RH and temps are the biggest threats to growing in the desert, but it can be done with the right cultivar... sativas do poorly in arid climate though, but you can grow a top-notch indica bud... I have a precious strain bred in Santa Clarita valley, so IDC much about the heat
Outdoor weed will always be the best. The problem is people often butcher outdoor plants growing them like you’re not supposed to do... and yeah the wrong climate makes it much harder, so I should’ve said sungrown weed grown properly will always be better... I’ve been trying many tricks personally, but I just can’t match my outdoor stuff, it’s next to impossible imo.
Indica's in the heat you say?
