It also puts undo stress on the plants and they go into survival mode, dropping other functions like fruiting in hopes of just staying alive. Think of it like hiking on hot summers day in the desert, and being given all the water you want to drink. Only instead of cool water it's hot water. This applys to every type of hydroponic system. Although, in an aeroponics system it's a bigger problem. This is because the water is mixed more so with the air. The air temperature will dramatically affect how fast the water temp rises, and ultimately the temperature of the root zone. |
Thanks, looks like its going to be a struggle for me this summer, I have grown in a temperate country and indoors before but where I currently live it doesn't really rain from jun - oct and on the roof where I am growing is about 30 - 45 celcius (85 - 110 f) during summer :/
