Right now I have two T8 40W bulbs over my 55 gallon. I currently have some hornwort, java fern, and amazon sword in the tank and I think that I should up the total wattage to 110W over my tank for long term success. Is there an easy way to add another 30 watts to my lighting (DIY) that will benefit the plants and still give them the 6700K full spectrum lighting they need?
