Which way to go? HPS Grow Light or LED Grow Light?

The question of LED vs HPS and which is “better” has been around since the LED grow light hit the market. While LED grow lights have certainly come a tremendous way since, can they compete, watt for watt, with the HPS grow light? And where do other types of HPS grow lights come into play?

 Advantages of LEDs over HPS

LED diodes are very electrically efficient, which could save you money over time (though the jury is still out when it comes to whether LEDs get better yields than HPS watt-for-watt). Additionally, where an HPS bulb needs to be replaced every few grows to maintain its brightness, individual LED diodes keep their brightness practically forever. With an LED grow light, it’s almost certain something else will break on the lamp before any diodes start losing their brightness.

  • LED grow lights last six times as long!
  • Eco-friendly LED grow lighting uses no toxic metals.
  • Energy savings range from 50%-70% over HID lights.
  • No cooling necessary; no plant burn and decreased risk of fires.
  • LED directional lighting requires no reflectors.
  • Maximum chlorophyll absorption and flower production.
  • Less frequent watering.
  • Discretion assured — no thermal footprint.
HPS Grow Lights


Advantages of HPS Grow Lights
  • HPS grow lights are capable of producing an intense amount of light, which can increase cannabis flowering.
  • There are a wide variety of HPS grow lights available, so options have become more standardized.
  • The initial start-up costs are lower with HPS grow lights than LED lights.
Drawbacks of HPS Grow Lights
  • HPS grow lights require more power and are less energy efficient than LED lights.
  • HPS grow lights have a shorter shelf life in comparison to LED lights.
  • The intense lighting of HPS makes adequate airflow and ventilation essential.
  • Setting the optimal temperature can be challenging, particularly in confined spaces.
  • HPS grow lights increase costs substantially in the long-term

2020 Best Quantum Board Reviews: Mars Hydro TS2000 vs Spider Farmer SF1000

Image
LED Quantum boards  are all the rage. It started with HLG, but now several budget brands have started offering quantum boards with Samsung chips and Meanwell drivers. Spider Farmer LED Grow Lights Energy Efficient These grow lights are more energy efficient than traditional LED grow lights. That’s partially due to the fact they don’t use cooling fans. Another reason is the LEDs they used in these designs are newer versions of diodes compared to grow lights that were designed years earlier but are still for sale today. Spider Farmer’s 2.7 micromoles per Joule is at the very high end of efficiency compared to most other grow lights that typically fall between 1.5 and 2.4 uMol/Joule. Features Uses 100 watts —  save about 50% on your electric bill over HID lights Equivalent to a 200 watt HID system —  but costs less to buy AND to operate Ideal spectrum for plants —  3000K and 5000K white light, plus 660 nm red and 760 nm IR; the perfect light for all stages of growth

How much rosin can you get from an ounce? 2020 Updated

Image
If you’re considering reaping the returns of a rosin press, the math isn’t too hard. But how much money can you make pressing rosin? It depends on a few factors. If you’re a commercial grower though, the answer is a good one: “more money than you’re making right now.” Even sweeter, getting started can cost as little as a few pounds of flower. Rosin is a cannabis oil extract that utilises pressure and heat, instead of a solvent, in its creation. The result is a completely pure, easy to make, and fast to produce cannabis concentrate. The beauty of rosin is that anyone can safely make it irrespective of experience. All you need is some bud, a flat hair iron (hair straighteners), and some parchment paper. So if you like concentrates, there is no reason to not give it a go! How Much Rosin Will I Get? Let’s use the metric system to get a more precise answer. An ounce of cannabis weighs around 28g so you could expect to get between: “2.8g – 5.6g of rosin per ounce of cannabis” It’s

Looking for the best quantum board? The quantum board LED is the latest advancement in LED grow light technology. In fact, as these new lights hit the market, we are seeing some fantastic quantum board led review feedback from users that suggests this might be the next level of LED available. Let’s take a look at what makes a quantum board special and why it might be the next big thing for your horticultural indoor farming. What is a Quantum Board LED? A quantum board LED is a newer alternative to the more expensive COB grow lights . The quantum board is a large circuit board in which a string of LEDs are connected forming “intelligent spectrum string” resulting in a broader spectrum and bigger plants. True full spectrum is the result. The Benefits of Quantum Board Led Grow Lights Chip on a board LEDs reduce the loss of power through circuit boards sending power to each LED in a grow light array. Quantum boards are even more energy efficient. This dramatically reduces their power consu
