Excited to start my first grow! Soaked 4 seeds overnight in a glass of water then put in wet paper towel in the dark for a day or two. The front two seedlings have some good growth on them after a week, and the back two have sprouted but aren't doing much above ground yet.
I watched a video where a guy had 4 plants of different heights. He raised the pots of the 3 smaller plants, each by different amount, to create a level canopy. That might help you if your 4th plant is smaller.
good luck with it all, I'm a noob so cannot offer more than 3rd hand advice and best wishes.
