Narrative:
Leaving ZZZ to ZZZ1. I forgot to turn the bleed switches on at acceleration height. Our takeoff required the bleeds to be off. We got a cabin press warning at cruise; to which we noticed the bleeds we're off and we turned them on. This cleared the cabin press warning and pressurization was normal; I went over the east&a checklist to confirm everything. We didn't execute an emergency descent as it wasn't required. Flight continued on with no incidents. Same as above.the early morning; plus the dark cockpit led to me noticing the bleed switch position. In the dark; the switches appear normal. A technique taught during sim is to touch the bleed switches during the acceleration height flow. I'll definitely be using that technique from here on out.
