first time grow help with conditions

hi guys and happy to find you. its my first grow and i need some help regarding sunlight and heat . i have 3 autoflowering girls in pots growing outside . i dont know if the heat is too much for them . i live in greece . the pants are exposed to really strong direct sunlight reaching temps of 30-40 C with humidity around 25-30 . offcourse i water them often and till now i havent had a single issue . i am at week 4 . but as the summer and sun gets more intense i worry about them . should i be moving them into shade ? should i be changing spots for direct sunlight? should i be spraying them often? please provide me with info . also i need to tell you that after 8-9 o clock i am moving them inside a tent with strong cfls untill the morning sun where i move them back outside. in the tent i emulate same conditions regarding temp and i give them a bit more humidity around the 40s. is that a good practise or is making more harm? i will be gratefull for any help. thanks
