Orange Sherbert Auto polyembryonic seedlings (twins)
Week G: Germination Stage
I started with two Orange Sherbet Auto seeds for this grow. One seed cracked and started growing as expected, but the other didn’t show any signs of life. I planted it anyway, thinking it might surprise me. After four days, I figured it hadn’t worked. But when I brushed the surface of the soil, I found two entangled seedlings—definitely not what I expected!
I carefully separated them and placed each in its own solo cup. I hadn’t seen this before, so I searched online and found out that these are polyembryonic seedlings. Basically, that means it’s a “twin cannabis seed.” Some seeds can produce two plants instead of one. One of the seedlings is usually stronger, while the other one might be a bit weaker. It’s rare, and sometimes the weaker seedling doesn’t survive, but I’m giving both a shot to see how they do.
For now, I’m going to watch how they develop. This is only my second grow in the cupboard, and eventually, I plan to take these two outdoors. I’ve got another diary tracking the progress of the other seed, which you can follow here: https://growdiaries.com/diaries/234999-orange-sherbet-auto-grow-journal-by-biglegs-cupboard
I’m using a locally made seedling mix that I bought from a grow shop online. I’ve used it before, and it’s always worked well—my seedlings seem to thrive in it. I haven’t started any nutrients yet, but I plan to use Big Plant Science nutes once the seedlings are ready for feeding.
Setup:
Medium: Locally made seedling mix from an online grow shop
Lights: DLI set to 12
Nutrients: Big Plant Science (not yet introduced at this stage)
The plan is to keep both seedlings growing and see what happens. I’m curious if the weaker one will catch up or if the stronger one will just take off on its own. Since these are polyembryonic seedlings, there’s a chance the weaker one won’t thrive, but it’s all part of the learning process. I’ll keep monitoring their progress and see how it goes from here.
This is all a bit of an experiment, but it’s also a great chance to learn. I’m still relatively new to growing, so I’m taking it one step at a time. If anyone else has dealt with polyembryonic seedlings or has any advice, feel free to share! I’m always open to learning from other growers.
Week 1: 24/09/24 – Slow Start
So, I’ve got the twins from that polyembryonic seed, and they’re off to a slow start. Keeping an eye on both of them as they figure things out.
One of the twins has a single, deformed leaf. At first, I thought it might be that mutation where you get long, elongated buds, but after checking here, it seems like just a funky leaf—nothing too wild. The other twin hasn’t done much beyond the seedling leaves (the first baby leaves they pop out with). No real leaves yet, but I’m giving it time.
This first week, I’m using Biobizz Fish Mix to keep them ticking along. I’ll introduce Big Plant Science nutes later, once they’re ready. I’ve got two lights, but for now, I’ve only turned on one. Using an Android app and a Bluetooth sensor, I’ve set the DLI to around 12, which is about 25%, which should give them what they need for now.
I’ll be keeping a close eye on them over the next week to see how they respond.
Current Setup:
Medium: Locally made seedling mix
Lights: One light on, DLI at 12 (set using Android app and Bluetooth sensor)
Nutrients: Biobizz Fish Mix for now; Big Plant Science later when they’re ready
Week 2: Moving the Twins Outside
After a slow start, I decided to move the twins outside and plant them together in a 5-gallon pot. Space is limited, and with how slowly they’ve been growing, they’re not getting their own pots this time.
I’ve had slow starters before, and they don’t usually yield much, so I’m keeping my expectations low. Since these two have been particularly slow, they’re sharing a single outdoor pot. The medium I used is a mix of 50% coco, 30% soil, and 20% perlite—this should provide good drainage and aeration.
I used Great White from Plant Revolution during the transplant. The taproots on both seedlings were barely visible, which made me nervous—especially with autos, since they can be sensitive to transplanting. But it had to be done.
Now, they’re settling into their new outdoor setup, and I’ll be watching closely to see how they respond.
Current Setup:
Medium: 50% coco, 30% soil, 20% perlite (now in a 5-gallon outdoor pot)
Transplant: Used Great White when transplanting
Taproots: Barely visible on both seedlings
Lights: Moved outdoors
Nutrients: Biobizz Fish Mix for now; Big Plant Science later if needed
Week 2: Vegetative Stage – Slow Growth, But Some Sunny Days
The twins are still growing slowly, which isn’t too surprising given their sluggish start. I’ve had a few sunny days, which has helped a bit, but overall, their progress is slow.
At this time of year, the weather here is a bit unpredictable. We’re getting some sunny spells, but it's still the rainy season, so the humidity is high. Daylight hours are around 12 hours a day, which is decent for the outdoors, but not exactly ideal for fast growth. I’m hoping the sunshine we’ve had will give them a bit of a push as they settle into their new setup.
They’re now in their 5-gallon pot with a mix of 50% coco, 30% soil, and 20% perlite. I’ve been using Biobizz Fish Mix, keeping it simple for now while I wait for signs of stronger growth.
Current Setup:
Medium: 50% coco, 30% soil, 20% perlite (in a 5-gallon outdoor pot)
Weather: High humidity, around 12 hours of daylight, with some sunny days
Nutrients: Biobizz Fish Mix for now; Big Plant Science later when they’re ready
Week 4: Vegetative Stage – Slow Growth Compared to Indoor Sister
The twins are still growing, but the pace is slow. There’s a massive difference compared to their indoor sister, who’s thriving by comparison. It’s clear that the outdoor environment, even with the sunny days, isn’t pushing these two along as quickly.
Their progress is steady but slow, which isn’t too surprising considering how they started. I’m continuing with Biobizz Fish Mix to keep them going, and the weather’s been decent, but it’s clear they’re not keeping up with their sister indoors.
I’m still keeping an eye on them, but I don’t have high expectations for these two. I’ll just let them do their thing and see how they shape up over the coming weeks.
Current Setup:
Medium: 50% coco, 30% soil, 20% perlite (in a 5-gallon outdoor pot)
Growth: Slow, especially compared to their indoor sister
Nutrients: Biobizz Fish Mix for now; Big Plant Science later when needed
Week 5: Signs of Flowering
The twins have finally started to show the first signs of flowering, which is a bit of a relief after such slow growth. Despite their sluggish start, they’re beginning to transition into flower. Compared to their indoor sister, they’re still far behind in terms of size and development, but at least they’re moving forward.
I’m sticking with Biobizz Fish Mix for now, though I’ll likely introduce Big Plant Science soon to support the flowering phase. They’re both still sharing the same 5-gallon pot outdoors, and the weather’s been decent enough, with some sunny spells helping things along.
It’ll be interesting to see how they develop from here, but I’m keeping expectations realistic given their slow start.
Current Setup:
Medium: 50% coco, 30% soil, 20% perlite (in a 5-gallon outdoor pot)
Growth: Slow, but showing first signs of flowering
Nutrients: A fair amount of rain, so haven't watered apart from a little runoff from watering my other plants
