Age Old Grow 12-6-6 Liquid Fertilizer, 2.5 gal

Push Vegetative Growth Without Burning What You're Building, 2.5 gal

Plants in the vegetative stage need steady nitrogen to build the structure that carries them through flowering, but synthetic high-nitrogen feeds can spike fast, stress roots, and leave harsh salt buildup behind in the growing medium. Age Old Grow 12-6-6 supplies that nitrogen from a natural, odorless base with a 2-to-1 nitrogen-to-potassium ratio tuned for steady, vigorous growth rather than a quick spike-and-crash cycle.

Age Old Grow ships in a 2.5 gal container, matched to larger gardens or multi-room growers wanting fewer refills.

Key Features & Benefits

• Natural, odorless 12-6-6 formula — delivers high nitrogen from plant-based sources without the harsh smell or synthetic salts of conventional feeds.
• 2-to-1 nitrogen-to-potassium ratio — is tuned to encourage vigorous, steady vegetative growth and stronger overall plant vigor.
• Supports the transition into flowering — helps set plants up for a smoother shift once they move from vegetative growth into bloom.
• Works as a foliar feed or soil drench — fits whatever feeding method already suits your space, from spray bottles to reservoirs.
• Suited to indoor and outdoor gardens — performs consistently whether plants are growing under lights or in natural sunlight.

Who Should Use Age Old Grow

Growers feeding plants through the vegetative stage who want a natural, odorless nitrogen source that builds steady growth without the spike-and-crash behavior of synthetic fertilizers, whether running a few containers or a full room, with the 2.5 gal size matched to that scale.

About Age Old Nutrients Grow 12-6-6

Age Old Nutrients, also sold as Age Old Organics, has formulated natural-based plant fertilizers since 1984, blending traditional growing practices with ingredient science for greenhouses, container gardens, and commercial cultivation. Grow 12-6-6 is built to pair with Age Old Bloom as plants move from vegetative growth into flowering — feed with Grow through the vegetative stage, then transition to Bloom once flowering begins, sizing each to how much you're feeding.

Frequently Asked Questions

Can I use Age Old Grow as a foliar spray?

Yes, Grow is labeled for both foliar feeding and soil drench applications, so it can be diluted and sprayed directly on foliage or applied to the root zone. Many growers alternate between the two methods depending on the stage of growth and how the crop is responding.

When should I switch from Grow to Bloom?

Most growers feed with Grow through the vegetative stage and transition to Age Old Bloom as plants begin flowering, when phosphorus needs increase. Making the switch too early can shortchange the nitrogen-driven structural growth Grow is formulated to support.

How do I apply Age Old Grow indoors versus outdoors?

It's formulated for both indoor and outdoor use across a wide range of plants, applied as a foliar feed or soil drench either way. Outdoor growers typically apply it on the same schedule as an indoor room, adjusting only for local watering needs.

What's the nitrogen-to-potassium ratio in Age Old Grow?

Grow carries a 12-6-6 analysis with a 2-to-1 nitrogen-to-potassium ratio, tuned to support vigorous, steady growth through the vegetative stage. That ratio is what separates it from a bloom-stage formula like Age Old Bloom, which shifts the balance toward phosphorus.

Does Age Old Grow leave salt buildup in the growing medium?

No, it's formulated as a natural, odorless liquid fertilizer specifically to avoid the harsh salt buildup common with synthetic high-nitrogen feeds. That makes it a fit for growers managing salt accumulation in soil or soilless media over a full season.
