So, you want to get a growers license in Washington State, let's do the math.
The government wants 25% of the retail value of everything you grow. Let's say an Oz goes for $250 retail in the shops. This is where CO prices are at. The government wants 25% of the retail value of your oz which is 62.50. It also wants 25% of the retail value from the processor and 25% of the retail value from the retailer. The government wants 75% of the $250 oz. That leaves $62.50 per oz that must be shared by the grower, processor and retailer. So the grower ends up with about $21 per oz as does the processor and retailer, assuming the margins are cut equally. Now factor in rent or mortgage, property taxes, lights and equipment, utilities, security, grow media and annual license fees and employees and it's going to be real hard to make a profit and if you do, you must pay income tax on that. The mafia isn't even as greedy as the government. The mafia will allow you to make a profit so they can profit on you. Is this what you want? It makes more sense to grow your own 15 plants, make hash out of it and mail it to your cousins in Iowa or Minnesota. The big winners in all this, if there are any, are going to be the processors because of the low overhead, no lights or electricity, no retail space.
