Commercial & Bulk Purchasing
We support operations & licensed facilities with volume pricing, dedicated account managers, and custom equipment consultation.
Who This Is For
- You are upgrading from a smaller fixture because you need to cover a full 122 centimetre tent without dark corners.
- You are switching to passive cooling because loud internal fans make maintaining a quiet environment impossible.
What We Found
- The reflector edges are surprisingly sharp, so watch your hands during installation in tight tent corners.
- This unit runs warmer than other 300W LEDs, so we suggest keeping your exhaust fan on a slightly higher setting.
What Users Say
- Growers switching from older blurple lights say they finally stopped guessing about plant health under natural white.
- Users running setups in spare bedrooms report they can finally sleep without the constant hum of internal light fans.
Mars Hydro TSW 2000 Full Spectrum LED Grow Light
Finding a balance between affordability and high-performance lighting is a common challenge for indoor growers. The Mars Hydro TSW 2000 solves this dilemma by offering professional-grade SMD LED technology at an accessible price point, ensuring your plants receive the intense light they need without breaking your budget.
This light is a significant upgrade from the smaller Mars Hydro TS 1000, providing a larger footprint and more power for serious home gardens. With a full spectrum that closely mimics natural sunlight, the TSW 2000 supports your plants from the early seedling stage through to the final bloom, maximizing resin production and overall potency.
As a core part of the Mars Hydro lineup, the TSW 2000 features a unique reflector design that increases light intensity while managing heat passively. For those with different space requirements, consider the elongated Mars Hydro TSL 2000 or the even more powerful Mars Hydro TS 3000 for expanded coverage areas.

FAQs
Measure your floor space to find the square footage. For decent results, aim for 30-50 actual watts of power per square foot of grow space.
Using multiple lights allows you to distribute intense light more evenly across the grow space, preventing hot spots in the center and weak light at the edges.
Seedling: 30" | Germination: 24"-30" | Veg: 18"-24" | Flower: 12"-18".
For the vegetative stage, use 18/6 or 20/4 (on/off). For the flowering stage, switch to a 12/12 (on/off) cycle.
The light is not waterproof. Avoid using it in environments where it may be exposed to direct water or excessive moisture.
