This is a pretty good Read right here. So I recommended the Mars ts-1000 because you are in a 2.5x2.5ft tent and the mars veg foot print covers 3x3ft area so you are more then covered and if you decide to flower it’s bloom footprint is 2.5x2.5ft... perfect. It says 150watts but this is dimmable and I believe if turned to 100% it actually draws 185watts... either way the dimming capabilities of this light will be of huge help to you as your plants grow you can increase wattage... I believe you’ll see the results for yourself when you put it into action, that’s the perfect light for your size tent and with what you plan to do. Glad I could help ya out buddy!
