How does root crowding effect growth?
Reason why I ask is I am already having root issues in my hydro garden. I’m having plugged drain lines and roots are making my plant tubes overflow periodically. I’m a little worried about it at this point because I have so long to go before harvest. Should have used 6” pvc and 1” plus drain lines. I’m going to totally revamp my set up next year based on what I screwed up this time. Lol just trying to get the most out of my crop for this year as well of course.
Well that IS the critical factor in my opinion. (Assuming all other things are correct such as pH, nutrients, etc). The roots are the way the plant absorbs water and transports minerals and nutrients up the stem to the leaf factories. So obviously, if the root volume is limited, the plant will not be able to support more than a certain amount of canopy. But obviously it is wasteful to provide a larger pot than the plant can use. (I'm mainly talking about indicas because... well, 12 ft sativas y'know.) And also, if you're using lamps, there is not much point in blasting them with more than the root system can deal with.
 
Afternoon ya O'l potheads. Total of 9 flats of flowers and all veggies are in the dirt and pots. Now get to watch everything grow. Just like marijuana. Never thought in a million years that I would spend my senior years growing shit. Pretty much all I do these days.

I am impressed with your amazing planting expertise. The climate here is too hot for most things. But I am trying some passionflower bananafruit, Bee Bee tree, Bulbine natalensis, couple other exotics. Going to try Hass avocado.
 
Good night OFC. Been a long day. But I got a lot done and can finally relax. At least for tonight. Stoned and my head feels really good. Thinking that is why I bust my ass during the day....to get wasted at night. Never have really wanted to get to loaded during the day I like to fiddle about while the sun is out and drinking and smoking leads to to much couch sitten.....


Back to getting my head bad..

Has anyone done a study of yield vs pot size? Obviously using clones of the same strain. I'm thinking that probably it begins as a straight line graph and then as the pot gets large, the line will go flat as the natural maximum plant yield is reached. For instance, I bet the yield is similar for an indica whether a 5-gallon or 10-gallon pot is used.

I can say that 2 OG Kush in a 5 gallon gave no where near the yield of one of the same in a 5 gallon pot, genetics, light, nutes all the same.
Plus, the speed of the growth was much faster.

You mean, both of the (doubled) plants together, yielded less than one in the same pot? If so that's interesting. It implies that competition for resources inhibits the growth of both plants. Which is logical... it's known that many plant roots put out substances that discourage competition. That's a very useful piece of information, Bubba.
