Yup, and the big companies have already figured that out too. Companies like Scotts Miracle Gro are already strongly positioned in the grower supply market.
This is truth in many cases,,,
My great uncle went to Alaska to mine gold.
He got rich up there but not by mining,,,
He got rich by selling equipment/supplies to the other prospectors.
I have a degree in commercial photography,,,
I made my living at it for a lot of years.
But I made more money hosting seminars on photography,,,
And selling sponsored gear and studio supplies,,,
Than I ever did with my camera.
Just sayin',,,
