Mini tent grow

We have a heatwave here so it is a little hot inside my tent (27 Celsius). Im trying to keep the humidity up to 80%. I am with using wet microfibre towels placed inside the tent to help the air stay moist. The light is 50cm above the plant at 35% power (100w LED) and I am getting 200 PPFD. All seeds germinated inside the soil in just 2 days, no paper towel method was used. I planted in premixed soil, which I flushed to lower the pre added nutrients. I just hope the soil isnt too hot with nutes. Any help and tips welcomed in the comments!! I had great results growing outside but inside with tent I have had 2 failed runs in the past so hopefully this one will be OK.
