Hey, this is Josh with Growlink and in today's walkthrough we'll be going over how to make a dosing recipe within Growlink Portal 2.0.
To use a dosing recipe, you would need to have one of our Growlink Fertigation Skids, which is a manifold of pumps and sensors that allows you to intelligently feed your plants based on custom user-made recipes.
To start, you'd log into the Growing Portal 2.0 and then go to your central feed system.
In this case, we'll go to our example controller that's been set up as a central feed system.
When you're at the dashboard of your central feed system, up at the top you'll see a tab called Dosing Recipes.
This is where all your user configured dosing recipes are stored.
Once in the Dosing Recipes tab, it will display every dosing recipe that you have made and give you the ability to add new dosing recipes.
Up in the top right of the webpage, If we hit ‘Add Dosing Recipe’, it'll add a brand new dosing recipe to the controller's configuration.
In the pop-up form that populates, there's a recipe name that we can input, a target TDD and Target pH field, a scale by bar that we can use to scale the parts of this recipe, and then specific pumps that can be utilized to hit a target injection volume.
We're going to start by giving this recipe a name, in this case a flower recipe, and then we're going to put in injection volumes for the desired targets.
If we want to hit for each pump for the PH Up, we're going to try and hit around 0.2 mils per gallon, around 10 mils per gallon for part A, 10 mL per gallon for Part B, and 10 mL per gallon for part C, as a rough example.
What these injection volumes do is take the maximum output of the pump, compare it with the current flow rate that's being called, and try to adjust the throttle rates of the pump to hit these injection volumes consistently.
If we move the scale by bar up and down, we'll note that the actual injection volume being called in the recipe does change by that amount.
If we wanted to exclude a pump from the scaling, we can click this toggle bar on the right called Exclude from Scaling, and you'll see that clicking that moves it back to its base injection volume. This can be very handy for making small tweaks to an existing recipe so that you're able to hit your desired target.
Once you have your dosing recipe dialed in, you could specify a target pH or a target TDs value so that if there's any slight variations in your base water, if you're using say charcoal filtered water or city water, that an algorithm can then slightly adjust these injection volumes over time during a feed to hit the desired TDS value.
It's important to make sure that your dosing recipe is dialed in before setting these targets as these are just a way to nudge these injection volumes in the right direction and not a substitute for setting up a properly configured dosing recipe.
Once you have this configured, you can hit Add Recipe and then update the controller which will then push this configuration of a new recipe to your central feed system and you can make subsequent rules that call this dosing recipe in an effort to ensure that this dosing recipe hits your desired TDS and pH requirements for your feeds.
This concludes how you make a dosing recipe within Portal 2.0.
