This isn’t necessarily the case . Shorter veg time equates to a shorter plant, higher output light in too red a spectrum will promote tight node spacing and a bushier plant.
I would recommend fabric pots and depending on the veg time, 5 or 7 gallon. Autos are fine with 3.
35 watts for veg, 50 watts for flower would be my preference. Led’s are very confusing and it’s good you are on top of it now.
I own 8 lights of various manufacture. The best one for veg is the 300 watt Meizhi. But one thing to remember is most of your plants’ veg time takes up very little space. You need the wattage and coverage for flower. That said: these lights are built from obsolete tech and one could do a WHOLE lot better to invest in a quality light now instead of later. I will be replacing all of mine with home built fixtures shortly.
