CFL Grow Light Buyer’s Guide

So, now that you’ve taken a look at our top 7 picks were you able to select a perfect CFL Bulb for the indoor garden? Well, we know that it is not that easy.

Narrowing down on one option from a list of excellent choices can be quite challenging. Apart from the pros, cons, and prices of the items, there’s quite a few other things you’ve to consider before choosing one.

So, to help you, we have designed a comprehensive buyer’s guide for your convenience. Without further delay, let’s jump right in.

  1. Colour Spectrum

If you are using CFL bulbs as grow lights to help small saplings grow indoors, both full-spectrum and color bulbs can be quite useful during the growing phase. But we would recommend that if you are not on a budget, go for the full-spectrum options for the best results. But, yes, before you choose a multi-spectrum option, consider that they are a little more expensive.

It would be best to select a multi-spectrum option because it is that it is the closest replication to natural sunlight with a complete spectrum of light. However, we do agree that the debate on which one is better is ongoing and never-ending. We would suggest that you choose one that fits your requirements and budget.

  1. Area It Covers

Coverage area is quite crucial when it comes to growing lights, and you have to choose very wisely. The area these bulbs will cover will increase if you move the plants higher, but the intensity of light that your plant will receive will decrease in such a scenario.

However, on the other hand, if you move the light close to your plants, PAR will increase, and coverage will decrease.

To understand this the best, do read the specifications well before you decide on buying one. But be cautious. Sometimes the PAR value listed on the packaging by manufacturers is misleading. They only list PAR in the central area and not of the surrounding areas. We’d suggest that you go for a product that is sold by a trusted manufacturer in the market.

  1. Wattage and Lumen

Well, your consideration for wattage and lumen should be determined by the area that your indoor plantation covers, or very simply the number of plants that are in the garden.

Generally, it is a good idea to give 80W-100W per square foot of your growing area. However, even 50-70W is enough for every square foot of planting area if you have vegetable crops. But if you have plants that need more light, like cucumber, tomatoes, or peppers, it is better that you go for options that offer high lumens and is of higher wattage.

Put simply, for every 2-3 plants, you will need bulbs with 150 wattages or more.

Just make sure that when you choose the bulbs, you do not select wattages and lumens so high that the plants get burned. Provide sufficient quantity and good quality of lights to your plants, and they will flower the best.

  1. How Many Bulbs?

When it comes to how many bulbs are suitable, the rule of thumb is the more light, the better. If you are growing saplings, you can start with 100 watts per plant. But do keep in mind that some plants need less light. So, before you can decide how many bulbs are required, figure out how much light your plants actually need.

Take a look around, see if specific patches have underwhelming growth. If that’s the case, you can easily determine that they would need more sufficient lighting for lush green growth. If your plants are not getting coverage from all angles, they won’t grow properly.

Keep in mind that with the CFL grow bulbs, the idea is to mimic natural lights for your plants. So, just like sunlight, it should cover most of the plant angles. Consider this when you’re placing the bulbs.

Verdict

We understand that your plants crave sunlight to thrive in the best possible way. However, sometimes it is not possible to give them the perfect natural light because of weather changes, outdoor risks, and many other issues.

We hope that this guide has been helpful to you to choose the perfect CFL grow light for your plants. Additionally, we also hope that the buyer’s guide has assisted you in making an informed decision.

But before we sign off, we would like to talk about our favorites from the list. Emart 4332004402 is the best overall.
