Hey folks. I’ve got some plants on the go in my tent and they are rapidly outgrowing their SOLO cups. I don’t think I want to make any seeds this go round (I might consider doing some selective pollination, but we’ll see) so I want to sex them ASAP. I only have one grow tent so cloning and sexing the clones isn’t an option. My only option is to flip to 12/12 and see what I get. I am thinking it would be best to transplant them all to slightly larger containers, wait another week or so and then flip them. Then, as soon as I can sex them and cull the plants I don’t want, transplant them into their final containers.
Is there a way to do this that won’t stress the plants as much?
best to let em grab the soil a little roots dont do much when plant is putting energy to flower I always inspect my roots after a grow try two out and see the difference
From cups to liters of medium to fill with roots under 12/12, better to declare them in the cups directly. Take care more about the hydric stress in low volume.
Here is a trick I’ve learned and done a couple of times. Once they have five or six nodes, give them two nights of 12/12, then switch back to 18/6. Within a week you should be able to see pre-flowers and can eliminate the males and veg out the females a bit longer.
Sorry I am a bit confused. Are you recommending going up to 1 liter containers to avoid hydric stress? Not sure what you mean by “better to declare them in the cups directly.”
I’ve done it twice now. I did the two nights 12/12 then a week later flipped them. All showed within DAYS of that. So it definitely works and didnt stress them at all. Honestly, I think I will always fo this from now on. A lot cheaper than the Phylos or Steep Hill plant sex tests (I passed both ).
The instructions are what I posted first. This was a trick I heard from SkunkmanSam on Hash Church.
The second post is what I ended up doing. I flipped only because I have height limitations. Some did start showing pre-flowers, as any sexually mature plant will do. Righ around the time they start alternating nodes…
No, sorry my english. I take your context in count and to sex them in the cups directly seem to be the most strategic move, considering your needs.
About the stress, an hydric stress in these cups is far more high than sexing them in the cups. It was to “relativist” your concern about stressing the plants.
A female plant will present pistals while still very early in the vegative state. In general a Male will not present the pear shaped nodes at the base of the stalk of your babies. An 18 and 6 light cycle should be maintained. Stressing your plants is a poor way of sexing them.
