Crazy Hills is a small, fully organic nutrient range built on one idea: feed the soil life and let it feed the plant. Five products cover a complete cycle in coco or soil, there are no grower levels to choose between, and there is only one chart to follow.
- Upthrive: the grow feed. It runs from week one, peaks in early flower and tapers out by the middle of bloom.
- Élan: the booster, and the product doing most of the work on this chart. It climbs steadily through flower and peaks in bloom week six.
- Spark: the flowering stimulant, ramping alongside Élan on the same curve. Browse all flowering boosters.
- Prosper: the bloom feed. It starts in late veg and carries the flowering weeks through to the finish.
- Kick Off: a beneficial microbe and Trichoderma root inoculant rather than a feed. See more beneficials and bacteria.
- Kits: the Explorer Pack to try the range, and the Full Range 1L Kit for a complete run in one order.
Why choose Crazy Hills?
It is genuinely organic rather than organic-leaning, and it is short. Four feeds and an inoculant is the entire programme, in a market where a complete chart often runs to eight or nine bottles. Fewer things in the tank means fewer things to get wrong.
The trade-off is that you feed by eye rather than by meter. Crazy Hills publish no target EC, and that is deliberate: a meter reads dissolved salts, and much of an organic feed is not in solution as salt at the moment you measure it. Growers who like a number on a screen find that uncomfortable. Anyone who has run organics before will recognise it.
Crazy Hills FAQs
Why is there no target EC?
Because they do not publish one, and a made-up number on an organic feed would be worse than a blank. Read the plant and the runoff instead. Our Crazy Hills feed chart page explains the reasoning in full.
What pH should I be running?
5.8 to 6.2 through veg, and 6.0 to 6.5 in bloom.
Do I actually need Kick Off?
It is the one product here you could reasonably run without, because it is an inoculant rather than a feed. It is also the only row on the chart that does not ramp: a flat dose the whole way, since you are topping up a population rather than feeding a plant that keeps getting bigger. If your medium already carries good biology you may not need it.
Can I run Crazy Hills in coco?
Yes. The same chart covers coco and soil, which is one of the reasons the range stays as short as it does.
