Comparisons
Side-by-side decisions between methods, crops and equipment, with the trade-offs and their sources made explicit.
Kratky vs DWC for lettuce: pick by power, season and scale
Both methods hang lettuce roots in stored nutrient solution; they differ in where oxygen comes from, how much water each plant needs on day one and what fails first.
7 min + guided practice →ComparisonsNFT or DWC for leafy greens: flowing film or still bath
Compare a sloped channel carrying a thin film with an aerated tank of standing solution: outage behaviour, root temperature and oxygen, footprint, harvest and cleaning.
8 min + guided practice →ComparisonsDutch buckets vs ebb and flow for tomatoes
Decide whether drip-fed buckets or a flood-and-drain table should carry your tomatoes, judged on root volume, irrigation control, shared water and access.

A first-system decision between a mineral-fed reservoir and a coupled fish-and-plant loop, made on startup time, inputs, pH, animal duties and failure speed.
7 min + guided practice →ComparisonsAeroponics vs NFT and DWC: what a timed spray changes
A low-pressure spray leaves roots in air between wettings; compare oxygen access, what a stopped pump leaves at the root, clogging, cleaning and crop fit with a nutrient film and an aerated bath.
8 min + guided practice →ComparisonsReady-made kits vs DIY hydroponics: sites, light, pods and repairs
A boxed countertop garden and a drilled bucket meet the same needs; they differ in who chooses the light, the consumables, the meter and the spares.
