Free Excel Spreadsheets

Great for letting the police know what you have been doing in uk

Some equipment does dump data, as granny mentioned... something that you can output as a txt comma-delimited file then have it linked to spreadsheet table that auto-updates data table / worksheet data from file when you open or when prompted.

here's a nutrient ppm calculator -- you prolly know how to add rows to tables but is setup for up to 10 products as-is... would need to add rows to worksheet tables. edit it change it do whatever you want with it... it's free. May need to do some conversions if not g/gal like my instructions. easy enough to change that if you want. could do nested ifs with a toggle for the type of dosage needed.. yellow = inputs, green = outputs. Gives "molarity" too. The trace stuff shoulda been in millimoles. https://drive.google.com/file/d/1404ph0LPe3XlMwlfJf5LLLy7xRRM0i7I/view?usp=share_link

Nice idea but spreadsheets are fairly easy to develop - the key to them is dumping in the data on a regular basis! The one spreadsheet I've developed for myself tracks the entire grow on a daily basis... calculates the EC, keeps track of the nute solution, VDP, ppm, pH, how much water is being consumed, temps, humidity, what I've done to correct any issues that arise, etc. Keeping track of seed/bud inventory is rather basic. One grower I know even has his spreadsheet calculate the cost of the grow in terms of nutes used, electricity/fuel for heat $$ - not just the cost of the seed or clone. But this is a nice idea for those mathmatically or technology inept!
