Use a fan to blow across them gently. This will exchange the air under leafs and strengthen the stocks. If there is stretching then your light is to far away or your light does not have the correct light spectrum. IF you move the light closer you need to watch the temperature under the light at the top of your plants. Don't let it get to hot or you will be sorry.
Zandor Reviewed by Zandor on . stretched plant my plant is 12 days old and im worried the stem is too skinny. I had the light too far away when it was younger and it stretched but then i moved the light closer. What can i do to have a thicker stem? Rating: 5
