At day 20 I switched to flowering and sent my light schedule to 12/12 hours of light/darkness, therefore this is the first week of flowering now. I know that these plants from seeds are still to immature to switch to flowering directly, but they will grow slower with 12/12 until they are old enough to flower. This should happen when they are appr. 4 weeks old from germination, then they will be mature enough to be able to flower. I do this, because the Growfor.Life-Closet is limited in its heigth and I want compact and short plants at the end, so i can keep a minimum distance to the LED-lights from SANlight, which are built into the closet. The minimum distance should be appr. 25 cm from the canopy. At Day 25 the biggest three plants (=Double Dutch from Serious Seeds and OG-Kush from Humboldt-Seeds) have grown so many leaves that they start to touch each other and condensed water is building up between them, the plants seem to sweat. This means I have to defoliate the plants again in order to get a better airflow and also to let the light penetrate deeper into the canopy. You can see a video-tutorial for defoliation I made on Day 25. The scissors I use in the video came WITH the closet, they have a special anti-sticky coating and work like a TREAT! During the defoliation I recognize that one sidebranch of a Double Dutch plant is TRIFOLIATE (see in pics!), this means each node grows three instead of two leaves and sidebranches out of it. That is a rare occurrence in cannabis and can be seen like finding a 4-leafed clover. Although this should mean good luck, I also realize more and more fungus gnats flying around and put some sticky yellow strips (=sticky traps for insects) inside the closet. The plants also seem to get a little bit lighter in their green color in general, therefore I decide to start adding nutrients (=PLAGRON-TERRA-BLOOM) to my waterings now. All in all the plants grow like hell (the biggest one is appr. 30 cm tall at the end of week4) and develop excellently...I LOVE THE EXPERIENCE WITH MY GROWFOR.LIFE-CLOSET until now!
