How to get AG spacesaver6 on 24/0 lights?

the AG spacesaver6 doesnt have 24/24 light cycle, the longest one they have is 17/7, which is not enough for shit, any tips on how to make it 24/0?

If it has the "lights on/off" button on it then just push the button and it will stay on indefinitely. Otherwise, ur fuct, take it back to Bed Bath and Beyond. They sell them there and they'll take it back with no receipt. You'll get a store credit where you can buy the deluxe 6 at the store or on their site. The deluxe 6 has 3 lights and a 24hr cycle.
