As true as that is, he is not at the level where the 80 stamina gardens will be efficient yet, i mean he mentioned saving up towards his first 50 roll even. At that point you just want to level your girls asap, get some nice helpers and get going. Equipment is nice but you can also get seeds from attacking other people's bosses and for that you need to bring your power up in order to get allies that can spawn those to begin with.
I would guess his level is below 40-50 which means doing the 1-3/2-1 + garden will level him at a decent time compared to the 80 stamina gardens that will give him a lot of downtime. Once his level gets above 50ish and his girls evolved, the 80 stamina gardens will prove more and more efficient, but definitely not now.
