@Cotton46 , 300 watts for two plants is sufficient, remember this.. more light is always better, but only to a certain point, like with anything, it can be overdone..more light means faster and better growth but, they will also need more nutes to stay healthy.. my recommendation would be.. if you are gonna add the side lighting, do it with the next 3-4 harvests, this will give you time to make sure everything is dialed in.. its when you start thinking you can outsmart ma nature you will run into issues.. many, many factors go in to a successful grow, and we only have control over a few of them( factors), and many take care of themselves. as long as they stay looking healthy things are fine.. but the sooner a problem is noticed, the sooner it can be dealt with... we got yer back bro
