    These supplementary lights are awesome. They really do bulk up your yields. Follow the usage directions or burn your plants. They don¡¯t stay on all the time, you manually turn them on for short periods of time. Very very cool. Fits nicely with the G3000 & SE3000. Live them.

I have Spider Farmer SE 3000 and 3x3 grow tent. Would it be recommended for this setup? Additionally, regarding the package contents - does it include two units as shown in the picture, or is it just one? Giorgi asked on May 17, 2023

The Spider Farmer SE 3000 is an excellent choice for your 3×3 grow tent setup. Additionally, we recommend considering the G3000 and SF2000 PRO models as well for your 3'X3' grow tent.

Furthermore, the UVR package includes two units of the UV & IR supplemental light bar, as shown in the picture. This versatile light bar is compatible with almost all bar lights on the market and comes with a non-slip, flexible, and adjustable bracket, making installation effortless.

Can you use multiple sets on 1 light? For instance I have the 7000 bar light. Could I mount 2 sets on it equally spaced for max coverage vs just running 1 set? Would it be beneficial in doing so? Thanks Eric asked on April 12, 2023

Yes, you can use two sets of UV&IR bars. Doing so can provide benefits compared to using just one set, as it would increase the total amount of UV and IR light emitted, which can potentially enhance plant growth and development.

Is the light supposed to be on 2hr off 2hr during the light cycle? Or on the whole time when the light is on Charles d Bruno asked on March 17, 2023

Hello, here are some usage tips:

celia answered on March 17, 2023 store manager

Does the sun turn uv/ir off at times during the day? Isn't the whole goal to match the sun's light matrix?
