MILLS START 1 LTR

Vegetative-Stage Supplement for Seedlings & Young Plants, 1L

Seedlings and young plants need a different nutrient emphasis than mature plants in full vegetative growth, with root development and branching mattering more than raw nutrient volume at that stage. Mills Start-R is a vegetative-stage supplement combining two types of nitrogen compounds with a blend of seaweed extracts, formulated for use from seedlings and rooted cuttings through early bloom.

This 1L size of Start-R suits home growers or a smaller-scale operation.

About Mills Start-R

Mills Nutrients' lineup runs from Start-R through Basis A and B, C4, Ultimate PK, and Vitalize, covering the plant's full life cycle from seedling to finished bloom, all developed at the company's research and production facility in the Netherlands. Start-R is the system's early-growth supplement, formulated for seedlings and young plants before C4 and Ultimate PK take over in flowering.

Frequently Asked Questions

What is Mills Start-R used for?

It's a supplement formulated for seedlings and young plants during the vegetative stage, supporting root growth and branching. It's meant to run through early growth before a grower shifts to flowering-stage products such as C4.

What is in Start-R?

It contains two types of nitrogen compounds together with a blend of seaweed extracts. That combination targets root and branch development, rather than the flower-stage support C4 and Ultimate PK provide.

How long can I use Start-R?

It can be used from seedlings and rooted cuttings up through the early bloom phase. Once flowering is fully underway, most growers transition to Mills C4 and Ultimate PK instead.

How do I apply Start-R?

Blend it into feed water at the label rate alongside Basis A and B, and consider a lighter dose for very young seedlings that haven't developed a full root system yet. Watch new growth for the first week after any rate change to confirm plants are responding well.

Which size should I choose?

The 1L or 5L bottle covers a home propagation area, 10L or 20L suits a mid-size operation running several trays, and 60L or 200L is sized for a commercial propagation program. Because Start-R only runs through the early growth window, matching the size to one propagation cycle keeps leftover product to a minimum.
