Actually you got some very good answers...
"...I know that just means more light penetration than a regular 20w..." Just so you know, that is not what that means. It means that the human eye sees the equivalent of a 70W incandescent bulb. For growing purposes, it really doesn't mean anything. Three bulbs are 60W putting out somewhere around 3500 lumens.
Like the others have mentioned, get rid of the glass bulbs. I would even consider removing from the self-watering planters. YOU want to be in control of how much water and nutrients they receive. Your soil looks rather barky and dense. Just because it is organic soil does not mean that it is good soil or that it does not need to be amended. I believe that you are going to din problems with the amount of bark and the density. Dense soil keeps the roots waterlogged. They also did not need to be transplanted in pots that large yet. It is harder to give the correct amount of water when tiny plants are in a large container. I believe that you are going to need to add perlite to your soil. I would also look for a source of soil that less bark and more dark rich soil. If your soil has nutrients, you will not need to add nutrients for a while. However when you do, all purpose plant food does not work well. For vegging you need something higher in N and K and low in P. During flowering you need something low in N and higher in P. If you don't know if a certain fertilizer is right, go online and look at the N-P-K of commercial nutrients formulated for cannabis. Organics and chemical nutrients do not co-exist. You are either organic or you are not. Chemical can and do kill the beneficials in organic soil.
How big a space are you planning on growing in? You are going to need a whole whole lot more light. When you get enough CFLs to be adequately lit, you are going to be generatring some real heat, which is going to have to be dealt with. It would be wonderful if we could grow dank bud with just 3 or 4 20W CFLs, but we can't. I know this is a learn how to grow experience, but without adequate lighting and ventilation, it really be a rather fruitless endeavor. WEhen you start adding up how many CFLs and howe many sockets and reflectors and cords you are going to need, I think you will see the cost savings of a HPS. CFLs are simply not cheaper. It is just easier to be underlit as you have multiple lights. You have to have enough light, regardless of the source.
