Best light schedule for autoflower?

I have an 11 day old amnesia haze autoflower under my mars hydro 300w and im wondering, how long can i keep it at 24h light?

As long as you want. The optimum lighting schedule people use most often is 20/4 though.

What are the problems with 24h?

Ran for 24 till I flipped the photos I had about 8week

Some people like to give the plants a 'Break'.

Haven't grown many autos, but general wisdom is that plants need some down time as part of the natural cycle. I've heard 18/6 and 20/4 mentioned by most auto fans, some saying that you don't really get more production/weight running 24hrs straight and you're just running up your light bill.

I also remember some weirder cycles - thought I read some grower who went with a continuous 12/6 rotating cycle, another 12/5/2/5 or some such (claimed a real increase, your mileage may vary, lol), but the point being you just need to find what fits you best as you gain xp. If you plan on running autos for a while, you might want to switch up between grows and compare yields, BUT to get realistic/accurate data, you should run the same strain imo.

Thanks, just what I needed!

Should I switch my autos to 12/12 after they start to flower, or leave things at 18/6?

Do not switch to 12/12. Leave at 18/6 or crank it up to 24. The more light the better for autos.
