Let there be light

I am just a bit past the halfway mark of flowering for the Granddaddy Purple and it is time for it to get it's first defoliation during flower. There are several reasons why you want to defoliate your plants, but you also need to make sure that you don't go crazy and take too much.

The main reason I wanted to trim off some of the larger fan leaves across the top layer of the canopy is so that light can get to the bud sites that were being blocked. During this last phase of flower, I wanted to ensure that some of the lower sites got adequate light penetration.

The buds have so many smaller leaves sticking out from them to gather light, that I am not really worried about removing the older and much larger fan leaves. With that being said you want to make sure that you don't take too many of the leaves all at once because it can really stress the plant out. The last thing I would want after about three months of growing this plant is for it to turn into a hermaphrodite due to stress.

Another good reason to defoliate is to increase air flow in the tent. Air flow is crucial at this stage in the game because you do not want mold to grow on your buds from high humidity and stagnant air. I've got two fans blowing across the entire canopy right now and it really seems to be working to move the air around and keep the plant healthy.

I have also begun to increase the flowering nutrients each week as we move into the later stages of flower. One thing I have never done with growing is to increase the nutrients towards the end. I have always way overfed my plants to the point where it was very evident in the leaves that there was something wrong. But I have been careful with not overfeeding and to slowly increase how much I feed them. These next couple weeks will be interesting to see what I am able to do with this plant.

In about two weeks, I will do another round of defoliation as I prepare the plant for its final weeks of flower. The buds have a really good shape right now. I am really enjoying growing this photoperiod compared to my autoflowers I am used to. Photos take a bit longer, but in the end, I think it will produce a higher quality plant than what I am used to. I am going to have to get some of my favorite strains as photos and compare the results with what I have already done.

Thanks for taking the time to stop by and check out my post. This next couple weeks will be exciting, so be sure to follow along to see the results.

The cannabis looks lush and very healthy, my friend. You're the first person I've ever heard that it needs to defoliate. Sounds very interesting.

Thanks man. I think most plants benefit from defoliation because it gets rid of certain parts of the plant and has a lot of benefits to it, which allow it to use nutrients and light more effectively.

Goodness gracious look at how purple those leaves are! They look absolutely amazing, and I can't wait to see how much you get during harvest! Those tops are huge and look dense as hell!

Have you had to keep a lower temperature in the tent for this specific strain? Only reason I ask is I've heard that some specific strains, like northern lights and GDP, require a colder climate to turn the colors they do! Is this true, or just a myth?

Thanks man. I’ve tried to keep the temperature at about 68-70 degrees. I’ve grown some colorful strains before but never paid too much attention to keeping the temperature low. I want to try and get it colder in the room, but I don’t think my seedling would be too happy about it.

Ok cool! That seems like a pretty decent temperature, even for "cold hardy" plants, considering how hot it can get during outdoor grows! But that's good to know that you don't absolutely have to keep colder temps to get colorful strains! Yea, I can definitely understand that, I'm sure they don't take to the cold nearly as well as a more developed plant would.

I have a feminized Northern Lights cross strain from ISC that I want to try soon, which is supposed to get pretty colorful, but I was curious if temperature played that big of a roll in the color change or if it just depended on the plant itself lol.

But, I can't wait to see how plump those buds get in the coming weeks!

These are amazing! I have always wanted to grow my own but never had the chance. I am going to live through you and watch the process and learn something along the way. Looking forward to the next update and I am excited to see how these beauties turn out!

Thank you. Hopefully you get the chance to grow your own one day. It has been life changing for me to be able to have my own supply.

I can only imagine. Also, you are able to know where it came from and how it was grown.

What a wonderful gallery out here. Just curious to know which lights you use.
