I'm not sure if I'm piled in your "old people" box or not. As to your comment "if you can't do it then no one can", well, son, I am doing it. I do do it. My op exceeds his goals every month, brother. If you don't think experience is needed to run a 20k op, you're way too high. Don't forget about $$$$. Our grow op costs $80,000 to set up. We pulled a 100K private line of credit and used 80k before we got on our feet. This 80k includes paying ourselves to build and operate the thing. We were on our feet in just 100 days. Meaning, from the time we started the build until the time we had cured product. We were able to do this because I have friends with big ops who gave us dozens of foot tall killer Bubba that SELLS.s when we were ready. So, with the experience that you deem un-needed, come contacts. That contact shaved 3 months off of our grow schedule, AND started us out with a great strain.
You say experience is not everything. You're right. I would honestly say it's about 85% of what's needed for a successful grow. The other 15% is money. AND, the larger the grow, the MORE experience comes in. BECAUSE, when you have a problem, you have a BIG problem that must be dealt with RIGHT. Failure to do so can cost more MONEY than is available.
I'm curious. If experience is not everything...what is? I mean, a deep wallet can get it done, too. Just pour $$$ into it until you get it right. But, wait...isn't that just experience? All that time and money spent to get it right? I believe it is.
There's a link in my above post to my thread showing EXACTLY what is needed to get these yields. Ours does a little better. But even if I came over with my helper and built the whole thing for you, without EXPERIENCE, it will eventually fail. Most people here have lost a crop. Right? It probably happened when you had less experience. Well, just how many crops can you lose that are worth over $20,000? It's one thing to lose a few plants in a closet grow. Losing a commercial crop is a different story. The lost $$$ has to come from somewhere.
BTW, one of my requirements for any warehouse grow is a 300amp panel. 100 amp 3 phase will work. That's what our current grow has. You have to be very careful with older buildings and pushing panels near their limit. I have some EXPERIENCE in that, as well. LOL It wasn't a fun EXPERIENCE, either.
