- If your item arrives damaged, defective, or incorrect, we’ll cover the return shipping cost — and you’ll receive a full 100% refund or replacement, including any original shipping costs.
- If you’re returning an item because you changed your mind, you’ll be responsible for return shipping, and a 25% restocking fee applies.

Product Description
The Grower's Choice ROI-FV is a purpose-built vegetative LED grow light for veg rooms, mother plants, and early growth stages. Drawing 350 watts and producing up to 1050 µmol/s under its GC-5K (5000K) vegetative spectrum, it develops tight internodes and strong root-to-shoot structure across a 4x4 ft veg footprint — without the red loading that stretches plants prematurely.
Key Features
- GC-5K vegetative spectrum (5000K, CRI ≥86) – blue-forward light for compact, structurally strong vegetative growth
- 350 W / up to 1050 µmol/s – full 4x4 ft vegetative coverage with efficient power use
- 0-10V dimming 10–100% – tune intensity for clones through late veg; Master Lighting Controller support for up to 100 fixtures per zone
- IP66 wet-rated, passively cooled – no moving parts, built for humid propagation and veg rooms
- Foldable 45 x 44 in frame – fast install and racking-friendly
