LEDs (light-emitting diodes) are the new generation of grow lights that emit specific wavelengths of light for better yields. They are easy to program to reflect the exact needs of plants. LEDs work better in small spaces than HIDs and fluorescents, offering much more power plant growth per watt. Before we delve into how to cultivate marijuana with LEDs, let’s have a look at the most common types of LED grow lights on the market.

LED Grow Lights

There are many different LED models available today. You can easily find one that fits your budget and meets your needs for cultivating Cannabis indoors. They vary by size, spectrum, wattage, type of growth stage, coverage area, and more. You’ll also want to consider how you will hang the lights over your garden. Some are suspended, while others have a hanging kit included. The list can go on, but here are some of our most commonly asked questions about LED grow lights for growing Cannabis indoors:

Q1: How many watts do I need?

A: You can get a rough estimate of how many watts your light will need if you know the size of your garden and how much light is required for each plant. However, keep in mind that it’s easy to provide too much or too little light. The only natural way to gauge the optimum intensity of LED grow lights for Cannabis is to use a Lux meter, which can be purchased on eBay or Amazon. We recommend using one that has the capability for “peak lux” to get a more exact reading.

Q2: How far should LED grow lights hang from my plants?

A: That depends on what you’re growing and how big it is. For young seedlings, you’ll want to keep them closer. Once they’ve grown bigger, move your LED grow light system further away from the plants. It’s impossible to give a general rule for this as every strain is different and develops differently.

Q3: How do I set up my LED grow lights?

A: This will depend on the model of LED grow light you have. Some models can be set to specific stages, including germination, growth, and flowering.

Depending on your growth cycle, you’ll also need to download a timer that will automatically turn your lights on and off. We recommend checking out some YouTube videos for advice from experienced growers with the same type of lights as you.

Q4: What is the payback period for LED grow lights?

A: The payback period depends on your energy costs and how much you initially spent on the equipment. A quality LED grow light kit can cost around $500 or more, depending on your need. You’ll also want to consider that these lights last 5 to 10 years, so it can be a very cost-effective method for increasing Cannabis Indica indoors in the long run.

How to make feminized seeds at home? (Part 3)

This is Part 3 of a 3 part series on Making feminized seeds at home. Follow along with Part 1 here and Part 2 here. 

If you try your luck by starting your project with unknown regular seeds, you must make sure that these plants are homozygous for the feminizing trait, or else your project will be doomed from the beginning!

Step 2: Breed, a female with one of the males that you have obtained in Step 1

This part is straightforward if you have managed to obtain a male plant. If you found them by chance or bought them from someone, their feminizing trait may not be homozygous. If you breed them together, the resulting offspring will be all regular (containing both male and female chromosomes).

Grow these plants under an 18/6 light cycle because this increases the chance of creating feminized seeds (the number can be higher than 50%, but it’s not guaranteed to work with every strain).

You will need to grow these plants under continuous light to create auto-flowering seeds. The reason for this is explained at the very bottom of the article.

Step 3: Grow/breed the resulting offspring from step 2!

Now comes the final step, where you will see if your efforts were worth it or not. If you started with regular seeds, you would need to keep growing the plants until they show their gender. If you got your hands on feminized seeds, this step is not required because all of these plants will produce feminized seeds (as long as they are homozygous)!

Now that you know how to create feminized cannabis seeds, it’s time to discuss a few things you should consider before starting your project.

The first thing is the selection of the desired trait because it’s possible to create feminized seeds with different genders from their regular counterparts. This can be achieved by selecting one out of several available parents that carry the female gene.

If I wanted to create feminized seeds from a plant with purple buds, I would need to make sure that one of my parents is homozygous for this trait. This means that if I had five different purple parents, I could select the best of them and use him as a pollen donor.

This option may sound complicated, but it can still be more beneficial than buying feminized seeds from a random breeder. A good example would be Big Buddha Seeds, which sells regular and feminized seeds of the same strain!

The second thing is to make sure that you purchase your male plants from reputable sources because they may carry undesirable traits such as hermaphroditism. If you used one of these plants for your project, the resulting offspring would be hermaphrodites.

The usual ratio in feminized seeds is five females to 1 male, but this can vary between breeders and strains. This also means that if you get 10% males, 90% will be females, still perfect numbers.

Step 4: Take clones from the resulting plants and grow them

This step is unnecessary, but it will increase your chances of a successful project. If you get lucky with some of the seeds, you can use these clones for another breeding project while using the rest to create feminized seeds!

If you’re wondering how to make clones out of regular plants, I could recommend using the cloning gel I reviewed in my other article.

The final thing that you should keep in mind is that many breeders sell feminized seeds that are not homozygous because it would cost them too much money. If this is the case, buying these seeds will not give you the desired result. You will need to try at least four different seeds to find a homozygous plant because this increases your chances of successful feminization.

The real chance of creating a masculine plant from a regular seed is about 10%, but it can be significantly higher when using a method like the one described above. This means that if you try four seeds, finding a male plant among them is 40%, which is still not enough.

The chance will be increased even further if you use feminized seeds, but it will vary between different breeds/strains! You can also increase your chances by using more than one pollen donor simultaneously, which is why I recommend getting your hands on some regular seeds as well. This way, you will also gain some valuable experience and knowledge about the different genders of the plants.
