Our Happy Clients

I have known the core team members of the UPL for more than 10 years and they have been very professional in the design of the lamps and even more fortunate in their experience with crops, they have always given us free consulting services for our projects, which is pretty cool. It is no surprise to say that we have been able to earn $35,000 on a single plant by relying on their updates on products and lighting formula, so if you too want to find a professional manufacturer, they will be your chioce.

I’m a pretty picky person, but UPL made me very happy because throughout the communication process they often removed my doubts or did everything I could think of or not think of ahead of time. I am an importer and not very familiar with the product, but there was a series of easy-to-understand product knowledge that allowed me to quickly learn useful information, and they were willing to work with us to provide a nearly free “sample test program” so that my customers no need to invest too much in the testing period. They keep me informed of the production process and plans throughout the production process so that I can feel comfortable just waiting for the product to arrive at my warehouse. As an importer for nearly 20 years, I have a very busy day, and I hope that every supplier I work with has the same work ethic as UPL, so I will definitely have more time to vacation and do more meaningful things.

Frequently Asked Questions

About Product

μmol/J stands for micromole per Joule. It is a measurement to determine how efficient a light is at converting electrons into photons. This is the important to judge the light efficiency.

PAR is photosynthetic active radiation. PAR light is the wavelengths of light within the visible range of 400 to 700 nanometers (nm) which drive photosynthesis.

is the measurement of PAR delivered to a specific area. It is expressed as micromole-per-meter squared-per second (μmol/m2/s). This is the only measurement that informs us of the amount of light being delivered to a crop which enables photosynthesis.

1. The right color spectrum; 2. PAR output, a saturation of the canopy is essential; 3. The more air flowing between top colas and light the better; 4. Heat Dissipation.

FX and FC series grow lights will grow your sweeties from the seedling to the flowering phase. And FT series is for vertical farming which is a perfect chioce for high lighting demanding crops in germination period, say Marijuana.

It’s going to depend on how your plants are reacting to the amount of light being given to them…if you are seeing bad light/heat stress which you are, then back off the lights 6 inches and see how the plants react, keep adjusting until you find the perfect height.Yet you could also make reference in our product details.

About Plants

Staying in the veg or flower stage too long can affect the quality of your buds. If in the veg stage, your buds will not get dense, in the flowering stage your plant may die before harvest.

If your seed has germinated, but it won’t grow, it probably has less to do with the seed and more to do with the conditions.

The soil needs to breathe and it can’t with all that sand. Dial-in a good watering system not too much and not too little. Keep ph in balance.

-Increase Light  Intensity (and possibly add CO2)
-Manipulate How Plants Grow (freeway to produce more bud)
-Provide Correct Amount of Nutrients (sometimes less is more)
-Control Growing Environment (let the growing environment work for you)
-Harvest Plants Properly (most importantly, don’t harvest early!)
