I just have to comment
How do you plan on sexing the plants after 2 weeks?
4 plants in one pot...risky business
Have you ever seen a root system & how quick it develops?
What lights are you using?
You are saying not to comment on the plant/pot ratio but i dont think you realize how annoying/hard its going to be having to dig out & untangle the roots, not to mention all the stress its going to cause to your other plants
Would it not have just been easier to plant them all in small cups/pots for now?
