Hydroponic Spinach

[GoodBoy]

I am looking at setting up a hydroponic rail system in my basement using led grow lights and I have a full spectrum fluorescent fixture as well. I am hoping that having my crop in-doors will keep the bugs away.

I just ordered a bunch of materials (clay rocks, small water pump, food grade 1/4" hosing and an led grow light). I am just first getting into this.

Where I live, it costs about $5 for a 10 ounce bag of fresh kosher (bug free - lab grown) spinach. Considering that I consume a bag a day, it adds up to a lot of money. I am hoping this will be cost effective.

Will it be cost effective if I do this as a hobby? Can I expect no bugs? Do infestations occur commonly?

Thanks!
