Purps OG, Wi-Fi OG and OG kush in 1 room

This week it is time to transplant the small plants to their final pots/room. They are standing under the Mars Hydro SP3000 on 50% at 60 cm height above the canopy, i'm gonna lower the light in the past weeks and put it slowly to 100% when i switch to flower. i've mixed 60L cocos premium and 10L perlite from Plagron for their final (18L) pots. i drilled some holes in the pots to make the low stress training i'm gonna do on them easier for myself. I also received my new ph/ec meter + soil meter this week from Aquamastertools to make my measurements quicker.
