Im fairly new to the growing game, but iv started my first hydro grow with purple rhino seeds and a couple other seeds i picked up from miami tree inn my closet and i would rather not mess up. I built a 4 plant drip system and i am running a 400 watt mh/hps light. Im at about week 2 veg and the leaves are curling upwards so i know there is a humidy problem. I also am experiencing green algae growth on the rapid rooters i have in the hydroton pebbles, harmful?I would like to know the best ways for co2 enrichment, Air circulation, humidity, watering schedules etc. Any tips would be greatly appreciated.
