Athosanswered grow question 6 years ago How short is your space? I grow in a growbox that's 1 meter tall (3.3 ft), the plants with training get to 40 to 45 cm tall, sativas even. Check any of the 3 diaries I have here.
In that space I have carbon filter too.
I would top early to stop the vertical growth and promote side shoots. But only 2 weeks of veg might be top little time.
LST and TOP / FIM and supercroping are great in keeping the plant short.
