Question 1

How much light do indoor plants need to thrive?

Accepted Answer

Some plants are different than others. We recommend you run your lights for 16 to 20-hours on vegetative crops. You can use an MH or CFL bulb for this purpose. If you’re flowering vegetables or fruits, you’ll need to drop the photoperiod to 12-hours on, and 12-hours off.

Question 2

How close can fluorescent bulbs come to my plants?

Accepted Answer

CFL bulbs won’t damage your plants. Even if the foliage ends up sitting on the lamp directly, you shouldn’t notice any burning or damage to the leaves or flowers of your plants. However, we recommend that you always keep the lights around 2 to 3-inches away from the top of the canopy.

Question 3

How often must I replace HID lighting like HPS and MH bulbs?

Accepted Answer

It depends on how often you use the light and the duration of the photoperiod you’re trying to emulate. As a good rule of thumb, we recommend replacing MH and HPS bulbs after each season for the best results.

Question 4

Is growing under LEDs worth it?

Accepted Answer

Many indoor gardeners swear by LED systems, while others steer clear of this tech. When selecting your LED grow light, make sure you look at the PAR, lumens, and the wattage of the light before finalizing your purchase.
