Hydroponic Calendar

Hydroponic guides

Hydroponic planting guides

Use these guides to choose what to plant, when to plant it, and which hydroponic system fits each crop before saving the dates in the tracker. Each guide is designed to end with a practical planting action, not just another article to read.

Use month guides

Month guides help you choose a realistic indoor rotation when you are not sure what to start next.

Use crop guides

Crop guides give the seed-to-harvest timeline, pH/EC estimates, system fit, spacing, and common mistakes.

Use system guides

System guides show which crops fit Kratky jars, NFT channels, deep water culture, and ebb-and-flow trays.

Use the tracker

The guides are only useful if the dates are saved. Put the planted date in the tracker before the tray gets busy.

Beginner route through the tools

For a first indoor hydroponic setup, do not open every guide at once. Start with one month page, confirm one crop page, then use the system page as a final sanity check before planting. That sequence keeps the decision practical: what fits this month, what fits the crop, and what fits the equipment.

FAQ

Should I start with a month guide, crop guide, or system guide?

Start with a month guide if you do not know what to plant, a crop guide if you already chose the plant, and a system guide if you already bought equipment.

Are these dates outdoor frost-date schedules?

No. These guides are built for indoor hydroponics, so the practical variables are light, room temperature, reservoir size, crop cycle, and system type.

What should I do after reading a guide?

Open the tracker, save the actual planted date, and let the harvest window stay visible while the crop grows.
