Hi All,
I have been growing tomatoes in my backyard for a few years. But tomato is a seasonal crop and doesn’t grow when it’s summer and temperature goes above 30 degree celsius. So this year I have made a polyhouse for growing tomatoes. I have setup a fogging system in it with ventilation fans to cool down the heat.
Now the problem is that temperature goes down for a few degrees and becomes 28 - 29 C. This temperature is fine in daytime but at night tomatoes prefer temperature between 18 - 21C. No matter how much i run my fogging system or fan and pad system, the temperature doesn’t go below 27 C at night. And thats killing my tomato plants.
I see some flowers but flowers abort and don’t turn into fruits due to hot nights.
What do you guys do to cool down polyhouse at night?
