dont know of any chart like this since its very strain dependant and also phenotype dependant.. would be next to impossibru to make a good chart. man your avatar made me trip! your only the second person after myself i see using it even if everyone have it on defult ^^Is there a general chart or something telling you different heights the plants grow for different 12/12 switch times? I'm baked hope it makes sense..
You have 800w HID so if you go by the 1 gram per watt rule you will get maximum 800grams. Of course this is not what you should expect. 1g pw is something experienced growers get and is in my oppinion something not so easy to do. but with some training of your plants , good growing conditions, a veg longer than 2 minutes (lol) and making sure to do your homework so that you have everything coverd i would say you could pull about 0.5-0.7g/pw. But in my honest oppinion expecting certain amount of yield is nothing you should put your focus on untill you know your plants in and out. meaning growing them a few rounds ^^. Hope this helps
