I really enjoyed this book as a beginner[1]. I was seriously thinking about getting this [2]. For the price, it seemed very reasonable compared to making my own. I would of gotten it if I live in a more permanent location. I got an Aerogarden to try out but the light is so damn bright. I don't have any place in my apartment that fits it without blinding us throughout the night.
I also considered a Lettuce Grow (beautiful industrial design). Ultimately, I went with a Mr Stacky Smart Farm instead, which is significantly cheaper: https://www.amazon.com/dp/B06VSHBNXS/ref=cm_sw_r_cp_apa_i_bH.... Would recommend it, have had great success so far.
