Description

Step 1 · Soil conditioner

Feed your soil. Build happy roots.

Millions of beneficial bacteria and fungi live in healthy soil — they keep pH in check and help plants absorb nutrients. Many potting soils are lacking in this department.

Start feeds those organisms with organic sea kelp and builds a mycorrhizal network that protects roots from drought and improves water and nutrient uptake.

What Start does

Living soil

Feeds soil microbes

Kelp is packed with micronutrients, amino acids and natural growth hormones that feed beneficial bacteria.

Roots

Builds mycorrhizae

Spores in contact with roots grow a fungal network that protects roots and improves uptake.

Seedlings

Fast establishment

Getting these elements in early helps young plants build a strong root zone quickly.

How to use Start

1

Before transplanting

Mix 3 scoops into the soil around the root ball — mycorrhizae grow best in direct contact with roots.

2

Top-dress monthly

Sprinkle 3 scoops on the soil surface once a month to keep feeding beneficial bacteria.

3

Water as usual

Start works alongside Grow and Bloom — keep following the weekly feeding chart.

Mycorrhizae

This fungus grows symbiotically with cannabis. Close to the roots, the spores grow a structure that protects roots from drought while improving nutrient and water uptake.

Brown sea kelp

Not high in NPK, but packed with micronutrients, growth hormones and amino acids. Happy microbes create an ideal environment for nutrient availability.

    It did cause a little bit of nutrient burn.
