I am probably going to do photos this round. Can I use a Dixie cup until I determine sex or do I need something bigger? I only did autos before and planted in final size pot
You’re going to need a bigger pot. Solo cups are usually good for the first 2ish weeks before becoming root bound. It can take a plant up to 6 to 8 weeks to show sex.
Thanks, any recommended sizes or do people just plant in final pot and cull the males?
I transplant photos 2 times to manage height.
Solo cup (2 weeks) to 10" pot (another 2 - 3 weeks) and then to 10 gallon pots. Others may do different things. This is what works fine for me.
