Is it growing to fast?

I live in the UK in a city so weather is crap most of the time and space is limited so I'm gonna have to cope with that. I do have a balcony that receives sun from early morning until the evening so I thought an indica dominant auto would be ok. Indoor growing isn't an option for me either for lots of reasons. I do however have a small greenhouse as I do grow other things through the year.

If you plan on growing outside, she needs at least good 6-8 hours of SOLID sunlight. No shades, no cloudy days, nada. They like sunny days (depends on Sativa or indica). Sativa prefer warmer climates. indica prefer cooler climates. At night, you need to bring it in. At 9C you’re going to kill your baby. Or you can put a green house over it. But it seems like you’re not really willing to spend any money for your baby. Cannabis take a lot of time and dedication to get to its full potential. They’re not like tomatoes or other plants that you just let them grow. Cannabis is very sensitive. Especially for new comers

You need more light. She’s becoming stringy because she’s feeling weak. So no, she’s not growing fast. She’s reaching for the light.

Thanks for the replies guys. I have no grow lights and don't plan on spending anything on the grow as such. I moved her outside to the balcony today. Lots of direct sun. Should I pop a bottle or milk carton over her to avoid any damage? It's not hot. 17° and humidity is 65%. Night temps been low at 9° so should I bring inside? Read that a good breeze can thicken the stem. Any more info is much appreciated 😊

It’s not enough light she is growing up looking and searching

Yes that’s normal, love watching them grow at the beginning, see something new almost daily

i'd get teh light closer -- or provide more intense light one way or another. You don't want it to stretch. Energy fuels growth. Light provides energy (along with CO2). The rest is minimal component of it all. So, get some stronge rlight, but don't try to kill it either. 24-30" for cob led - type light to start, but slowly lower as you see it reach (stretch). you want internodal spacing, but not too much. stems will turn paler and get weak when it is advanced. Plants can fall over, if that happens.
