Types Of Grow Lights

There are a variety of different types of lights out there. They all have their own slight differences in how they affect the plant in the end. Let’s look a little bit closer at what these lights do and what makes them special.

Fluorescent Grow Lights

These are often used for the cheapest grow lights out there. They don’t provide the full spectrum of light making you in the end have a smaller yield of tomatoes. It seems like the amount of quality light the plant receives is correlated to the number of tomatoes you can harvest.

LED (Light-Emitting Diode)

LED lights are really the best. They are energy efficient and will also help provide you with the full length of lights. This makes you able to get a better harvest from your tomato plant. In the end, it’s really worth investing in this type of light. They cost a little bit extra but are well worth it.

The HID lights are perhaps the most difficult variety on this list to start setting up. They require more effort to set up and get the most out of. But they also help provide a really intense and strong light source for your tomato plants.

What To Look For When Getting Grow Lights For Tomatoes

As you have learned now there are a lot of different types of lights that you can choose from. But to keep it simple, then you should probably go for the LED or the HID types of light. They carry a price tag with them but also come with a higher quality of light. 

With these, you have a better chance of getting a good amount of yield and harvest on whatever you might be growing. For us, these are the only real options and we have never been disappointed in buying and using them.

Will Tomatoes Ripen Under Grow Lights

Tomatoes can definitely ripen under grow lights. Even though it might be a little bit different from natural sunlight. Often tomatoes grown indoors under these lights are ripening earlier than the ones outdoors. This is because the plant has greater access to light than the outdoors.

But the intensity of flavor might be slightly less. Sunripe tomatoes are really hard to beat in all honesty. They are sweeter and richer because of a longer amount of ripening.
