Cut all the big fan leaves off hoping to stunt them so they didn't grow 5 feet tall. After cutting all the fan leaves (I was told to bend them down) the shoots have gone nuts and now have full canopy of leaves and the bud sites are all now growing.
Using a 250 HPS the light wasn't penetrating any of the shoots. The big fan leaves covered them up.
They're still growing about a foot per week. It's near the end of the first week and 2 grew 11in and one that has always struggled started past 13" from 7" the two main ones are about 2 feet tall now.
Just wanted to share with my results.
Alternatively you could try pinching the tops of your plants to stop upward growth. Just go about 4-6" below the tops and slightly pinch the stem. This will cause the upward growth to slow while the plant heals. I don't mean snap the tops either. It takes a light touch but will save you from stretchy plants. Or use this pinch technique to keep your canopy even.
One day you might come across PGR. Using this type of chemical is an advanced technique to keep plants at the height you choose. I highly recommend you do research on PGR before using it if you go that route.
Do not go stripping fan leaves off your plant randomly. Leaves are your solar panels bro. Every pluck of a leaf should be done with care and purpose. Let me brake it down for you cause no one ever did this for me.
Exactly one week after you flip 12-12 you are to mani the bottom 1/3 of your plant. Strip away all leaf and smal shoots. You can also pluck any dead leaves in the canopy. If you see a main shoot that is questionable height leave it for another week or so. You should also be putting on your first set of nets at this point.
Weeks 1-3 you should be cleaning up the lower section of your plant as you see leaves droop and trimming off tiny shoots that will never get light in the lower canopy. As the plant grows you follow the trim keeping that 1/3 off the bottom.
Around week 4-6 you will selectively pick leaves off from the guts of your plants to insure proper airflow thru the canopy. Your second set of nets should be done at the beggining of week 4. You can go to week 5 but don't let those girls get away from you. Putting nets on to late will bust a lot of tops. That's bad.
Weeks 7-8 you will want to start lightly thinning out the canopy removing large fan leaves that are blocking nugs from light. This will get your premature nugs to harden and ripen up in your final days.
These steps will help increase your weight big time. One of the biggest secrets to high yields is how you manicure and prune your plants.
Good luck
