Can you use metal halide for veg?
Metal Halide (MH) lamps typically emit a white colored light. Traditionally Metal Halide lamps have been used by indoor growers during the vegetative stage of plant growth. They are ideal for growing plants up to the flowering and fruit production stages because they mimic the spring/early summer seasonal sun.
Is HPS or MH better for veg?
MH grow lights (metal halide) are suited best for vegetative growth and HPS grow lights are superior for flowering.
What’s the difference between HPS and metal halide?
What is the Difference Between Metal Halide and High Pressure Sodium? Both Metal Halide and High Pressure Sodium bulbs are part of the HID family of bulbs. The primary visual difference between them is that metal halide light is white and the light emitted from a High Pressure Sodium bulb is amber orange.
Can I replace Metal Halide with high pressure sodium?
Both Metal Halide and High Pressure Sodium bulbs are part of the HID family of bulbs. These bulbs cannot be interchanged without changing their ballast, the regulating element in all light bulbs.
What’s the difference between HPS and MH?
Metal Halide (MH) lamps provide more of the blue spectrum, which is ideal for leafy crops, and/or plants that are in a vegetative stage. High Pressure Sodium (HPS) lamps provide more yellow/red spectrum, which is ideal for most plants that are actively fruiting and flowering.
Are LED grow lights as good as HPS?
LEDs are much the same. Though they’re generally more efficient than HPS (with some clocking 2.8 µmol/joule), some LEDs are less efficient than high-quality HPS fixtures, and they give you less light. All too often, the µmol/joule rating on HPS products states the lamp efficiency, not the actual product efficiency.
One defining characteristic of metal halide grow lights is that they give off more white and blue light when compared to HPS lights.
Can a metal halide cause plants to grow bigger?
When I asked Professor Bugbee if the increased blue spectrum in metal halides led to bigger plants in the early grow stages, his answer was straightforward: “There is no theoretical or empirical evidence to support that claim. The apparent MH effect is likely caused by the amount of light, rather than the color of light.”
Which is better, thy or metal halide bulbs?
Metal halide lights tend to be considered great full spectrum grow lights, and thy are great for the vegetative state, as they usually produce really lush and thick vegetation which is great for getting weed plants ready for the flowering stage. Something that is cool about metal halide bulbs is that they can often be customized and changed.
Which is better for flowering, MH or HPS?
Generally speaking, both of these types of light, MH and HPS, are good options to go with, but for the most part, due to a couple of different reasons, HPS are the better option for flowering. Simply put, HPS grow lights tend to produce larger plant yields and higher quality results as well.
