Thanks Tom,

yes I can see how bushier growth patterns impact the speed of vertical growth.
Anyhow, when I look at some Arcuata shots around the net I really can get jealous wondering how that could be achieved.

Arcuata has its leaves 1,5 hrs longer unfolded vs. R. rotundifolia (13,5hrs vs. 12hrs) and supposedly needs both higher lighting and longer light periods to grow to its full glory.

Best regards,
Detlef
