Are Heirloom veggies right for commencing gardner's?

I commenced a backyard and composter for the first time this year and it has been without a doubt rewarding, even with some setbacks. I absolutely choose to grow Heirloom greens because I should effortlessly attain GMOs from my groccery store. Are Heirloom veggies tougher to develop for establishing gardner's?

Well, it takes much less effort to grow and also exists the reputation of high quality. In that case, I'm wondering why someone wouldn't want them.

Well, one reason is because they want the same plant in the next generation. In other words, hybrids either won't reproduce or they will make something way different.
