What's the optimal temperature for Lophophora?

I know they tolerate upwards of 43C in the wild, but is that where optimal growth occurs? I imagine their metabolisms are wired for heat... though I don't know to what degree. Also, is a cooler soil temperature a concern or is that less important?
As far as seedlings go, can they tolerate baking ~38C so long as they're not being blasted with sun? Will they excel under those parameters?
I want to make them stronger as fast as I can, but I don't want to kill them in the process. Beginnings are such delicate times.

seedlings imo are a little more sensitive to sun than are older lophs. seedling under fluorescents for a year or 2 is good. you don't want to much sun as the turn red.
older ones like mine, are growing VERY well in the over 100f temps we have been having. no water for awhile and they still grow which means the hotter the better.
to me slow growth is often better. you don't want none of the cultivated fat bastards around or atleast i don't. they look so weird. slow and natural is how i like em.

mine love the temp range of 20c - 30c, at least that's when they do their growing. then again the ones i had in the greenhouse did just as well in 30c - 35c. they still grow when i bring them indoors for the winter where the temp is around 20c.
i would say around 30c is something like the optimal, no scientific evidence to back up what i say and other external factos obviously play a role. this is just my gut feeling on the subject

we have very eratic summers here man, the hottest temp i have known where i live is 38c but that was an extremely hot summer, 2005 or 2006. then 2007 and 2008 were complete washouts, it rained all summer due to the jet stream being further south than it usually is! the jet stream should go north of the uk during the summer months and pull nice weather up from southern europe, but in the years where it moves further south it brings unsettled low pressure weather systems down from the arctic and from the atlantic.
amount of rainfall really depends on what part of the country you live in and where the jet stream is located. west (atlantic) coast sees most of the rainfall as generally speaking most of englands weather comes from that direction. i live near the east coast in one of the driest areas of the country where annual rainfall is very low, only about 600mm. additionally this area is surrounded by high ground so most of the rain gets dumped on the mountains before it gets here

Climate and Weather As a generalisation, Lincolnshire's 'eastern' location provides for a relatively drier, warmer and sunnier climate. Within the County, localised weather conditions are heavily influenced by the proximity of the North Sea, uplands, and the Lincolnshire Wolds.
Within the United Kingdom as a whole, average annual rainfall at specific sites ranges from 500 mm - 2,400 mm. Lincolnshire, at the lower end of this scale, is one of the driest areas of the country (annual mean rainfall at Lincoln is 577mm).
personally speaking "it rains alot in england" is a myth to me

Hoticulture, as the experienced greenthumb we know you are, you should know that optimal parameters for growing plants are like a gray territory.
People ask - how much water should I give to my plant? There's no exact answer for that. I'd say the same goes for temperature.
We know there's an upper and a lower value limits but I think the whole spectrum is what makes it for a healthy growth. AFAIK most cacti need cold winters for good flowering, I don't know what a good temp for growth would be but whatever your summer can supply you should be enough (lophophoras in nature grow under bushes and mesquite so they don't need a LOT of light, they kind of hide themselves there and protect themselves from heat by living with a great percentage of themselves buried to the ground).
So I think there's no exact answer for you sorry.

I agree; optimal environments are dependent on alot of factors, but I can personally attest that they can tolerate up to 120f or 48c. That is the high that the temps reach in my greenhouse, and it stays that way for the better part of the day. In the wild they never experience temps that high, but yeah they can take it without harm, assuming they are acclimated properly of course.

I suppose it makes sense. Cacti are not something I've had a lot of experience with and are out of my botanical comfort zone. For this reason I find myself thinking of them more mechanically, because I've never been around enough to know the tolerances for different species and whatnot. I guess I should sit back, chill, and grow my plants.
The worst part of experience is getting it.

if you dont mind bloated plants (and easier to die) 20C is good. they will grow more or less all day. some greenhouses here get up to 55 and they tolerate it it, but they dont grow as fast. mine are suaulyl around 30C for about 10 months and see temps at the absolute lowest of 6C breifly and grow pretty healthy at that.
light, heat and water can cause problems in certain ratios though
