Description
Organic grow fertiliser that feeds the plant and the soil life
Crazy Hills Upthrive is a plant-based organic grow fertiliser for the vegetative stage, with a balanced NPK of 4-0.5-4 drawn from vinasse – a natural source of nitrogen, potassium and B vitamins – together with cold-pressed seaweed extract, humic acids and natural carbohydrates. It feeds the plant directly and gives the beneficial microbes in the root zone the energy they need, building thick stems, lush foliage and strong roots ahead of flowering. It is 100% plant-based and vegan-friendly.
Key Benefits
- Balanced organic NPK 4-0.5-4 from vinasse for fast, healthy growth
- Feeds soil microbes with natural carbohydrates, so the root zone stays biologically active
- Better nutrient uptake from humic acids working with seaweed extract
- Thick stems, lush foliage and strong roots to carry the plant into bloom
- Prepares plants for flowering with organic potassium
- Plant-based and vegan-friendly – no animal inputs
Slow vegetative growth and a tired root zone
Organic growing depends on soil biology as much as on the feed: if the microbes around the roots have nothing to live on, nutrients stay locked up, root development slows and growth stalls in veg. Upthrive pairs its nitrogen and potassium with the carbohydrates and humic acids that keep that biology working, so nutrient uptake stays strong and plants build the frame they need. Crazy Hills keep it going into the first weeks of bloom, where it continues to feed the microbes and the plant's natural sugar production, before tapering it off.
How to Use
- Vegetative stage: 1 ml per litre in weeks 1–2, 1.5 ml per litre in weeks 3–4.
- Early bloom: 2 ml per litre in weeks 1–2, 1.5 ml in weeks 3–4 and 1 ml in week 5; weeks 6–7 at 1 ml are optional, and none in week 8.
- Pair it with: Crazy Hills Elan and Spark through veg, and Prosper as it takes over in bloom.
- Mixing: add to the water, stir, then check EC and adjust pH to 5.8–6.2 in veg and 6.0–6.5 in bloom.

Frequently Asked Questions
Is Upthrive organic?
It is a 100% plant-based, vegan-friendly organic fertiliser made from vinasse, seaweed extract, humic acids and natural carbohydrates.
Why does it carry on into bloom?
Crazy Hills keep it in the first weeks of flowering to go on feeding the root-zone microbes and the plant's natural sugar production, then taper it to nothing by week 8 as Prosper takes over.
Do I need anything else with it?
For a full programme Crazy Hills run it with Elan (all-round booster) and Spark (seaweed stimulant) in veg, adding Prosper as the bloom fertiliser.
