use metal halide during the vegetation cycle
I didn't want to get technical Joker but you are correct.
The HORTILUX Daylight Blue Metal Halide is by far the world's most powerful grow light.
This grow lamp produces plants with extremely tight internodal spacing for nice compact, bushy plants.
They are a little pricey but well worth it.
Then after six weeks of running them for 18 hours switch over to the high pressure sodium to 12 hours to finish them.
The high pressure sodium grow lights provide the warm spectrum (reddish and orangish end of the light spectrum).
This spectrum helps make big sticky buds.
A lot of people use HPS from start to finish because they cost less to buy, cost less to run and don't run as hot as a MH.
Since weed has become legal to use and grow in Michigan people (21 to 81 years old) are becoming a little sketchy in reeking like it when they go out in public.
They use to cover the smell with cologne buy now no one cares.
Making it legal to grow sure knocked the hell out of all the illegal money that was being sent back to Mexico for it.
Now it is a Billion dollar industry creating a huge tax base with all the Billions staying in the U.S. instead of going back to Mexico tax free.
That's what I hear anyway.
Poland should cash do the same thing to make money on it in taxes instead of spending money on it trying to enforce a frivolous law that nobody abides by.
