What a pleasure to smell the first fresh weed notes in your room. All nice, except first signs of Calcium deficiency on the bottom leaves of the #2 and G.Z. I still have the light distribution problem with the #1 which is 10cm taller than others. I prefer to get up the light to avoid any burn. I pulverised some L.A.B KNF during the week on the mulch surface to boost organic degradation. I'll put the carbon filter next weekend because a sweety stong smell is arising : it will certainly increase temperature and maybe humidity bc of the airflow reduce. Will see. can't wait :)
