I have had great success with Nirvana. But mistakes happen. You want to see different pheno types try MSNL Carmelicious. I've grown 7 now all autos. Some are short squat and make huge colas. Some Massive very long tall colas and take 120 days. Some done in 75. Some have long thinner buds but grow massive yields. They all have similar characteristics when smoked but are all a bit different. But they are all amazing.
I jar every plant separate with the exact plant, date jarred, planted, harvested, type lights, time of year etc. Every jar is a bit different and when I smoke I choose the exact plant I want to smoke. So yes pheno types and conditions grown in make a huge difference.
if you want a Nirvana plant that is almost always identical and some of the best smoke you have ever smoked get their Nitro Lemon Haze photo. Cant recommend it enough.
MSNL I like alot. Seedsman is great for variety but for some reason get confiscated more than others. And some seedsman seeds sit a long time so can take longer to germinate. New guy 420 is willing to really work with you. So many others that are good. But with all the constant crossing of strains all companies are going to have seeds that are way off of each other.
Trichomes are tricky. Unless you are growing a "white" strain you never know how many trichs you will get. But never judge a bud until its fully cured and you smoke it. Some of my best smoke is ugly as hell. Airy, not a whole lot of trichs, not pretty colors, low aroma, etc etc. But you better believe I like you if that's what I pull out to smoke with you.
