How this works

It’s a free research tool. Each report pulls public information from a brand’s own website, labels and published material, dated the day we checked, and every fact links to its source so you can check it yourself. Rates are as printed on each company’s own pages; we don’t show prices. Products, rates and claims change, so confirm with the manufacturer before you change anything. We’re not affiliated with or endorsed by any brand here. Spotted something out of date? nathan@bloomyellowbottles.com

Reading the results

Four questions, straight answers

1. If I add this, am I doubling up?

The recipe matches every product on the job it does in a grow (base feed, roots, flip, bulking, cal-mag, silica and so on), not on NPK. When two or more products in your recipe list the same job, they show under Possible doubling up with one line: these both list a product for this job, so check the labels and plan your rates. It’s not a verdict, just a flag to look closer.

On a brand’s own report you’ll see three tags: Keep (a job Bloom has no product for, or their base), Bloom fits (a job their range doesn’t list) and Let’s talk (both have a product for the same job).

2. Will it affect the other products in my tank?

We don’t test mixes, so there’s no compatibility or safe-to-mix call here. What you get is each product’s job, timing and rate exactly as the maker prints it, with the source linked. Some makers print their own mixing notes and those sit on their pages. For anything about mixing, go by the labels and ask the maker.

3. Do I need to change my rates or timing?

Brands count rates differently: ml per gallon, ml per litre, grams per gallon, per feed, weekly, once a tank. The recipe shows each rate as printed and doesn’t squash them into one number. Bloom’s rates are ml per litre on a weekly feed chart. Each report’s Dose basis section explains how that brand counts, and any conversion on it is shown with the maths. One US gallon is 3.785 L.

4. Where does each bottle sit, week by week?

The week-by-week map lines every product up on the same seven stages: Root, Veg, Flip, Flower 3–4, Flower 5+, Last 2 weeks and Flush. Solid bars come straight from a feed chart or product page. Pale bars mean the window tapers, varies by label, or the bottle is used as needed. Striped bars mean every other watering. Products with no stated timing say so instead of guessing.
