Right. Clear containers arent good because it exposes the roots and under soil to the light. Also 27 watt isnt going to do you through the entire grow. Is it a 27 watt equivalent or 27 watts of CFL? Either way, my CFL grow used four 80 watt CFL photography bulbs. Look up lumen outputs when you're looking for bulbs cause thats the important in terms of growth. Atleast 10,000 lumens is needed. Maybe invest is 8-10 23 watt CFLs
