Glasshouse growing

Newbie here. Is glasshouse growing worth a go or are there to many variables to have a decent chance?
Have a large glasshouse and grow plenty of tomatoes and hot peppers. Temps are 20-35 Celsius during the day and drop to about 15 overnight.

Hey man. I've been growing in a polycarb greenhouse for a few years. Well, it is technically a converted high tunnel kit. But it's got water/power and all the usual greenhouse amenities. The main thing I struggle with is the larger temp. swings and the humidity. Especially towards late flowering, whenever fall weather tends to turn cool and wet, inside a greenhouse the cold humidity is really shitty for increasing bud rot potential.

One thing I have been trying and plan to greatly expand upon is putting 55 gallon barrels along the back wall, and filling them with water and 40ml of bleach so they don't grow algae (I typically use creek water, or well water if the creek is out of season.) This has been helping quite a bit with regulating temperature swings from night/day, but I only put enough in this year to affect the plants directly around them.

Additionally I bought some 40% reflective shade cloth and am going to run that along the inside of 2/3 of the roof paneling. The idea with aluminum reflective shade cloth, rather than the black absorptive kind, is that in a greenhouse, it should act to reflect heat away as well as reflect some heat back to the ground, ideally acting as a happy medium in temperature regulation. I'll be experimenting with it next year and if there is interest I will report back.

What sort of glasshouse do you have going on?
Does your glasshouse have power? What sort of water access do you have? How much control over temperature and humidity do you have inside?

I've got a 4mx3m glasshouse. Have power and water to it. I like the idea of the aluminium shade cloth,reckon it would work mint.
