greenhouse gunna get too hot?

im growing in my greenhouse in my backyard and i just heard that even with the vents open its going to get too hot in there for them? right now its still spring so their ok but i really dont want to kill them. I was thinking a fan might help but idk this is really the only place i have to put them and ide like to make it work. any ideas would be helpful

bumpppppppp

if you can get fans in there that would most likely be alright. It would also prevent the air from getting to humid and growing mold. I would say try fans and check the temp in the greenhouse. depending on the strain the max temp can vary. Some plants can be grown in the hottest of locals, but other would suffer in temps above 85 f.
