they are around 3 inches tall. they are in dirt and they had white roots coming out of the dirt. When I got them home I transplanted them into 5 gal buckets so I could place them in the grow room. I had the light at around 1 1/2 ft from the plants, but one leaf was curling up and turning brown yesterday (I cut that leaf off at the stem(shade leaf)). I then raised the lights to around 3 ft and for the past two days have been shutting the lights off and on from time to time. there was one that was in a cube but it died so I went and got another plant (in dirt) two days ago. I did not understand the guy when he told me to acclimatize the plants. I did not want to leave them in the grow room in just the cub dirt. was afraid if them drying out. So I planted them. I am so new to all of this.
