I've been growing now a few years and would say i have become pretty successful. I can't believe i have never researched the whole ppm of fert regimines. i am a soil grower and keep it p.h. at 6.5-7, with proper ferts so i think. For the past couple of days i have been trying to find a proper thread on the explanation of ppm. could some one point me in the right direction?
If you are in soil, that's why you have never had to worry about ppm.
To find that sweet spot, soil growers can simply start off at a lower level of ferts, and ramp up until you see some scorch, and then let off a little. Record where that happened, and give just slightly less, flushing well every so often just to make sure that you don't get any salt buildup.
If you're still curious, there's lots of ppm talk in the hydro threads. Weedhound's grow log is very interesting.
as far as I know, ppm only is monitored during hydroponic grows ... go to the Hydroponic section, those guys will answer your ppm and tds questions, I bet ... :smokin:
ahhh, I see Stinky and I posted at same time ... dammit, woman, you're supposed to stay 3 steps behind, don't ya know that ?? ... :D
thank you all.. i just explained my current situation in stinkys "styles thread." i was following white widow 2007, and became intrested all of a sudden. This is the first time I am fully incorporating nutes in my cycle. Fox farms veg and tiger bloom. I started a thread about working with but went sour do to space and heat issues. now just working in a few spare rooms in the cellar with a 400 and 600.
