Tall and Thin?

Heat can also be a problem but lighting is typically the culprit. Check out King 1500w LED on Amazon. $150, cooling system installed and is powerful. Something like this would be enough for a few plants or one very large one.

Probably for the low power of light she take, she stretching because need more 😉

hi i looked at the info on the strain and from what i see is your light is not strong enough. no worries though also the plant will stretch during the preflower, here a chart to help you with autos, they usually follow this: 3-5 weeks are the vegative stage 4-6 weeks is the stretch phase 6-10 weeks is typically the flower stage so next time a stronger light. also you want to pick up some all purpose food, like a 20-20-20 mix, these mixes have everything the plant needs, including micro nutrients, give this to the plant during the veg and stretch period, you will see a big improvement in things, with your plant being so tall i would not stress this too much, if your needing the room and dont want those buds touching the light you can lightly bend things down. hope this helps
