Scrog - fan leaf removal

21 posts in this topic

Good morning

 

im a long time viewer but haven’t really posted. I’m am doing my first scrog grow and 8 days into 12/12. The canopy is THICK.. lovely heads everywhere..

 

ive looked at lots of flowered scrogs and it appears at some point most or all of the fan leaves are removed. When do I do this, do I just do all in one go?

Defoliation makes sense as at the moment u can only see heads....

 

little bit about the grow

My 3rd grow of 4 different strains

all in dwc but this time I have linked the buckets for easy empty/fill.

im using general hydro nutes

1.2 by 1.2 tent in a cold location

400w and 600wHps (I know)

(I did build RDWC but it was too loud)

 

Strains are

Gzkittles

dark ghost train 

Blue Dream

Amnesia Lemon

 

Cheers 

Col

Sorry just to confirm I have removed all growth below the net/canopy - lollipopish..

 

I am talking about the fan leaves above the net..  ie where the bud will be

Are you trying shoots down to the net or using it to spread the upward shoots of a multi-topped plant?.

 

Only on my second grow but as my last got a little bit wild I decided to go in hard and fast with the lst and defoliation this time - I tie down to the net so have been taking off sun leaves as and when I feel they're shading out side shoots, which just happens to be most days at the moment, but plan to let my tops go vertical a week before flipping to 12/12 then trim out any unwanted sun leaves as they stretch up

I veg the plants to about 20cm then supercropped them over. Put the net over the top and just kept feeding the heads outward until the net was almost full. They are now 2 weeks into flower and I have a full canopy of tops.
 

the problem is there is minimal light getting beyond the canopy top and no room between plants for the fan leaves.

If you are 2 weeks into flower then would only do a VERY LIGHT defoliation of middle/upper fan leaves to allow a little more light down and better airflow ONLY if it's too overcrowded. If you can upload a photo, it would be better to tell if you're overcrowded or not. Different genetics are bushier than others so it's kinda hard to tell without seeing.

 

If it's not too overcrowded, would leave the fan leaves do their job. Don't do any unnecessary defoliation. Aim for better canopy management next run. It's possibly controversial but think fan leaves play a necessary role in plant health. Only remove as little as possible from the upper parts of the plants if necessary.

 

You can remove more leaves in the last week of flowering while flushing and leaves are dying, helps to make harvest easier in my opinion. Again don't go over kill.

Wait till they have stopped stretching. Then you will know for sure which need to come off if any. A plant will look totally different 3 weeks into flower than a plant a week into flower

 

Personally I take none off at the canopy seeing as they are the solar panels for your plant but thats me

Thanks guys.. 

 

previous grows I have been very strict about what grows - had 16 well separated colas per plant.  Taking everything off but that wasn’t part of the plan.

 

the scrog has been a bit unnatural to me, as I have kept defoliation to a minimum. I definitely have much larger plants than previous - I will get a couple of pics later...

I’m lst my plants there almost 7weeks in veg I’ve removed some fan leafs only like 3-4 on each plant as they were massive and covered up to much growth but I’m going to leave them to grow out for another week or two before I switch to 12/12 then maybe remove some bottom growth and other fan leafs after stretch is over depending on leaf removal during flower not sure if it’s a good thing or not but il look into it @Owderb << or this pro can tell me lol
