No one should have to stake an outdoor plant this early in the season, unless they are unhealthy!
Diffused light making them stretch? No wind or fans? Maybe he's never heard of Potassium Silicate.
Or perhaps he thinks plenty of nitrogen fixes everything. LOL
I'm not defending Bucky, but you know jack shit about plant care or genetics.
There are several reasons to stake a really healthy plant early in life: reduce stress so it grows faster, genetic reasons, Oregon isn't the perfect climate for ganja, etc.
These days cannabis is bread for potency, yield and fast growth rate. This is done by cross breeding sativa and indica sub-species. Most so called 100% indica contains some traces of sativa. Sativa usually grows thin and tall, while indica is short and wide. If indica is given a sativa growth boost, it then cannot hold its weight, even if perfectly healthy. I have an Afghani kush mother developing. It's real potent and growing fast. At two weeks I needed to use a twist tie to keep it up. It's so green and huge leaves for only three weeks old. Today I gave its first LST session. This thing is going to be a monster.
See, even with humans certain traits result in others you don't want. Those who are super intelligent tend to have emotional and mental issues more than those with average intelligence. But everything has its place. I bet those stupid professional athletes wish they were as smart as me and as poor too.
