Mother PlantSpectrum32 I Professional Grow Light 32Watt | for All Plants & Growth Stages

Product Information

Growers may decide to buy a dedicated grow light for the seedling and vegetative phases if their current grow light doesn’t emit enough blue spectrum – the spectrum that’s critical to the vegetative phase.

Watts or wattage (W) - the amount of power which a piece of electrical equipment uses. LED bulbs are more energy efficient with a lower wattage, and will last longer than incandescent bulbs with higher wattage. Bulb shapes and sizes: Not all bulbs are the same. They won't all fit in the same lamp. Make sure to verify the size of a bulb before purchasing it to ensure you have an appropriate fixture to add it to. This isn't just for bulbs either. Some lights can be up to two to three feet long, and if you don't have the space for a light like that, we wouldn't recommend purchasing one. From looking at the spectrum chart you can see it has a high amount of blue, yellow, green, orange, and not much red. This light spectrum was specifically designed for vegetative growth. This bulb from GE is ideal if you're trying to grow plants that flower or bear fruit. GE says this is a full-spectrum light, but its tint is more reddish than white, which would be better for budding and flowering plants. Because the bulb is an LED floodlight, it won't generate much heat, and the light will last longer than a traditional bulb. You'll also save a decent amount of money using this LED light versus a non-LED light. According to GE, this light has an output photosynthetic photon flux (PPF) of 15 micromoles per second, which is essentially the number of light particles the bulb is producing that actively help with photosynthesis. The higher the PPF, the better it is for the plant.Similar to starting seeds, the type of grow light you need for vegetative growth or mother plants is a grow light that only emits blue spectrum light. Blue spectrum light is in the 4000 to 6000 Kelvin range of the spectrum. Fluorescent lights: Another popular option people use to grow plants indoors is fluorescent lighting. These lights are affordable, decently energy efficient (though not as much as LEDs) and can provide a great spectrum of light to help promote plant growth. The main issue that can come with fluorescent lights is that their output can produce excess heat, which can cause problems. To deal with that extra heat, it can help to use a fan to pull out extra heat and expel it. If that sounds a bit too labor-intensive, consider buying a different type of light so you don't have to deal with this issue. If you have a strong grow light above 500 watts of power, you’ll likely need to keep a larger distance between the light and your plants – a rough estimate would be 36 to 48 inches if the grow light were running at full power. Every grow light has a different amount of power, so I advise reading my grow light hang height article. Follow the steps for yourself to determine exactly how strong your grow light is, and how high you should hang it. Ezorkas's LED tri-head grow light has 120 LEDs: 80 red and 40 blue. This is the optimum color range to promote successful plant growth, as both of those hues are perfect for optimizing photosynthesis and survivability. The colors can be used either at the same time or individually, depending on the stage of the plant. To power it, a USB plug is included, as is an AC adapter.

If you were to dim the grow light, that would reduce the distance needed between seedlings and the light. What Distance From Grow Lights For Vegetative Growth? In reality it’s not the distance from the plants that matters. It’s the intensity of light measured at the leaves ( read more about light intensity here).

The HLG 300L B-Spec may look small, perhaps for a 2×4 foot grow area. But the LEDs on the HLG 300L B-Spec are actually strong enough to grow seedlings and mother plants in a 4×4 foot area. The ideal environment for keeping a mother plant in is the same as you would have for vegetative growth a temperature range of 18-27Cis fine with the difference between the high and low temps being no more than 5C ideally (eg 25-28C lights on 20-23C lights off). Humidity is important to keep an eye on as if using CDM or halide bulbs or indeed sodiums the humidity will be much lower than under LED or flourescent lighting. It needs to be 60-70%RH ideally and to keep these high levels a small humidifier such as a Mist Maker 3 or Ram ultrasonic humidifier will keep your humidity high and your mother beautiful! Mother plants are generally kept for a long time some growers refresh them every 6 months or yearly with a cutting from the same plant that becomes the next mother, others keep the same mother plant for much longer. For this reason the most popular media for keeping a mother in is a good quality potting soil, its forgiving nature lends well to it being lower maintenance and is more suitable than coco or hydro for keeping plants long term. A great Soil for this is Biobizz All-mix, or Ecothrive super soil. Your pot size for a mother plant depends on the size of mother you want to keep which depends on the amount of cuttings you want to take at once but generally speaking a 10-20l final pot size is ideal for this.

Kelvin - Light bulbs will often be rated with a K number, this is the measure of the colour of light. Lower K numbers are warmer more red coloured lights (good for stimulating flower growth), higher K numbers are cooler more blue coloured lights. For good foliage and root growth a cooler colour light with a kelvin rate of around 6500k is optimum. Types of plants: Whether you're growing plants indoors or outdoors, not all plants can be treated equally. Some need more intense light, some need less light, some need different colors, etc. Before purchasing lights, you should research the plant you want to buy to make sure you can properly care for it before you take it home with you.

This 400 watt iPower metal halide grow light kit will give you the power and the blue vegetative spectrum you need at an affordable price. It even includes a separate HPS bulb to use during flowering if you want. HLG Recommends you hang this grow light between 24 and 32 inches above your plants. If you’re using this grow light to start seeds, you want to hang it on the higher side near 32 inches. If you’re using the 300L in the vegetative growth phase, you should hang it closer to 24 inches.

In addition, you’ll need several of those units to cover the 4×4 foot space you get from the HLG 300L B-Spec.

If you’re looking to grow the best harvest possible, in addition to other factors, I strongly suggest considering a dedicated veg light. If you’re looking for a grow light for your mother plant, you’ll only need one with a blue spectrum, in which case a dedicated blue spectrum light would also be appropriate. Why do growers want grow lights specifically for the seedling and vegetative phase (veg)?The B-Spec version of the HLG 300L model pictured above has a spectrum and LEDs specially geared towards plant growth in the vegetative phase. In other words this is a full blue/white spectrum grow light for seedlings and mother plants. So the logical solution is to determine the grow light height where your plants receive the ideal amount of light intensity for the respective phase of growth: 200-250 micromoles for seedlings and 300 to 400 micromoles of PPFD for vegetative phase plants.
