When to turn the light on after sprouting?We have a sprout! Tropicana Banana sprouted between 10pm last night and noon today. Can I turn the light on now, and start the 18-6 schedule tonight or will it fuck it up if I turn the light back off at midnight tonight to begin the 18-6 schedule?Week 1

Affordable but good growlight for small spaceI'm looking for a cheap light to grow one plant, the current one (90w) have just doesn't have enough juice so I'd like to upgrade. I know mars has some good and affordable lights. Any other brands or not so famous brands in Europe that are cheap but good? Tips are welcome!Setup. Lighting

My grow tent is sitting in my basement, which normally sits at 10C in the winter, so I set the heat in the room to 18C and the LED and 2 fans heat it to 20.4C in the tent.
Anyone have a similar setup but using their grow lights as a heat source? Heating a basement is expensive.Setup. Lighting
