Customer Questions

How far away should the light fixture be from seedling and vegetative plants?

18-30 inches. When they start to flower or bloom, lower 6-18in. These are recommendations and the flower will "speak" to the end user on how much light it will need and spacing as we don’t know the environment these are in, like how big the plant is, the soil they are using, water, pot, etc.

What color for winter succulents

Can you advise if you just have the seeds or have the succulents bloomed? That will make a difference on the color used. See below for recommendations. Blue and White are seedling and vegetative stages so you can do anywhere between 18-30in above. When they start to flower or bloom, lower 6-18in. These are recommendations and the flower will "speak" to the end user on how much light it will need and spacing as we don’t know the environment these are in, like how big the plant is, the soil they are using, water, pot, etc.

Will this fit in a 4x4 grow tent?

Product Dimensions - Inches (LxWxH) 46x5x2

I just purchased this light from Lowes. Instructions says to move switch to OFF and then select color. When I move the switch to OFF the light will not turn off. It does have the colors I selected but I am asking why it will not turn off with the switch.

The "off" on the time does not turn the lights off, it just turns the timer off.

At what distance from the light was the 215 PAR measured?

30” height.

Do all three lights have to be on to achieve the 215 PAR?

Yes, all 3 lights need to be on to achieve the PAR value.

if you direct multiple lights at one focal point will the PAR value double/triple depending on the number of lights?

If you have 3 lights and they all are over top of the same plant, then you would have triple the amount of PAR. It would depend on how many lights and the PAR for each, but you would multiple the value of the individual light by how many lights you have.

Do you have guidance on what colors to use at what stage. I see an example on the box but would like more guidance.

Blue light for seedling stage. White light for vegetative stage. Red light for flowers and fruit stage.

Can you provide a lumens rating with all 3 lights on at 18 inches?

PAR 214.67

What’s the PPF Output of this fixture?

PAR 104.6

If I want to germinate flower seeds which require light and either don't want soil to cover the seed or 1/8 inch of soil, do I use the red light? Also how far from the soil do I place the light?

These are only general recommendations. You may need to do more research depending on your specific project. Seedlings: blue light/24-30 inch/16/20h timer. Vegetation: white light/18-24 inch/16-20h timer. Floweeing: red light/6-18 inch/12h timer.
