So i am brand new to co co coir grow. I am used to kratky just water and nutrients in a bucket and plant grows above lid and roots drink the nutrient rich water. So no issues, waiting on a fan to help with strengthening the stem and roots. I am currently watering with nutrition once everyday normally around 9pm. (10am lights off 4pm lights on) The amount of water i give is currently 300ml. The important thing is the coconis never dry. So far 300ml is good. I think i will up the water to 500ml just to keep is nice and moist.
