Started a couple of NL seeds (strictly for experimental purposes) about 30 days ago. They were both germinated straight into soil.
30L pot (about 8 gal) with top soil (16-11-11) and 40% perlite. Bottom of the pot was filled with 2" of small pebbles for better drainage.
During the first 2 weeks they grew at a normal rate.
Gave em a root stimulator and 4 days later they were growing like crazy. Doubled in size!
Waited a few days and watered with half dose of HY-pro (canna specialised bio fert)
Here are the results. One is almost 13" and the other one about 11". They re both in the same pot.
