HLG 350 Diablo
Vendor:Horticulture Lighting Group
HLG 350 Diablo commercial lamps are designed to replace a 600 watt HID with just 330 Watts. Each HLG 350 Diablo uses 2 of our custom designed Advanced Design Diablo Quantum Boards® with Full Spectrum White & Deep Red LEDs.
With its rectangular footprint and integrated reflectors, this fixture is ideal for flowering in smaller grow spaces or vegging in a commercial grow. Integrated reflectors improve photon delivery resulting in higher quality yields even at the lower levels of the canopy. This incredibly efficient full spectrum horticulture lamp has an efficiency of 2.80 PPF/W.
An Access Point (sold separately) is required if you choose the GrowFlux wireless dimming option.

FAQs
How do you ensure your genetics are stable?
Every strain undergoes a rigorous stress-testing phase. We subject our keepers to light-cycle fluctuations and temperature swings to ensure they are 99.9% sexually stable before they ever reach our shop. We don’t just "chuck pollen"—we refine.
What should I expect for shipping and privacy?
Discretion is our priority. All orders are shipped in stealth, crush-proof packaging with no mention of "seeds" or "cannabis" on the exterior label. Most domestic orders arrive within 3–5 business days with full tracking provided.
Are these seeds legal to purchase?
Yes. Under the 2018 Farm Bill, cannabis seeds are classified as "Hemp" because they contain less than 0.3% THC. They are sold as collectible adult souvenirs. Please ensure you comply with your local state and regional laws regarding cultivation.
What is your germination policy?
We pride ourselves on a near 100% germination rate. While we cannot control your specific environment, we stand by our vigor. If you follow our Standard Germination Guide and encounter an issue with a pack, contact our support team with photos and we will ensure you are taken care of.
Do you offer "Bulk" or "Wholesale" for commercial facilities?
Absolutely. We work with licensed facilities globally. If you are looking for 500+ seeds for a commercial run, please make sure to reach out to us.
