This one is a fast grower. out of all my plants it is the tallest. havent done anything special to it. for this week I switched out my 900w LED for my 600w ViparSpectra. Temps have gone down to around 70-80 degrees average. I also added a humidifier and I try keep it around 50-60. The plant seems to be growing well so far and i have had no complications. Ive only watered when the top of the soil is dry. I think I will finally switch the plant over to a 3 gallon pot starting on the third week Because i can see that the roots are poking out from the bottom of the solo cup.
