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

Product Information

Keeping houseplants alive can be a strenuous task. You need to place them in the proper location to make sure they get the right amount of light, and you have to water them correctly — because there is such a thing as overwatering your plants. Although water is, thankfully, easy to find in most places, proper lighting may not be. You might live in a place that doesn't face the sun, your home may not have a lot of windows or perhaps putting your plants in a certain place in your house doesn't fit your aesthetic. That's where indoor grow lights come in: You can use them to properly care for your plants no matter your lighting situation. This seedling grow light utilizes Samsung’s LM301H 3500K white spectrum, plus 470nm blue LEDs. Out of all the LED grow lights I’ve seen, the HLG 300L B-Spec is the most dedicated seedling and veg spectrum available. Recommended Distance From Plants: This doesn’t mean a full spectrum grow light can’t start seeds. A grow light that emits full spectrum light can start seeds, but only the blue portion of the spectrum will be absorbed by the seedlings. 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). 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.

If you’re maintaining a mother plant you’ll only need a blue spectrum, and you’ll need a light that’s emits a blue spectrum that’s intense enough for a full sized mother plant. Having a light dedicated for this purpose is a smart choice. High-intensity discharge (HID) lights: These lights are the most powerful lights for growing plants — perfect for grow spaces or larger plants. Typically, these are used in indoor farms or controlled-environment labs. The light they produce is both full spectrum and brighter than any other type of light. Though these lights are extremely powerful, with great power comes great cost. These are the most expensive lights for indoor plants and will require the most energy to run. On top of that, they produce a great amount of heat, so you'll definitely need a way to extract the heat or cool the space. You can see in the spectrum image above that there’s little or no red spectrum, so you won’t be able to use this grow light for flowering. If you need to light a large grow space for vegetative growth, consider the Scynce LED Raging Kale 2. This grow light has the same blue spectrum, but covers 6×5 feet for seedling growth, or 3×4 feet for vegetative growth. You want to find a grow light that emits light in the 4000 to 6000 Kelvin range. That range contains the most blue light.

This again depends partly on the size of mother plant you require and the space you have, you can keep micro mothers under T5 strip lights in small pots if you only require a few cuttings at a time. Or if you need large mothers CDM lights or metal halide bulbs up to 400w or even 600w, LED lights are very suitable for mother plants and you can get ones to match any size of mother you need. CFL bulbs and other fluorescents are ideal for most small to average mother plant requirements as long as you don’t need to be taking cuttings too regularly. 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! The vegetative phase of growth is critically important for your cannabis plant’s future yields. This is the phase where the plant develops its physical structure. There's a timer function, so you can choose to turn it on or off for four hours, eight hours or 12 hours. You can also dim the lights if you don't want them quite as bright. Since they're LED lights, you don't need to worry about excessive heat, so they can be decently close to your plants. Plus, they have excellent energy efficiency. There are 70 red LEDs and 10 white LEDs: The idea is to simulate sunlight at noon, when it's at its brightest and provides the most light. Since most of the lights are red, they're great for budding and flowering.

Take a look at the lights below that will provide sufficient intensity for maximum growth and development during this phase. The Best LED Veg Grow Lights: HLG 300L B-Spec In my post about Calculating The Grow Light Strength Needed To Grow Cannabis, I talk about the proper amount of light for starting cannabis seedlings, which is around between 200 to 300 PPFD. 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.Generally speaking, grow light manufacturers recommend hanging your grow light 24-30 inches above seedlings. This can be problematic because even though seeds don’t need strong light, the light intensity from a single bulb can be too weak to start seeds, which can result in stretchy plants. 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. 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. 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.

The increased sensitivity to light during these growth phases – which requires hanging your grow light higher than you would during flowering phase. This is why many of these seedling & vegetative phase grow lights emit lower PPFD readings. It’s because if you put too much PPFD on plants in these growth phases, you’ll risk burning them.Plants photosynthesise and grow when they are provided with PAR light (Photosynthetically Active Radiation). A second important factor when choosing the best LED grow light for starting seeds is the strength of the light. Many people choose to start seeds and vegetative growth with weak blue grow lights. The exact distance depends on the power of your grow light. A 300 to 400 watt grow light could hang 18-24 inches from the canopy. A stronger light would need to be dimmed or kept at a larger distance above the plants if running full power.
