Papa_Tanswered grow question 3 years ago What you can do is kinda push it around with your fingers. Move the stem a bit and let it go back to its original position. Gently spread the leaves open. Kinda like giving it a bit of a stretch.
Very gently though. I find it helps promote a strong stem and obviously coupled with proper lighting conditions and they grow strong.
And if you can play some classical music in the tent with an iPad or something that can stream some YouTube. Plants love musical vibrations.
