Fertilizer
Our Bio-Grow requires to top up weekly, recommended to add in 3-4 days after setting up the system. 2 bags of Bio-Grow can last for 1 month.
For the first week, start with the soup bag, place it directly into the water and shake it like brewing tea, then in the following weeks, just top up the soup bag with additional fertilizer from the second pack (1/3 of it each time) until the soup bag is full before emptying the soup bag.
Tips : The used fertilizer can be poured into soil for additional nutrients.
