Botanicare
Now at Green Harvest
Botanicare
Engineered to grow. Botanicare started as one experimental nutrient brewed in the back room of a Tempe, Arizona grow shop — and became one of hydroponics’ foundational lines: the one-part Pure Blend Pro bases, the Cal-Mag Plus every RO grower knows by name, and supplements built to customize, correct and enhance any program. Green Harvest stocks the working core of the line.

Why Botanicare?
Botanicare’s origin story is a grow-shop story. In 1992 Treg Bradley opened a hydro shop in Tempe, Arizona, and started experimenting — brewing an organic plant supplement in the back room and handing it to his favorite customers to try. They came back for refills in droves. That experiment became Pure Blend, then the Pure Blend Pro line, and by 1996 Bradley had sold the stores to focus entirely on the formulas he’d launched as Botanicare. Twenty-plus years later the company still calls itself what it has always been: cultivation experts, dedicated to superior products, expert advice and support to help growers produce better crops.
Born in a grow shop
Pure Blend was brewed in the back room of a Tempe retail store and proven on that shop’s own customers before Botanicare existed — formulas tested at the counter, not just in a lab.
One-part simplicity
Pure Blend Pro is a complete one-part base program: Grow for veg, and two Bloom formulas — one tuned for hydro and soilless, one for soil. No A/B pairs to measure and balance.
Customize. Correct. Enhance.
Botanicare’s own framing for its supplements: Cal-Mag Plus corrects your water, Liquid Karma enhances every stage, Silica Blast fortifies the plant — tune any base program, theirs or another.
Root zone first
“A strong root zone is key to maximizing your yield” is Botanicare doctrine — Rhizo Blast packs on root mass while Vitamino carries plants through transplant and stress.

Featured
Pure Blend Pro Grow
The vegetative base of the Pure Blend Pro program — a complete one-part, natural-and-organic-based formula you run from transplant to flip, with no A/B bottles to balance.
Pure Blend Pro Bloom Hydro
The flowering half of Pure Blend Pro, tuned for hydro and soilless systems — recirculating, drain-to-waste, coco or rockwool.
Pure Blend Pro Bloom Soil
The soil-specific Bloom formula — blended for containers and beds, where the medium itself does part of the buffering work.
Cal-Mag Plus
The industry’s go-to calcium, magnesium and iron supplement — puts back what RO filtration strips out and what coco ties up. A permanent fixture in serious reservoirs.
Liquid Karma
Kelp and fulvic-based metabolic catalyst for every stage — vigor, nutrient uptake and stress recovery, run in the reservoir or sprayed as a foliar.
Silica Blast
Potassium silicate that stiffens stems and cell walls and helps plants ride out heat, drought and heavy feeding without folding.
Vitamino
B-vitamin tonic for the rough weeks — transplant shock, stress and recovery. Keeps plants growing when conditions aren’t perfect.
Rhizo Blast
Concentrated root booster that packs on root mass through veg and early flower — highly concentrated, so a little goes a very long way.
That’s the Botanicare working core at Green Harvest — the full shelf, every size we stock, is in the Botanicare collection. Run a Botanicare formula you don’t see here? Ask us at the counter and we’ll check availability before you make the trip.

Anthony’s take: Botanicare is one of the lines I learned on, and Pure Blend Pro is still what I hand a grower who wants a complete base without juggling A and B bottles — one bottle for veg, one for flower, done. Cal-Mag Plus is the most-grabbed correction bottle on our shelf for a reason: if you’re on RO water or growing in coco, it’s not optional, it’s maintenance.
