Dry formats, and why that matters

Almost everything here is a powder or granule. That is a practical advantage rather than a stylistic one: dry product costs a fraction as much to ship as the equivalent liquid, takes up little space, and keeps for a long time in a sealed container. For anyone ordering regularly it changes the economics.

The Roids range

Root Roids. The root inoculant, in 75g and 225g. Applied at the root zone, where contact with root tissue is what makes an inoculant work.

Root Roid Boost. A 500g supporting product for the same part of the cycle.

Fruit Roids. In 100g and 225g, aimed at the flowering and fruiting stage.

Dry nutrients

Go & Grow. The vegetative dry nutrient, 1.5kg.

Bud & Bloom. The flowering dry nutrient, 1.5kg. Together the pair covers a full cycle at a price that compares well against liquid schedules once you account for what you are not paying to ship water.

Working with dry products

Two habits matter. Weigh rather than scoop — a scale reading to a gram or better makes dry nutrient repeatable in a way that eyeballing never is, and digital scales cost little. And dissolve fully before the solution goes anywhere near a pump or dripper; undissolved powder is a blockage waiting to happen.

Stock note: the granular mycorrhizal version of Root Roids is currently unavailable — the 75g and 225g listed above are what can be bought today.

Dr Greenthumbs FAQ's

Cost and practicality. Liquid nutrient is mostly water, and you pay to ship and store that water. Dry product costs a fraction as much to move, takes up far less space, and keeps for a long time sealed. The trade-off is that you have to weigh and dissolve it accurately, which means owning a scale and taking a little more care at mixing time.

A root inoculant supplied in 75g and 225g, applied at the root zone. As with any inoculant, contact with root tissue is what makes it work — placing it in the planting hole or against the root ball achieves far more than scattering it across the surface of the medium. Root Roid Boost is the supporting product in the same part of the cycle.

They are dry base nutrients for the vegetative and flowering stages respectively, both in 1.5kg. Weigh out the quantity rather than scooping it, dissolve it fully in water before feeding, and switch from Go & Grow to Bud & Bloom as the plant moves into flower. Together they cover a complete cycle.

For dry nutrients, effectively yes. Eyeballing a powdered concentrate produces inconsistent feed strength cycle to cycle, and the whole advantage of dry product is undermined if you cannot repeat the mix. A scale reading to a gram is enough for base nutrients; our digital scales collection covers finer resolutions if you need them.

It targets the flowering and fruiting stage, in 100g and 225g. Like the rest of the range it is a dry format, so weigh and dissolve rather than estimating. It sits alongside the Bud & Bloom base rather than replacing it, and is introduced as the plant moves out of vegetative growth.
