Nutrient Starter Kits
Nutrient starter kits take the guesswork out of feeding — complete base-plus-additive bundles from trusted brands like Green Planet, BioMega and House & Garden, matched so your plants get everything they need from seedling to harvest.
Why Start with a Nutrient Starter Kit
Complete Feeding in One Box
Each kit pairs a brand's base nutrients with its core additives, so you follow one feed chart instead of piecing together a schedule bottle by bottle. Open the box, mix, feed.
Nutrient Starter Kits Our Customers Actually Buy
The Trichfecta+ set by BioMega and Green Planet's Dual Fuel Starter Kit are the two kits our customers reach for most — proven combinations for a first grow, not shelf-fillers.
Grower-Run Advice When You Need It
We've been growing for 14 years. If a feed chart doesn't make sense or you're not sure which kit suits your setup, ask — you'll get a real answer, not a script.
Ready to build your own mix? Step up to hydroponic nutrients, boost results with hydroponic additives, or go medium-specific with coco nutrients.
FAQs
Do nutrient starter kits include everything I need to feed my plants?
Yes — each kit combines base nutrients and additives from a single brand's feed program, covering your plants from seedling through to harvest.
Which nutrient starter kit is best for beginners?
The Trichfecta+ set by BioMega and the Dual Fuel Starter Kit by Green Planet are our most popular — both follow simple feed charts that suit a first grow.
Can I use a nutrient starter kit in coco?
Yes — the Coco Starter Kit by Hy-Gen is built specifically for coco, and other kits list their suitable media on the brand's feed chart.
Welcome to The Grow Guys
We built The Grow Guys from the soil up — well, coco and perlite. Before we sold gear, we bought it, ran it, and learned the hard way what's worth the money and what ends up in the shed. That's the filter everything on our shelves passes through. No sales scripts, no rebadged junk, no telling you what you want to hear. Just gear we'd run ourselves and advice from people who actually grow. Chasing higher yields, tighter flowers, or your first harvest? You're in the right place.
