Hi there, the heat is a big problem especially in the very early stages when the plants are sensitive. I’ve lost 4 seedlings so far due to the heat :( once they are established they become more hardly as you already know. I keep a thermometer inside the greenhouse, and if the temperature rises above around 28 I bring them outside and sit them on a table I have in the direct sunlight. It’s difficult to have a life really because you are constantly worrying if your plants are too hot or too cold lol I did put a fan inside the greenhouse at one point, but it’s really just circulating hot air as I don’t have a filter or a dehumidifier so it’s abit pointless, just put them outside until the temperature drops, they’ll love it :)
