Growth boosters
The general-purpose bottles that go in the tank through the growth stage.
Foliar sprays
Fed through the leaf, which gets past a root zone that is not keeping up.
Seaweed, fish and organic tonics
Plant and marine extracts rather than mineral salts.
Vitamins, aminos and microbes
For stress, transplanting and anything else that has checked the plant.
Silicon and stem strength
Stiffer cell walls, which matters most under strong light and heavy air movement.
The full range
Vegetative boosters for stronger roots and faster growth
Veg boosters sit alongside your base feed rather than replacing it, adding the amino acids, humic acid, silicon or beneficial microbes that push root mass, stem thickness and node spacing before you flip to flower. The bigger and more even the plant is going into flower, the more it can carry through to harvest, which is why most growers add at least one veg-stage booster even on a tight budget.
Mycorrhizal inoculants like Great White only work if applied early — they colonise the root zone as roots form, so dose at transplant rather than mid-veg. Silicon products such as Growth Technology Liquid Silicon thicken cell walls and are worth running from week one through to the last week of flower, typically 0.5 to 1ml/L. Amino and vitamin blends like House & Garden Amino Treatment or BioBizz Alg-A-Mic reduce transplant stress and are handy after any repot.

Coco growers should keep an eye on total EC when stacking more than one booster on top of a base feed — add one at a time and watch run-off before layering a second. Our feeding in coco guide has target EC ranges by week. Pair any veg booster with a base feed from the same or a compatible range, and see root stimulators for products aimed specifically at clones and transplants rather than established plants.
