Yeah bro. The only advice you'll ever need. Don't listen to absolute grade-D chucklefucks online. You can see peoples' crops. You can see peoples' rosin. Most of these folks on the big 3 (and now Reddit I guess) grow forum type places are filled to the brim with people vacuuming off spider mites and smoking it, smoking guttation sugars in dab rigs, not washing their outdoor, running tester beans and whitelabel garbagio. Then they'll be on here trying their best to be involved helping other people. Remember how statistics work. If you are slightly above average intelligence, say 60th percentile... That means that your chances of the next person you talk to being dumber than you went up ~20%... Some people are on here brewing 55 gallons of teas without doing protozoa counts on slides. Some people on here get pressed so hard about their crops that for some reason they're spending a band on a potency tester the next week. You still get the off-handed chirality and the flushing boo-hooers and all types of clowns with all types of bro-science. Then you got the geriatric folks talking about how much they did in the 1900s or whatever the fuck with the dinosaurs before the meteor. In the middle of all that, you have shining beacons of science and technique out there. Folks that bang it hard and know what they're talking about, and can actually walk the walk too. Find them, make every crop better than the last, and you'll be on here beefing with these kids in no time (just don't ever ask them to do any better on their crops at that point, because you'll offend). So, I guess that is a long-winded way of saying that you wanting an actual zaza crop is gonna make you not-friends with 9/10 people on here with their tester seeds and anecdotes.
Anything modern genetics, strong lights dialed in on the canopy, any number of countless nutrient lines or do your own. There are certainly bottles out there still worth buying and shipping the liquid. Most solid lines in the past 5 years are just AG salts meant for dirty fields of ethanol crop corn...so if you salts cost you 1 penny per gallon, there is a reason for it. Heavy 16 and VPS are some of the lines you'd see in industry for the folks pulling za. I lean VPS these days. People boohoo bottles but they're clownses overwhelmingly. Like there are no ammonical nitrogen sources in the flowering for VPS. They have a real phd chemist doing like double proton salts to prove where their salts are uptaken into. Like ish nobody else is doing. Other direction for me (outdoors) is GrowWithGrease. But again, any nutrient line of any origin that isn't bottom tier is gonna get you there, with small differences.
At the end of the day, this is an annual that makes secondaries we like. Treat it like any other crop we do that for when we want prize or competition plants (don't grow trash bud sites out).
