I don’t own a greenhouse. But that’s beside the point; I am not actually machmir on every single thing on my list, I’m just making a point that there are many kulos which the kashrus agencies use which many individuals don’t. I don’t deny that in some areas commercial products might be superior. But I will point out that the level of supervision in my home is superior!
I don’t know you personally (at least I don’t think so!) but I would probably be more comfortable eating in your home than in many commercial establishments.
