CocoCalc

CocoCalc turns the published CANNA Coco grow schedule into a mix you can actually pour. Set your batch size and growth phase, and it tells you how many millilitres of each bottle to add, the EC to aim for, the pH range to hold, and the order to mix in. - Doses for every stage from rooting through flush to harvest - Target EC shown in mS/cm, ppm·500 or ppm·700 to match your meter - Accounts for your source-water EC - Tell it which bottles you own; the recipe leaves out the rest - Mix order and pH guidance on every recipe - Rough stage length and light schedule at a glance - Works completely offline. No account, no network, no analytics, no ads. CocoCalc is an independent tool. It is not affiliated with, endorsed by, or sponsored by CANNA. "CANNA" and all product names are trademarks of their respective owners, used only to identify the products this calculator doses. Doses are guidance only, always verify EC and pH with your own meter and follow the instructions on your bottles.
