Grower Q&A’s: Measuring Nutrients for a Single Bucket DWC

Grower Q&A’s: Measuring Nutrients for a Single Bucket DWC

Tony from Vermont asks, “When I’m growing a single plant in a DWC bucket, how am I suppose to measure nutrients? The only charts I have are for big ol’ reservoirs.”

Excellent question, Toni! Thankfully scaling down is much easier than rounding up, so first, calculate the ratio of nutrients to the amount of water the chart tells you. Then take the size of your bucket and scale it to the overall reservoir size recommended on your chart. From there you’ll be able to scale down how much nutrients you’ll need. That’s the easy part.


The next part is going to be little tricky: we recommend using a syringe to add nutrients by such a small measurement (remember: this will be in mL, so chances are it’s going to be a very low amount you need.). Because there are air bubbles that will be in the syringe, give yourself an extra 2mL of the solution to account for a margin of error. For example, if your new solution calls for 3mL, fill your syringe with 5ml. Squirt 1mL out and make sure all of the bubbles are gone. Then fill the bucket with the number of nutrients you need- that should give you about 1ml left of nutrient solution to toss out.
The trick is to make sure you have a little room for error because when you’re growing a single plant all nutrients count. Too little and your plant will starve, too much and your nutrients will overpower that plant.
