Description

The Choice for Large Areas – Fast Veg Growth – Excellent Flower Results

The Electric Sky ES300 is a 300 watt wideband grow light that uses the newest spectrum and light distribution technology.  The patent-pending GS1 wideband spectrum grows plants faster in veg and creates larger flower yields because it has an extended full spectrum through infrared.  Linear lenses send light in two directions, providing both downward intensity and side-to-side uniformity.

Electric Sky LEDs expand to fit almost any size grow area.  One unit creates a perfect rectangle of light.  Two units create a square.  Choose one or more lights for your system to cover the area you need.

Recommended configurations:

  • 1x ES300 – Flower 2’x4′ – 2.5’x5′ / Veg 3’x6′
  • 2x ES300 – Flower 4’x4′ – 5’x5′ / Veg 6’x6′
  • 3x ES300 – Flower 5’x5′ or 4’x6′ / Veg 7’x7′
  • 4x ES300 – Flower 4’x8′ – 5’x10′ / Veg 6’x12′

* Wideband spectra like the one found in the Electric Sky are more efficient for plant growth per photon than White LEDs, but it is less “electrically efficient” to create the spectrum.  Some studies suggest up to a 25% greater yield due to full activation of plant photosystems.

    Ten days into flowering and my plants look great! Fan leaves are a deep, dark green and not much stretch. My space is so much cooler as well. I am blown away by the ES300, plants look better than expected and with all the money I’m saving on energy and bulbs I won’t be going back to HPS/MH!

    I heard about the electric sky from a friend. Super stoked now that I wen’t though a full indoor crop with the es 300. My Plants produced big time. Done with bulbs, this is the way to go. Just the energy savings is enough to get my attention, but I did not expect this! Slowly switching my whole set up.

    I am so happy I made the choice to purchase the electric sky. From veg to flowering, I would say there is no comparison to anything I have ever tried in the past. I have been growing 15 years, and wish this came out when I first started. Life would have been much easier.

    I installed two ES300s in my 4×4 grow tent two weeks ago replacing a 600w MH lamp, making the change as I switched from veg to flower. The results are incredible: all my plants are already producing visible buds, which appeared after only a few days under the ES300s, and growth accelerated visibly, adding up to a couple inches a day (or even during the dark period!) The amount of plant matter has been accelerating as well. Light penetration under the canopy is excellent as well, there are no longer yellowing or dropping leaves even towards the bottom of the canopy. I do understand Dan’s caution that these lights are not for beginners: the plants may outgrow the space and will require more and careful pruning in future cycles to retain control and maximize production because of the fast growth – I’ve had to brush up on my pruning skills. Also, I’ve been able to reduce exhaust fan speed for tent ventilation because there is less radiated heat from these lamps, allowing the grow space to be at a higher temperature – which also means faster growth. But it can also mean higher humidity so watch out for that. Right now I’m running at 80 degrees and 45% humidity with my ventilation fan on the lowest setting and two circulation fans: one above the lamps to prevent stratification of heat near the top of the tent, and one near the floor to move the air through the canopy. I did not experience an overall reduction in heat production but that was because I chose a configuration that gave me more light than the MH for the same amount of watts into the tent, and the total watts is what determines heat production.
