Everything your facility runs on. One source, clone to harvest.
The Stack is our owned, commercial-tested product line plus the wider catalog around it. Standardize inputs across every room, hold a known cost per gram, and reorder without chasing twelve suppliers.
The Proprietary Stack
Seven proprietary brands, each built and tested in commercial rooms, covering the inputs you reorder most. One ecosystem, one account, consistent batch to batch.
PowerSi
Highly bioavailable silica plus specialty additives. Tighter internodes, stronger stems, better stress tolerance and nutrient efficiency, veg through late flower.
Drip Hydro
Fully soluble, separated two-part formula for per-feed control. No dyes or sediment, predictable EC, built for commercial fertigation and automation.
Char Coir
Single-origin, lab-tested, precision-buffered coco. Uniform structure and low, predictable EC for high-frequency fertigation.
ION
Commercial LED and HID fixtures. Even PPFD and strong canopy penetration, high efficiency, single-tier or vertical, veg and flower.
The Harvest Company
Commercial trimming and post-harvest tools. Gentle handling to protect quality, less labor, easy to clean, reliable across rooms.
Dialed In
Under-canopy lighting and spectrum control: the Tri-Spec UCL light and the Tri-Chan controller for channel-specific spectrum and intensity.
MMI
Engineered benching and racking that maximizes canopy. Mobile, heavy-duty, cleanable, single-tier to multi-tier vertical across multi-room facilities.
Put the Stack on one account
Owned brands plus the 15,000+ products you already run, ordered and reordered from one place.
What the Stack covers, stage by stage
The owned line spans the full cycle, so the inputs that touch the plant can come from one source and stay consistent room to room.

01
Propagation
Clones and seedlings root into buffered media on a controlled early feed, where consistency matters most before plants ever hit a flower room.

02
Vegetative
Plants build structure under full-spectrum light on a steady nutrient program, with silica supporting stem strength as canopies fill in.

Flower
Top light and under-canopy light work the whole plant through bloom, on a flowering feed tuned for the media you are running.
