Temperature

Hello So first with the battle of heat i would recommend changing the 24 hours light to either 20/4 or 18/6 it will cool things down and let the plants rest. You can consider an ac unit or cooler but that does take energy. Otherwise just keep the airflow up constantly, intake fan, exhaust fan and oscillating fans inside the space. You can look into using a silica supplement and kelp extract to help build the plants defense against these stresses too. If you can't cool the outer room down to bring in cool air, then just keep the exchange up, reduce the lights, and keep the roots cool...light colored pots, container with stones and a bit of cold water, water with cold water, just some way of making the plant think its colder than it is. Happy growing. ✌️
