Tip 1 _ dimming is the same as moving your light further away. The reverse is also true, if you dim your light you can move it closer. A good way to Take advantage of lower running electricity costs.
Tip 2 _ Cuttings need hardly any light to root. Don't over do it. Literally just 5w of led light at 12 inches away is all you need. Leave it on constantly
Tip 3 _ Seedlings need very little light too when compared to flowering plants. For a reference In the pic attached you'll see a par rating of 250 ppfd , the fixture in use is the ISH150 BR @12 inches from the pot tops. This fixture is dimmed to 40w. Let the plants grow into the intensity they want, it's only a few inch don't worry about stretching. More light could be counter productive.
Tip 4 _ more light doesn't equal faster veg. In veg less is better when using LED 15w per square foot is ample. Too much light will have a negative impact.
Tip 5 _ purple leaf stems can be an early sign of too much light in veg. If you find purple leaf stems dim your light until new growth stays green , and use that power setting as your reference point.
Tip 6 _ when transitioning into flower, slowly increase your lights power over the first 2 weeks of the cycle.
Tip 7 _ if possible utilise Sunrise and Sunset timings for stress free night / day transitions.
