DIY Refills for NutraFin CO2 Natural Plant System

[snickle]

Anyone have a recipe?

I just hate paying 6.99 for three little packets of yeast and stabilzer.

 

[Mgamer20o0]

3 cups of white granulated sugar, 1 teaspoon of baking soda, and 1 teaspoon of yeast.

you could do something like that but smaller amount. there are a bunch of different diy co2 formulas.

Those packets are basically yeast and baking soda, so substitute with 1/4 teaspoon yeast and 1 teaspoon baking soda.

Yep I have replaced the sachets with 1/2 teaspoon baking soda, 1/4 teaspoon dried yeast, this mixture produces bubbles for about 2 weeks.

If you have hard water, the baking soda is not necessary. I just add sugar and 1/4 tsp yeast.

Water - 3 parts (not too warm)
Sugar - 1 part, dissolve sugar, then add
Yeast - enough to get started (I'm still working on starting ratio effects).

By using 3:1 water:sugar, the EtOH level gets to dangerous levels just as the yeast runs out of sugar.

Using bigger jugs & same ratios = more CO2, not more time (I'm pretty sure).
