Thank you for your opinion, but "most professionals"... Lol, we are definitely not the majority. There is a lot that 3 pictures and a couple sentences don't say. Let me help you understand while keeping it short.
Try to grasp the amount of overhead a clone room, mother room, and the employees to tend them year round. Think commercial scale... propane, electricity, wages, nutes, trays, cubes, etc, etc. Then consider doing all that months before you spend $250,000 to build out another property, while feeling out the market flux in the last 5 years.
I have a pretty good idea, because there is a clone room nextdoor feeding the 80k sqft of recreational greenhouses. This is 1 of I don't know how many properties. We feel it can be worth it for indoor and deps but not feasible for outdoor flower prices.
Then consider the states rec rules and what type of canopies are allow on property. Don't forget about buying registered clones form a registered producer.
The owners have properties that produce industrial hemp seed, hemp flower seed, and cannabis seed. They also own a few dozen dispensaries in 4 states. I keep my nose out of that. Seed is far cheaper for us when building from scratch.
Another aspect is we are putting 10 new strains into the market. Of those strains, we are doing a pheno hunt for next year. This is our process.
FWIW, I just build an manage farms. Selling the product, number crunching, and worrying about it is the owners job.
