Apparently 40 C peak temperature was too much for CBD Rich Candy seedlings. I brought them in and nurse them in airconditioned room. They are in my computer grow case with 6,500 K 32 watts home lighting LED. The light intensity is only about 5,000 lux at 18 hours schedule.
With these mild conditions, the two remaining plants kept going. At this point, they are smaller and slower than other plants for sure. After three weeks, they look like one week old plants. Nonetheless, these are photoperiod. And all they need to recover is just time.
CBD Rich Candy were not bred for hot climate. There are local CBD strains. However, local stuffs are three meter tall with half CBD production. And they are not practical for small garden growing.
I still haven’t given them any more fertilizer during the past two weeks.
And with only tiniest amount of nutrients, conditions are not adequate. On the other hand, the weather outside is getting cooler with overcast sky and rain in the forecast. So, I am moving the seedlings to brave the coming rain outside. Should be the right time to condition the plants.
Actually, I do run my plants through the gauntlet on my phenotype sorting round. And I grow would only the survivors. If there are survivors. To be honest, keeping only the strongest genetics is my main secret for having healthy and productive plants.
@Med_in_Tropic, ok let's see..
It for sure needs fabric pot for cooling.
Soil should have no new
organic ferts at that temp especially.
Shade only no hot reflective areas either.
Watering should only be done with ice cubes (im serious). That would save most of them.
😀😀😀😀😀😀 yes @GYOweed, master of the desert, years later is still better than never. 😆😆😆😆
I live in a big city with heat island. There are parts of Thailand that is a notch hotter.
@Med_in_Tropic, well holy damn i thought only parts China has super high temp and rh.
Well id tell you the fix but you dont listen to me anways until years later :(
