Three Ways to Work With Us

Sampling, a season-long plan, or a blended extract — each meets growers at a different starting point.

Choosing Where to Start

Not every grower needs the same thing. Some want to know what their soil is holding before they touch anything. Others already have that picture and want a schedule to follow. Others have one demanding crop, like tomatoes, and want a feed built specifically for it. Below is a plain look at each option — no pressure to pick more than you need.

How to Choose

If you've never had your beds tested, sampling is a sensible starting point. If you already know your soil and just want a calendar to follow, the seasonal plan does that work for you. If your main concern is one demanding crop, especially something like tomatoes once flowering starts, blended extract dosed for fruiting crops is likely the closest fit.

If you're unsure, tell us what you're growing and roughly how large your plot is — we're glad to suggest a starting point rather than leave you to guess.

What Every Offer Includes

Regardless of which offer you choose, you'll get a written record you can keep, a plain explanation in place of jargon, and a candid note on what the service can't do for your particular bed. We'd rather under-promise here than have a grower disappointed by a result we didn't set up correctly from the start.

Value and Investment

Prices above reflect the time spent reading your beds and preparing material specific to them, not a flat-rate product. There's no subscription and no recurring charge — each offer is a standalone service you return to when it suits your season.

Questions Before You Decide

Can I combine more than one offer?

Yes — many growers start with sampling, then move to a feeding plan or extract blending once results come back.

Do I need sampling before ordering extract?

It isn't required, but it helps us dose more precisely. Without it we work from your description of the plot.

What if my plot is larger than 400m²?

Get in touch and we'll talk through how the service scope would need to adjust for your size.

Is there support once I have the plan or extract?

Yes, questions during the season are part of the arrangement, not a separate charge.

Not Sure Which Fits?

Tell us about your plot and crops, and we'll suggest a sensible starting point.
