well i added a 42 watt cfl last night rated at 2900 lumens, i assigned it over my largest plant, i noticed a lil heat stress from bein 1/2 inch under it cuz all the leaves were clustered together this mornin when i checked on um, this means heat stress right, i think its just adjusting to the new stronger lighting source so now its 1 inch away, ive stopped using miracle grow today... im on my way to buy another 42 watt cfl or the largest i see... i know my plants are 41 days old, but in the beggining i had this one plant that was the tinest with the most fan leaves, it was light neglected i added more light and added some soil around the stem so it stands about two inchs above the soil with its like 6th set of fan leavesn and is thickening it looks female and its doing great, ince theres no problem witht his plant because it was just stunted for 2 weeks is there still chance if i add more light, i hope this additional 42 watt wil add another 2900 lumens to my growing room, but i dont think u can add lumens but if u could its be 5800 lumens which is great, but i gotta work, so ill be beack on tonight leave me comments and suggestions please thank you.
