ILGM Jack Herer Feminized
Vegged for 56 days (from sprout above ground)
Flipped to 12/12 lights 3/15/2023
So now it’s day 16 in flower
Although Jack Herer is mostly sativa, my plants have not stretched and are now still only about 20” tall.

I’m sure you mean 16 days since the flip. Those plants are just starting to flower in earnest. The stretch is yet to come.

Yes, 16 days since I flipped the lights to 12/12. I hope you’re right…that I’m panicking too soon!

Im sorry, in your first post you said 12/12, but in your breakdown, you said mechanical timer 18/6. My bad.

I may have goofed up! I realized three days ago that there was a power strip inside the tent with a bright orange led. Also, I was using a reptile heat lamp bulb in the tent.

Its all good. At least you caught it.
I hope so. I cover the power strip led with black duct tape. And I put to reptile heat lamp bulb under a clay flower pot. But I wonder if I’ve missed.the stretch and am doomed to short plants and a low yield.

Short plants don’t always equal low yield. Sometimes they’re just short and fat.

Same here. 29 days of 12/12, and very little stretch. I can’t explain it either. I have been dealing with a calcium issue I think though. Either to much, or to little, I don’t know which.

Mine look like that! Are yours Jack Herer, too?
It’s actually only a week in real flower @Isleofdogs. You can throw out the first week or so.

Yeah that first week they don’t do much. Week 2 they stretch a tiny bit more. Week three is when you’ll know if they are gonna stretch and sometimes they are not done till week 4 and I have some grow and inch in week 5. So much good advice here already! Just want to confirm also that those short ones are often the best and fattest nugs ever. My fav this run was the one that did not stretch at all.

OG kush is mine.
The one on the left might have some stretch left. The one on the right should be about done stretching. Might go a little more.
Doesn’t necessarily mean you are going to lose out on yield.
One other thing that will help the stretch is when you drop your lights to 12/12, did you lower your DLI? My last week of veg, I am at about 50-55 DLI and the day I switch, I drop back to 30 and increase it 5 DLI each week til I am back to 45-50. Week 6-7 of flower I drop back to 35 and increase again 5 DLI each week til harvest with my max DLI the last 3 weeks being only 45.
It’s a DLI roller coaster like the chart.
I dont see the actual stretch til the 3rd week of flower.
Had, I think, some light burn on previous grows. With this third grow, I’ve been using the Photone app on my iPhone (sun direct setting), a paper diffuser, and that very chart. Thanks!
