House & Garden Feeding Schedule

About House & Garden

House & Garden came out of the Dutch greenhouse tradition, where margins are thin and consistency matters more than marketing. The company's whole approach is built around ingredient purity — nutrients are cold-processed from high-grade raw materials, which is why the bottles stay stable and mix clean.

Growers who switch usually mention the same thing: the feed does what the chart says it will. That predictability is why it is a favourite among people running the same room season after season, and why it is our third-largest brand at 57 products.

The feeding schedules

House & Garden publishes this chart only as a flattened image, with no text layer or PDF to extract, so it was transcribed by eye directly off the linked PDF at native resolution -- each row read against the chart’s own header rather than off one wide crop -- then independently re-read a second time before publishing. A dash means the manufacturer’s own chart calls for nothing that week; “Flush” is the chart’s own 3–5 day water-only period after the final week shown.

The 10-week chart’s original link on this page had gone dead (404), so this download is re-sourced directly from the manufacturer’s own feeding-schedules page at house-garden.us/feeding-schedules rather than left broken. Same transcription method as the 8-week chart above.

† Marked optional on the manufacturer’s own chart. ‡ The manufacturer’s own chart notes: for more significant leaf fade, omit CalMag Powder in the final two weeks shown. Figures as published by House & Garden. Feeding charts are recommendations only. Adjustments may be needed based on environmental conditions, your grow structure, and any additional products you run. Actual results vary.

Lines we carry

  • Cocos A & B — the coco-specific two-part, and their best-known line
  • Aqua Flakes A & B — for recirculating and run-to-waste hydro
  • Soil A & B — for soil and soilless mixes
  • Roots Excelurator — the root-zone additive the brand is famous for
  • Additives — Bud XL, Top Booster, Shooting Powder, Multi Zen, Drip Clean

Reading the schedule

Pick the chart that matches your flowering time rather than compressing a 10-week schedule into 8 — the additive timing is what makes the program work, and Shooting Powder in particular is time-sensitive.

Add A and B separately, and wait between them. It is the single most common mistake with this brand.
