Disagree with almost everything posted.
No need for air-con, it's been the coldest year I've ever known in Thailand.
But Thai strains or western strains? There's a big difference.
Started lots off Thai seeds this year, none of them liked being inside, all looked a bit yellow.
Put them outside once they were big enough to survive the slugs and snails, and they're all going gangbusters and greened up. Just started flowering (one deader out of 15).
Back to OP,
Got three western photo fem strains going in my tent (Tropical Punch, Bubblegummer, Cheeselicious) growing well and totally green but still in the cloning stage (same growing conditions as the Thai strains but much greener). No air-con, tent open HLG240 light plus Quantum boards (about 10Kbht for Mars Hydro 2x4 tent, and HLG240 light).
The most important part of your indoor grow is the light.
