First grow ever!

@MotaMama, You wont really know until you get to around 3 weeks I'm afraid. When you switch the light cycle you will find out which sex she is. Some people will do something called presexing which is flipping the lights early waiting to see the sex and then reverting back to 18 6 if the plants are female. This is a good option but it will cause stress to your plant. So I would wait atleast another week. I hope it is a Lady but unfortuatly its a 50/50 chance just like real life I suppose :) Keep up the fantastic work and stay safe :)

@MotaMama, I would not worry about it until you get later down the line and switch the light cycle from 18 to 12 your sex should show after a few days :)

@TheUk420Show, Thanks so much! I was okay with not knowing the pheno just incase i messed up or something went wrong, i figured best to try on the unknown before i go possibly wasting good genetics! How tall is super tall? One is about 3.5" and the other is maybe around 3"

@myfirsttomatoes, Thank you!
