What? Are you talking about?
This is moronic bitchiness at best -
Growing indoors is an attempt to provide a perfect natural environment. So while the outside might have sun, breeze, air, and rain - indoors has an HPS bulb, a fan, and a guy with a watering can. So I have no idea what in the world your point is.
The idea that the plant will react to higher temperatures in one environment while NOT reacting to them in one that provides all the same "elements" is obviously wrong.
Now,
This is also wrong. He's already well invested in ventilation, and if you bothered to read the entire thread other than the part you thought you could smarmly disagree with, you'd see that not only do his plants look excellent, but he's moving plenty of air. Beating a plant to death with wind is a good way to damage it. Brief temperature spikes to 90F might slow down rapid growth a bit for some strains, but it won't cause any permanent problems.
So, as I said, if he really feels this is a critical concern - which I don't think it is but some ppl are nuts about their plants - then he needs outside ventilation - even if it is just ventilation to the rest of his residence.
Lastly, the OP's concern is detection, and temperature spikes are better than prison.
