House & Garden Cocos - Starter Kit

A Starter Kit for House & Garden's Coco Coir Base Nutrient System

Trying a new coco coir base nutrient usually means committing to a full-size bottle of each part before knowing whether it fits your setup, which is an awkward first step for a grower who just wants to test the system on one grow cycle. The House & Garden Cocos Starter Kit removes that friction by pairing one bottle each of Part A and Part B, the two components of House & Garden's base nutrient formulated for coco coir's cation-exchange behavior, in a single kit.

This kit is sized for a full grow cycle using 15 gallons of feed water weekly across a 2 week vegetative stage and 8 week flowering stage, giving a grower a complete cycle to evaluate the system before committing to larger bottle sizes.

Key Features & Benefits

• One bottle each of Part A and Part B — everything needed to start feeding coco coir with the complete two-part system
• Formulated for coco coir's cation-exchange capacity — accounts for how coco coir holds and releases calcium, magnesium, potassium, and sodium differently than other media
• Sized for a full grow cycle — covers 15 gallons of feed water weekly across a 2 week vegetative stage and 8 week flowering stage
• Sized for first-time use — lets a grower test the system before committing to a larger size

Who Should Use This Starter Kit

Growers trying House & Garden's Cocos system for the first time on a coco coir setup, and who want a complete grow cycle's worth of nutrient to evaluate it, will benefit from starting with this kit before scaling up to larger bottles.

About House & Garden

House & Garden is a nutrient and additive brand established in 1990 by William Van De Zwaan, whose family had a background in Dutch horticultural glasshouse production; the company formulates its base nutrients and additives in small batches, filtering its process water through multi-stage ceramic filtration. Hydrofarm acquired House & Garden in 2021, and the brand's manufacturing and research operations are based in Humboldt County, California, building a product line of base nutrient systems and root, flowering, and growth additives sold to growers in dozens of countries.

Frequently Asked Questions

What's included in this starter kit?

It includes one bottle each of Cocos Part A and Part B, the two components of House & Garden's coco-coir-specific base nutrient. Both parts are needed together to feed a full growth cycle.

How long does this kit last?

It's sized for a full grow cycle using 15 gallons of feed water weekly, covering a 2 week vegetative stage and an 8 week flowering stage. Actual usage will vary somewhat with reservoir size and feeding frequency.

How do I mix Part A and Part B?

Add equal amounts of Part A and Part B directly to your feed water, mixing thoroughly between additions. Never combine the two concentrates together before they reach the water, since mixing them at full strength can cause nutrient lockout.

Why does coco coir need a specific base nutrient?

Coco coir has a natural cation-exchange capacity, meaning it holds onto calcium and magnesium while releasing potassium and sodium in their place. Cocos is formulated to account for that exchange, which a base nutrient built for another growing medium typically won't do.

When should I upgrade from the starter kit to full-size bottles?

Once you've completed a grow cycle and confirmed Cocos works for your setup, moving to a larger bottle size cuts down on how often you need to reorder. House & Garden sells Part A and Part B separately in sizes up to 1000 L for growers scaling up.
