Day 77 I'm running out of vertical space for pinus contorta, this weekend i will open the box to move the leds higher and will try to do some decent photos. At this point i've added the Pinus purple matcha to the diary because she's huge and impossible to not notice, should be around 1,5m² almost 150cm tall. Had to do a very risky move and "soft crop" 2 apicals because of burn risk, too close to the leds. I wasn't expeting a freakin' tree like that! Day 79 Jeez plz stop growing in height!! After this shaky video i raised the leds 10 cm, now i'm for real out of space.. I'm adding 10 to 12 liters every day, alternating ro with only silica one day and the other with nutrients. Day 81 Way too much leaves in the lower part of the plants but i really don't want to stress them more than the temperature is already doing (29.3C measured in the upper canopy at 5 cm from the leds). Luckily i've got a lot of airflow, 3 filtered exhaust and 1 huge intake to remove almost the humidity. Despite it all they are pretty healty, no visible burning signs.
