Hello,
For your situation, what constitutes ‘outdoor’ plants (species), and how many do you plan to grow? Also, are you using the term ‘farm’ loosely, or are you actually planning a large operation vs. a small hobby or an overwintering project?
As for the article and the products, if you scroll all the way to the bottom, you’ll see the Amazon affiliate advertising notification, and that more or less answers the question about the products. The topic was ‘Grow Lights for Succulents’, but most of the products would be better suited to grow lettuce. All of those red/blue combinations are designed for maximum leaf production, and that’s not a succulent’s goal in life.
Reference: LED Spectrum Effects
So, it does boil down to your purpose and the types of plants you’re growing. Some of the items listed as full spectrum are a bit better (380nm to 800nm), but that is still not ‘natural sunlight’ as claimed. It’s simply a significant section of the wavelengths that plants respond to. Looking at some of the hardware and design, too, I see that you need to look very closely at the length of the power cords, the need for cooling (larger LED grids), etc. Some need mounting gear, and hopefully they’re including LED drivers for the larger items. Check the size–some of those are quite small and don’t cover a wide area. Look for timers and other setting options.
Although they hint that some LED models have replaceable parts, that is not common at all. Maybe some of the hardware is replaceable, but it’s not often that you’ll find an LED grow light that allows replacement of individual LEDs. It’s usually not as simple as replacing a T5 fluorescent bulb. In fact, if you scroll down to the “Buying Guide” section, the next photo shows a fluorescent bulb fixture over succulents, so again, I question the usefulness of that article.
