OptimusPrime, you've given a quote from Lowryder official description.
And it doesn't say that you achieve less in results with 18 hours. It says SIMILAR

Moreover, I have a surprise for you - here is official GROW GUIDE:

1st quote!
Preferred growing methods
Indoors, Lowryder performs very well in soil mix (pots or beds) or in
soil-less systems, where it can be cultivated from seed to bud in two
months â?? 18 hours of light per day is recommended all the way through.
2nd one!
For best results, place jiffy pellet or plant directly into 1-2
gal.pots. Alternatively, start in 4-inch peat pots, then place
rootbound females into a plant bed after sexing (at approx. 17-20
days) â?? this may result in smaller plants than the first method. Grown
under a 12 to 24 hour/daylight cycle from start to finish. I recommend
18 hours per day; this can be decreased to 16 after the first month with no loss of yield.
What's the Joint Doctor ordered :rasta:
