Common questionsFrequently asked questions

What size grow light do I need for my space?

Measure your grow area and match it to the light's coverage. For a 2x2 ft tent, a 100W light is sufficient. For larger areas, consider multiple lights or higher wattage models like 200W for 2x4 ft.

Are full spectrum lights better than red/blue?

Yes, full spectrum lights mimic natural sunlight and support all growth stages, from seedling to flowering. Red/blue lights are less efficient and may not provide balanced growth.

How close should I place my grow light to plants?

For LED lights, start at 18-24 inches for seedlings and lower to 12-18 inches for vegging. During flowering, 12-16 inches is common. Always check the manufacturer's recommendations.

Can I use a regular LED bulb as a grow light?

Regular LED bulbs lack the full spectrum needed for plant growth. While they can support low-light plants, specialized grow lights are more effective for healthy growth and flowering.

Buying guideHow to choose

Consider your grow space

Measure the area you want to cover. Small tents (2x2 ft) work with 100W lights, while larger tents (4x4 ft) may need 300W+ or multiple units. Strip lights are great for shelves.

Check the light spectrum

Full spectrum lights (3000K-5000K) are best for all stages. Some lights offer veg/bloom switches for tailored spectra. Avoid blurple lights if possible.

Look for dimmable and daisy chain features

Dimmable lights allow you to adjust intensity for different growth stages. Daisy chain capability lets you connect multiple lights to one outlet, simplifying setup.
