You could run lights on 12/12 from beginning, it won’t show you sex any faster. The plants have to mature before they will indicate sex regardless of light schedule. On 12/12 from start this takes +/- 6 weeks. Which would be about the same as running 18/6 for 4 weeks and then switching to 12/12.
Knowing that, I feel the best way to be productive is to wait until plants are about 4-5 weeks old and take a clone from each and place in a labeled cup of ph’d water. Then place all the clones somewhere else on 12/12 or similar flowering schedule. If you change water out every 5-7 days the clones should live plenty long enough to last a couple weeks to show sex. Generally speaking, males show a little earlier so you may get some faster results from them.
Damn bro, i tagged the right guy. Thank you! I knew you messed with this since I remember you space constrained.
It’s not the answer i was hoping for… damn. Well, looks like im gonna start some seeds and get something going. I don’t want to put things on hold. Im in autopots now so i really need to stay equal as far as starting new grows. Dang. Now i gotta think. I’ve already got 2" gg plants ill probably do exactly as you said, then, if i have a female, ill try to keep it alive to start a clone for next grow. I just hate to start a new grow with 1 pot empty… If i just throw it in as a 5th regular pot, it kinda defeats the autopots purpose. Plus i would grow coco with jack’s 321… including runoff, flushing, 2x per day watering etc… It would be hard to fit that in my 5x5…
Im rambling sorry
Anyway, as always, thank yoh for the thorough response and explanation. You rock @dbrn32
If you are starting indoors and then going outdoors, just start early and let them go the the six + weeks and look for pre-flowers (balls or w/pistils). If you have to cull any males, you still have time to fill in with feminized plants. I plan to soak two of each strain of my regular (M/F) photoperiod beans that I hope to grow this week. By the end of March I should know how many feminized photo beans I should start. We are allowed 12 plants for medical patients here. Friends always appreciate any extra females for us to stay legal. Better than them buying teen clones at the dispensary in my opinion!
That’s amazing! Didn’t know that was possible for a consumer. Not sure i want to know that $$ bad though
I’ve already started 4 seeds. I only have 4 pots set up. I want the xl spring pots… so i don’t really want to buy another hard pot right now. I’m going to try dbrn32 method in water and see where I end up. I can 5 ready to harvest and 5 under 5"… kinda sucks but i should be thankful. In Missouri it’s 6 ready to harvest and 6 in veg any size… i could work with that
I run all seedlings and clones at 18/6 from 1 to 2 months depending on how they developed, and if i have room to put them into the flower tent. Had a couple that spent and extended period in veg. If anything it seems like they may finish quicker then the last round that only vegged for around 5 or 6 weeks.
That being said it normally takes a month before a plant will show what sex it is. I keep mine in veg until i know for sure its a girl. Or atleast a really good cross dresser.
I think i may have over trained/pruned last grow. I think i left it in veg too long. It was my first indoor photos and my first grow in autopots. I also think i wasn’t supplying enough oxygen. I only have 1 tent 5x5
