After initial setup check them after a few hours. Look for signs of plant stress;
curled leave tips, yellowing leaf tips etc. If you see these signs reduce dimmer
by 1/5 turn and monitor.
Flowering cycle
Hang at 16cm to 25cm or 6″ to 10" over the top of the plant canopy for
maximum system efficiency and set the dimmer to 100%
Hang at 16" or 40cm for maximum uniformity and about 5% reduced PAR
reaching the canopy.

How much light plants need for maximum yield
To optimize your grow it is recommended that your plants receive 500-1,000
μmols of PAR light for every m² (PPFD). Less than this and growth rates and
yield will be low.
Growth rates at higher PPFD levels do not justify the extra energy cost and
heat output and the plants require additional CO₂ to utilize the high PAR
intensity
