SCROG Week 1 of Flower:  Lollipopping & final Topping

What’s up cannabis growers, My name is Dylan and welcome back to the Screen of Green Grow Series by GreenBox Grown.  This is the beginning of week 9 which means we are officially in Flower now.  In this video I will cover the changes you will need to make to your grow set up for the flower phase and I will explain the ideal environmental conditions.  At this point in time I will continue with training branches through the SCROG and I will let you know when this will no longer need to be done.  Finally, I will be covering the watering schedule for the week and I will also be Lollipopping the lower parts of all four of my blue dream plants.  I will explain more on what that means later on in the video.  Remember to visit the videos section at to jump ahead in this grow series, and now lets get started with day 1 of week 9.

In this shot I want to explain the changes you’ll want to make in order to start flowering your cannabis plants.  If you are growing auto flower plants, you do not need to change the lighting schedule but you will want to make all other changes I recommend.  For regular plants, the first step you’ll want to take is changing the amount of light they get each day.  For veg they get 18+ hours each day and for flower you will want to give them 12 hours of light and 12 hours of complete darkness.  Any light interruptions during the dark period can cause issues and lower yields.  The cool thing about regular seeds is you can keep them in veg for as long as you want and then switch the lighting schedule to force them into flower.  

Alright, so now that we are in flower, we will be using the flower nutrient mixes and for the first few weeks I will be still using the foliar spray as it is ok during pre flower.  You’ll see I have this tarp over my greenhouse and that is what I use for blacking it out at night to make sure no light gets in once the lights go off  .  You’ll want to keep temperature right at 75 degrees F still but you’ll want to lower humidity into the 40-45% range.  Once you have made all these changes to your grow room you are officially in flower!

This shot is to give you all a good look at the tops poking through the Screen and how it is really starting to fill out.  From this lower view you can see there aren’t really any that are tall enough to be trained so I will leave them be for the moment.

Today I will be lollipopping all four of my cannabis plants, and what lollipopping refers to is trimming all foliage away from the lower third of the cannabis plant so all that is left are the main branches that made it through the scrog as well as the foliage up top.  To do this all you need is a clean pair of trimmers and you are good to go.  You want to first determine which branches you will take down and my rule of thumb is anything more than 5 inches away from growing through the SCROG gets the chop.  Now i will start and remember to take away all foliage from the branches you are keeping and only do it for the bottom third of the plant.

Here I am right after finishing the lollipopping and you can see what is left and what I took down.  Be sure to get all the foliage out of the grow room and thrown away as you don’t want it decomposing in the grow space.  You can see up top I left everything alone, and that is because we want all the bud growth and energy to be focused above the SCROG where all the light is.  This will create larger yields and denser, tighter buds!

Now I will be flushing these plants with the siege hammer flush from fox farm.  This is what is recommended on the feeding schedule right before the first week of flower nutrients, and I will be mixing 2 tsp per gallon of water.  Be sure to really soak your plants and to get 15% runoff so you really flush them out!  Don’t forget to pH your mix and I also add coco wet as I am in a coco coir mix.

Next day and I want to give you a look at the plants and how they are growing since the lollipopping.  They don’t seem to be exhibiting any signs of s tress or shock and are still growing just fine.  It is also good to trim below like this because it allows for much more airflow between the plants, and that helps prevent mold and other issues from forming.  

Now the plants are ready for another feeding so I will be giving them the week 5 nutrients mix, which is the first mix of flower on the fox farm dirty dozen schedule.  I’ll be adding 1/2 a tsp of coco wet, and 1 tsp of cal mag per gallon of water as well and then after mixing everything together I pH it.  At this point I am using a full gallon and a half for these plants and am getting some runoff out of the bottom.  I am also still misting both above and under the SCROG so I can get a really good coat all around.

This is day 6 of the week and I want to show you how the plants are starting to exhibit signs of flower.  First of all, you can see all the tops are starting to turn a light yellowish color right at the  centers.  Also, if you get up close like so, you can see they are starting to produce the first couple of pistils that will eventually grow into large buds!  

For the very last day of week 9 I will just be providing a plain pHd watering and spray for the plants.  remember to give a good soaking for each plant, especially now that we are in flower.  If you under water during this stage, it will lead to smaller buds.

That concludes week 9 of the Screen of Green Series by GreenBox Grown which is also the first week of flower for the grow.  Next week, I will show you the early stages of buds forming on my plant sand will explain how to look at the trichomes and tell when they are ready for harvest.  If you enjoyed the video, please give it a thumbs up and feel free to comment below with your feedback.  Also, don’t forget to subscribe to the GreenBox Grown Channel and to turn on notifications for updates on my latest grows!  As always, thank you for watching and until next time…
