I am a first time grower. I keep these two seedlings in the greenhouse at night to maintain humidity and the temperature ranges in the low 90’s during the day. I keep them in direct sunlight. The angle of my house provides me with a 12-12 schedule. They have been undergoing transpiration every night like clock work. Stoma’s look like they are functioning at full capacity. These are auto flowers so the light cycle isn’t a big concern of mine.
They get feed 2-3 tablespoons of 6.0 pH water every day at 1 PM. The water is slightly cooler than room temperature to help cool them.
A few days ago they looked overwatered so I cut down the frequency of waterings and they started to look good again. Today I checked on them and one seems like it might be undergoing heat stress so I added some fans to each plant. Will this help with the high heat and humidity issues? Is there anything I should change?
