FAQs
Can foliar sprays replace root feeding?
No. Foliar sprays are a supplement and a fast correction tool, not a substitute for a proper base nutrient regime. Use them to fix deficiencies quickly while you sort the root zone.
Do foliar sprays work during flowering?
Yes, with care. Most general leaf feeds should stop by early flower to avoid residue on buds, but ATAK by Optic Foliar is purpose-built as a flowering foliar finisher.
When should I apply a foliar spray?
Spray at lights-off or in low light so droplets don't magnify heat and burn leaves. Optic Foliar formulas are the exception — they're designed to be sprayed with lights on.
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.
