supposed to help reduce salt buildup.
