Premium 320 watt full spectrum LED grow light engineered for complete 2x4 tent coverage with waterproof LEDESTAR diodes, knob dimming control, and folding design for fast installation in any grow room.

Delivers unmatched uniform light distribution across 2' x 4' grow spaces with 320W of professional LEDESTAR diodes.

The Tarantula Tent Ultimate 2x4 delivers precisely mapped coverage across every square inch of your 2x4 footprint using premium LEDESTAR diodes arranged in a folding design that installs in minutes and positions light exactly where your canopy needs it.

You control intensity with a simple knob dimming or pair it with the Grand Master Controller for complete environmental automation. The IP66 waterproof rating means you can spray, feed, and manage humidity without damaging a 320-watt investment.

Run it 12 to 18 inches above the canopy and watch uniform growth from edge to edge, something cheaper bar lights and blurples never deliver. Backed by a 5 year warranty because quality components last. Stop settling for uneven canopies and wasted energy. This light was built specifically for 2x4 tent growers who demand results.

FAQs

How many watts do I need for my grow space?

The wattage depends on the size of your grow tent or room. A general guideline is 30-50 watts per square foot for high-light plants like cannabis. For example, a 2x2 ft area may need 100-200W, while a 4x4 ft area may require 400-600W for optimal coverage.

What is the difference between full-spectrum and red/blue LED grow lights?

Full-spectrum LED lights mimic natural sunlight, providing a balanced mix of blue (for vegetative growth) and red (for flowering and fruiting) light. Red/blue LED lights focus on specific wavelengths but may not support plants as effectively as full-spectrum lights.
