• nutrient solution I’m currently using :  Masterblend formula . Previously used General Hydroponics Flora series . Only reason for the switch was economics . I have expanded and due to a small budget I had to find a less expensive option . Had very good results from their product . mhpgardener has  an excellent video explaining how to use masterblend for nutrients .


  • The recommended  formula (per 5 gallons of tap water ):
  • 12 grams of Masterblend
  • 12 grams of Calcium Nitrate
  • 6 grams of Magnesium Sulphate (Epsom Salt)

I use the following concentrations :

Seedlings : using 1/2 the above formula 

Lettuce :  using the above formula 

Tomatoes : using 2x the above formula
