Anyone knows shops for this?
I don't know, maybe try Barney's?
Also I wonder if all these claimed yields (like 500 grams) are possible without sea of green?
Yields can depend on many things, such as:
1) Plant's genetics
2) Grower's experience and skills
3) Setup (type of lights, medium, nutrients, etc.), space available, indoor vs. outdoor and so on.
The listed yields are part of the advertisings. As, such, IMO, any part of the advertising should be taken with a grain of salt! Also, do they refer to dried weight or wet weight?
500 grams (of dried bud) from one plant, especially grown indoors, sounds like bullshit to me.
If you only grew that one plant AND had used SOG (or some other method to increase bud sites) AND grew it in large container AND used HPS lights AND gave it sufficent room, AND on and on, then you might be able to pull this off. Keep in mind that dried bud weighs substancially less than wet bud, about 1/7th to 1/10th of the weight of wet bud.
If you grew the plant outdoors AND you fimmed it (or other methods of increasing budsites) AND you gave it plenty of time preflower to grow and developed plenty of budsites AND you chose an appropriate strain AND you were able to stalk up the branches (so the weight of the buds did not break branches) AND you were able to supply it with the appropriate amount of water and nutrients AND you were able to tend to the plants a suffiencient amount AND you were able to grow it to maturity AND so on, then one might be able to get those yields.
As I stated before, a stated 500g dried weight yield, per plant, without following some extremely favourable (and unlikely) conditions, sounds like bullshit to me. A 500g wet weight (which would be about 50 gram dried weight) yield would be easily do-able.
If you are getting more that a few oz's (2-4 oz's or 56-112 grams) of dried weight bud off indoor grown plants, then you are doing well.
Thats my opinion!
