nice shit man one more notch in the belt, and now we are off again already... truly amazing. How long have the colored pots been in flower?
Hey Riddleme I was just re-reading this thread and had a couple questions if you don't mind. You said a ways back that you found a good deal on the calcined clay balls. Where did you source those, and what was the cost? Additionally I have been trying to find a resource for the Jrpeters nutes you suggested and have not yet been able to find a source here in the west. Did you order those direct from Peters in Pa. I'm on about page 60 and have not yet found your reference to PH in the #4 mix. I know the rain is 5.8, but can't remember your nute PH. I found a product called Pro mix bx http://www.pro-mixbas.com/ Is this similar to your #4? Would the nute PH be similar? Sorry for the cavalcade of questions.![]()
yes they are, just finished, wet wieght comming in at 2395 gramslet the guessing begin
remember I leave the leafs on
pics & updates comming
Thanks for the quick reply. I noticed that the Pro-mix has some dolomite, but had planned on amending it. Is it possible to overdo this?
Thanks... Was planning on one tbl spoon per gal. of Pro-mix.IMHHO as for buffering of ph it will never raise it above 7.0 but as to causing nutrient blocks per too much calcium magnesium if you go crazy, but otherwise I think you are fine...
Hope it helps..

How bout them Raiders there RM3? Gotta love it when 'Just Win Baby' is back !!
hey riddle, what was the actual time on cooking the popcorn buds?
I was reading back over this thread & found about 2 whole pages that somehow I missed....it was important info too. I'm glad I reread stuff every now and then

RiddleMe, How long before you start the new garden IR heater experiment. I was just wondering sense you added another light are you going to add another IR heater and when can we expect pictures?
Great info. Thanks. That's interesting about the CO2 concentration in field soil and its affect on PH.Ive wondered about this before, which is why I contacted Bill Argo a few months back to ask about the possibility of overliming. Bill Argo has a great series called Understanding Plant Nutrition and he is the man to ask questions about media ph.
This is what he wrote back to me:
Will Dolomitic lime get the pH over 7.0? The answer is yes, but it may take a while to occur. The solubility of any limestone decreases, as the pH increases, so the reaction rate of limestone slows dramatically once you get into the high 6's or low 7's. However, just because it slows down does not mean that it is stopped. If you overlime a media, you will eventually react an equilibrium pH. As long as there is free calcium present, this equilibrium acts as a pH buffer (i.e. the pH will not go above this equilibrium pH)
With limestone, the equilibrium pH is dependent not only on the calcium concentration, but also the CO2 (gas) concentration in the soil. At atmospheric CO2 concentrations, the equilibrium pH is around 8.5. At higher CO2 concentrations, the equilibrium pH is suppressed.
Since container media are highly porous, the CO2 (g) concentration measured in a media is similar to atmospheric CO2, and so the maximum pH you tend to get in container media is around 8.5. In field soil, the CO2(g) concentration is often reported to be 10x higher than atmospheric CO2, and so the equilibrium pH is lower (low to mid 7's). These are what are termed calcareous soils.
Hope it helps.
