There are lots of variables. Strain type, veg times, proper training for maximum light exposure, air exchange, proper feeding, bulbs, etc.etc.
Well, isn't there some kind of guide for maximizing yield?
As far as I know, I have almost everything right.
I'd love to see the thread if you can find it, but those numbers for me don't jive keeping it real.
Multi found it:
here
33oz cured (924g)
600w
1.54gpw
x9 Kaliman Cheese
Yes, that's the one.
I have two questions:
1.) How did you get a 30x30cm plant to yield as much as a 60x60cm plant? If plants size is directly comparable to yield outdoors then indoors yield should be directly comparable to the amount of light. If I have 1000w and two large plants, they should both yield 500g, while smaller plants would yield say 250g each, no? So, what is keeping plants from reaching that 1g/w?
2.) You say "900g cured". Is the cured weight higher than the dried weight? If you simply dried the buds outside for two weeks, what would the yield be then?
Get your temps in line 1st and buy an ec meter so you can test the ec of your municiple water and your mixed nutrients.
Would an EC Meter be able to accurately gauge the amount of nutrients I need or would it just convert ml to ppm? If so, why is it necessary?
My belief is that you are trying to run before you have learnt to walk.
A better analogy, in my mind, would be that I am walking slow amidst a herd of joggers and attempting to ask each one as they pass me how they do it.
I did the same thing in regards to computers and hardware. I asked enough questions that I became the jogger, then the runner.
You "will not" achieve great gpw until your grow space is fully dialled in and you have gained a lot more experience.
Can you give me a checklist of items I need to check to know if my grow room is properly dialed in? Like lights/sq. meter, temps, etc.?
I think I'm like 70% dialed in but I'm not sure.
I tend to run x4 indoor harvests per year, typically in my circumstances, the winter/early spring and fall/winter harvests are better than the late spring and summer harvests due to the outdoors ambient temperatures as I do not use AC
Yes, I have found the same to be true for me, living in a pretty hot climate (32C average for most of the day in the summer)
If I do indeed get better results in the fall/winter then it would be proof that my temps are simply too high.
IMO your 1000w lamp and ventilation system just aren't working in your favor. You have constantly been experiencing high temps during your last 3 grows. The easiest and quickest solution to your woes would be to lower your temps. I believe that the easiest and cheapest way for you to achieve this would be to use a 600w instead of your 1000w rather than upgrading your extraction system.
But then I'd have 600w in my 4m2 area. That's less than half the minimum recommended.
Also, I was under the impression that you shouldn't exceed removing all the air in your grow area in 2 minutes because anything faster wouldn't allow the plants to draw in the oxygen and C02 from the air.
This is why I chose an AC, as it seems the only option viable for having a lot of light with high ambient temps.
P.S. What is that photo of in your sig and did you take it yourself?
