9 plants in 1m² / 3 Ztrawberry

it grows so fast. The lower leaves are shaded and away from the light. So I cut them as the plant gets taller I really don't have a good setup to be able to clean my roots. I tried this week anyway. I watered each pot with 2L (not enough I think :/) of water at 450PPM PH: 7 then after I gave 1L of water at 900PM PH: 5.5. There was a big puddle in the room afterwards. But it wasn't that hard to clean up after all. In 5 minutes with a rag and a bucket ------------------------------------------------ -Daytime temperature: 24-29°C -Night temperature: 22-27°C -Humidity: 50-75% ( Too high but it's hard to lower it... I need advice please contact me if you have :) ) -Lamp: Mars Hydro FC3000. intensity 80% at 40cm from the top leaves -Room: Mars Hydro 100x100x180cm -Extractor: Mars hydro 402 CFM Max. power 3/10 -Substrate : 70% coco, 25% perlite, 5% vermiculite.
