Well, today was the last day veging. I defoliated the lower 20%, switched on the red LEDs and set the timer to 12h. I activated the 2nd fan inside the box and also switched on the mini fan connected to the cooled hood. I'll leave it open until the stretch or the smell begins. As soon as there's any smell, I'll close the system by adding the glass shield. Also, I'll save the resulting temperature drop for the later weeks so... let's see... Nutrients added: about nothing. I read somewhere you should flush the plants before the switch so I just feed a normal quantity of water with only a bit of nutrients. It's around a 1/20th of the recommended dose maybe. Let the adventure begin!
