Three Autos - Amnesia, Northern and Blue

This is my first ever grow, Built a grow room in the basement (another story) and planted half the seeds in the soil, the other half germinated in water. At this point there is no obvious difference in growth. I'll check yields. The soil is identical in all the pots and I prewatered them before planting the seeds. The temperature varies between 30C and 26C and the RH humidity is between 76 and 50% The lights are ceiling T5 units and giving a total of 144w between two plants. Lights are on all the time but it's perhaps a little too warm, so for the 2nd week they are on 18/6 All the plants are autoflowers from ILGM and named: Amnesia Haze; Misty and Dazy Northern lights: Frigg and Aroura Blueberry: Belle and Bonnie
