An Ultimate Guide for 300w LED Grow Lights
When you are buying LED grow lights of specific light intensity like 300w, it becomes extremely difficult for you to find the right kind of grow lights for your cannabis farm indoors. You need to find the right spectrum, the kind of money it would cost and also the kind of longevity and durability these bring in.
So, when it comes to buying the right products, some quintessential features should be taken into consideration. For your ease of understanding, we have managed to sort out some of the most important factors that you need to look out for when buying grow lights.
1. Start with the Light Spectrum
Typically, when you have the LED grow light’s intensity fixed, which is 300w in this case, you want to then move ahead and focus on the light spectrum next. Especially for growing something as sensitive as cannabis, you need to ensure that you are actively focusing on buying the grow lights that cover the required light spectrum for the cannabis strain you are growing.
There are white-spectrum lights and then there are targeted spectrum grow lights. If your cannabis plants require a certain spectrum of light throughout, go for the targeted spectrum lights. Those are found to be more effective and help promote the growth of the strains seamlessly.
2. Focus on the Wattage Draw
Grow lights might have to stay switched on for an hour, if not the entire day sometimes. And, when you have so many LED lights lit throughout the day, the power consumption and wattage draw is going to be on the higher side. This is something you need to focus on without any second thoughts.
With the rapid advancements in technology, more and more brands are now coming out with options that support power efficiency so you don’t have to feel guilty about keeping the grow lights switched on for 12-18 hours a day.
3. Coverage Area
Another factor worth considering when buying LED grow lights is the coverage area it provides. Typically, we’d recommend starting with options that will cover 4×4 inches or lesser. However, the more your grow lights cover, the fewer number lights you’d need to install in your grow room.
Always predict the amount of space you have the plants spread out in. Once you have that figured out, it becomes easier for you to find out which kind of grow lights you need and also the number of systems you’d need to cover the entire space.
4. Focus on the Price
Grow lights, especially the LED grow lights don’t come for cheap. There are cheaper variants priced under $50, however, when you are growing good quality and expensive cannabis strains, you want to focus on the quality of the grow lights too. Typically, it is better if you look at the individual features, including the spectrum and intensity of the grow light before deciding which one you need and which ones you don’t.
Also, the price is a determinant of the brand you are buying it from. So, if you don’t want to be saddled with a cheaper quality brand that doesn’t come with the warranty, you need to focus and prioritize the quality of the product.
While we are on the subject of price and costing, let us not forget about the warranty too. LED grow lights, at least the branded and good-quality ones come with the right kind of warranty. If the product lacks a warranty, be assured that you will be struggling with the overall quality of the product.
Some brands offer warranties between 1-7 years. You want to ensure that you get the right warranty that lasts at least 3 years so in case there’s something wrong with the grow light, you can have it fixed without any kinds of issues or by paying any kind of extra money.
6. Heat Sink
Since grow lights are kept switched on for the majority of the day, being mindful of the thermal management process is also important. You want to ensure that the design has enough ventilation so that the lights don’t heat up beyond repair and end up combusting in the end.
Typically, they should come with a heat sink that will allow the heat to dissipate throughout the day and ensure they grow lights stay cool.
1. What should you consider before buying 300W grow lights?
When it comes to buying grow lights, it is extremely important that you keep a check on the quality of the product and LED lights. The first thing you need to consider is the intensity of the LED lights. This is something that you can’t do without. Aside from that, you also need to focus on the accessory features including the design of the grow lights, the safety features, and other features like waterproofing.
2. Are the cheaper 300W grow lights worth it?
The price of the grow lights isn’t the primary factor. You can often find grow lights that are affordable but work very well. It all depends on the quality of the product that you are buying. That is what matters in the end.
3. Is it better to get a full-spectrum grow light?
If you are buying grow lights for your indoor garden or hydroponic system, you must invest in the full-spectrum options that mimic the look of the sunlight. So, get ones that support varying blue, red, and white lights that can further promote the growth of the plants in different settings, including the vegetative stage and the flowering stage too.
4. What should the ideal coverage of my grow light be?
The answer to what is an ‘ideal’ coverage depends upon the grower and the number of plants they plan on growing. Those growing a large number of plants need a larger coverage while those growing a lesser number of plants need a smaller coverage. The easiest way to measure the kind of coverage you need is by checking the size of your grow tent. If you are growing in a 3×3 grow tent, you need to get a grow light which has a flowering coverage of 3×3. Always make sure that you’re looking at the flowering coverage while looking at the coverage of your grow light because it tends to be lesser than the vegetative coverage.
5. Where can I buy the best 300W LED grow lights?
You can get hold of some of the best 300W LED grow lights on the Amazon web store. We suggest buying on Amazon because you get great deals and discounts, as well as a really large variety of options there too, when compared to an offline store. If you intend on buying these lights offline, 300W lights are actually quite easily available across most gardening stores. However, Amazon, as we pointed out earlier offers a better variety and easier returns too. For your ease we have linked all our grow lights to Amazon so you can order from there in one click.
6. Should I buy 300W LED grow lights with fans or without fans?
You can go for either model. Fanless LED grow lights are more of a recent phenomena, and they work really well. We assume that in the next few years lights with fans might completely stop. If you are living in an area where temperatures are hot all around the year, we recommend you to go for lights that come with a fan. However, fanless lights are great for areas with moderate climates as they don’t usually heat up unless the external environment is too hot. You can find a mix of both of these types of LED lights in our list above.
With so many brands and varieties of LED grow lights available in the market, finding the best one can be a little confusing. So, finding the best and ideal options is crucial. Also, keep in mind that the 300W light options are one of the best ones around. Moreover, look through the individual reviews because that matters as well. You want to invest in the lights with a good pay-off.
