If you are going to add blues I would suggest 400nm and 430nm. No need for alot in an area that size, about 20watts is heaps, reds will be a better addition though especially for flowering

I have 4x royal blues: https://www.stevesleds.com/Luxeon-SunPl ... p_354.html

and 3x deep reds: https://www.stevesleds.com/Luxeon-SunPl ... p_353.html

Also using growmau5 puck far red initiator 15min before light go off and 15min after.

White leds have plenty of royal blue as they are, that's why I suggest another colour. 450nm will help with veg though, better to make your spectrum broader next time. The reason why everyone pushes for royal blue isn't because it's best for plants it's because it's by far the most popular colour of led produced. The peak absorbtion for plants in blue is actually at 428nm not 450nm. But 430nm leds are alot more expensive than 450nm

Got it! Thanks for advice. So will use the blues for veg only.

Also, what do you think about max lux? I know PAR meter is more precise but I don´t have one.

What colour are the white strips?

What colour are the white strips?

4x 3500k and 2x 5000k

Without any suppliment colours turned on Lux X 0.014 would be about right could be 10% out though

So that is 70.000lux X 0.014 is 980ppfd right?

[TEKNIK]

Yes about that, it's hard to know exactly without testing the same strips, although they are CRI80 strips spectrums can vary alot in cri80

The cheapest mix I've found good for general use is Jungle Growth, though even it can benefit from some amendments, used in containers. To use as-is, Pro-Mux and Fox Farm stuff is great, just costs an arm and a leg (fine for just a few gallon pots with houseplants). OTOH, I managed to screw up my pH and ruin several otherwise good tomato plants (grew great, but have unrelenting blossom end-rot, and pH seems to be close to 4, somehow), so YMMV on mixing your own to save money .
