Totally agree with Dirtbag
As a rookie , I feel like I have more say
For experienced growers, good genetics with perfect environment and perfect PPFD(or the DLI that you guys often mention), I personally think the nutrient solution only accounts for 5-10% of the factors (Good nutrient solution does produce more trichome and
terpenes)and i feel that the good genetics are quite different from the same variety genetics even in the same brand. I have three plants, the same environment / lights height/nutrient solution /same amount of power and watering time, and the other two of them are dark dense buds with purple leaves. The other one is just common. It is quite different from the other two. IMO I can only buy the seeds I can buy, but I can't and can't judge whether the genes are good or bad, but for environmental factors (VPD), I have prepared AC / de/humidifier / heater machine,CO2 equipment that can meet all environmental factors(, the AC and humidifier turned on at the same time in normal weather conditions of Veg, and the dehumidifier and AC always operated almost 24 hours a day in Bloom.), and nutrient solution, I'm more inclined to use the nutrition solution of synganics in the cultivation of synthetic.
But for new growers, as long as they can start to grow, even if a plant produces 20-30g, which it is also a great success.
