Indoor growing, measured.
This is a log of what actually happens when you grow vegetables, herbs, chillies and houseplants indoors under LED lights. Different experiments run in different cabinets, all in an apartment rather than a greenhouse. Every guide here comes from a real setup with real sensors, so the numbers you see are actual readings, not guesses, explained with real data and conclusions where there are any.

Greens, herbs, tomatoes and chillies fit in a cabinet like this. Space-hungry crops like corn, potatoes or squash don't.
Real numbers
pH, EC, VPD, temperature and humidity, all logged instead of eyeballed.
Tested here first
Nothing is called "tested" unless it was run in this tent, failures included.
Corrected in public
If a guide turns out wrong, it gets fixed. Reader corrections are welcome.
