If you are new, the goal is not to build the perfect indoor farm. The goal is to complete one small grow and learn what healthy roots, water level, pH, EC, and light actually look like.
Choose one first system
The easiest first path is a passive Kratky jar or small container. It has no pump, no timer, and fewer parts to troubleshoot. Lettuce and basil are good first crops because they grow quickly and show problems early.
Best beginner combo: lettuce or basil, a wide-mouth jar or small tote, net cup, inert growing media, hydroponic nutrients, a basic pH kit or meter, and a simple LED grow light.
Beginner shopping list
- Container: mason jar, food-safe bucket, or small opaque tote.
- Plant support: net cup plus clay pebbles, coco coir plug, or rockwool starter cube.
- Nutrients: hydroponic nutrient concentrate made for leafy greens or herbs.
- Measurements: pH meter or drops, EC meter if budget allows.
- Light: bright window for herbs if available, or a small LED grow light for consistency.
Your first 7 days
- Pick one crop and one container size.
- Mix nutrients according to the label, starting on the weaker side for seedlings.
- Set the water level so the starter plug or roots can reach moisture.
- Keep the container opaque or wrapped so light does not hit the nutrient solution.
- Check pH after mixing and again after a few days.
- Watch for leaf color, root color, algae, and wilting.
- Write down what changed, even if the plant looks normal.
