Kratky Hydroponic Basil

A & B was just the cheapest powders I could find at the time. Any premixed liquid is much more expensive to buy and ship. This is the stuff I have - https://www.homeofhydroponics.co.uk/shop...d-complete - 1kg makes 10 litres of stock solution, which in turn (at 7.5ml/L) makes 1333 litres of growing solution. They and most others selling powders are just repackaging big 25kg bags of Yara fertiliser (like this https://www.yara.co.uk/crop-nutrition/fe...lon-brown/), but 1kg of each is probably going to last me years anyway.

The 55mm net pots I got 2nd hand off eBay from a cactus nursery. The clay pebbles also off eBay - https://www.ebay.co.uk/itm/264204173260?...3763054316 - there may be cheaper available. There are alternatives to clay pebbles, but I like them because they are reusable.

I don't have a pH or EC meter (cheap ones are rubbish, good ones are expensive), or use any pH up/down solutions. The tap water here has been fine to grow in without needing anything else but the nutrients.
