Equipment and Nutrient Change Tomorrow

Nutrients
We have seen the Generative (aka flowering) stage begin on our Cherry and Roma Tomatoes in the PowerGrower.  Our nutrient solution in the PowerGrower is Canna Aqua Vega, Rhizotonic, and Cannazyme delivered at Canna's published rates.  We will now switch to Canna's Aqua Flores, reduce the Rhizotonic concentration, keep the Cannazyme about the same, and add Boost.  All of these products are available in different size containers (1 liter, 5 liter, etc).  We will continue to follow dosing rates per Canna's literature.

Lesson learned - if you have two big systems like I do, and run successive grows back to back - get the big jugs of nutrients.  You will also need one of those big syringes to get the nutrient out of the big jug (unless you like funnels and big measuring cups).

I have not experimented with other nutrient manufacturers' products, nor am I endorsing any product for any type of financial gain or consideration.  All I can say is that this Canna stuff works extremely well for me while following their recommended dosing and while also using their nutrient additives (like Rhizotonic, Cannazyme, Boost, etc) to the base products of Aqua Vega or Aqua Flores.

Lighting
We will change the HID light bulb above the PowerGrower from Metal Halide (MH) to High Pressure Sodium (HPS).  A metal halide bulb has a high concentration of blue light spectrum and is primarily used during the Vegetative stage.  A high pressure sodium bulb has a high concentration of red light spectrum and is primarily used during the Generative stage.  Either bulb will provide results for you.  If you want the best results, use them during the identified stages, if you can, to improve your results.  The MH bulb in the HID above the AeroFlo36 will remain since those Grow 2 plants remain in the Vegetative stage.
