I find the curve between pot size and root growth and yield to be non linear.
But we grow - we grow not just coco - we can water so often the medium becomes less important.
We are flood/drain - its not quite the same - the coco (whether or not
@Bill284 stlye with bokashi and frass,
@DYNOMYCO that the coco growing of which you speak - and honestly amazeballs.
Like for anyone starting out growing - if not a SIP - I dunno soil scares me a bit!.
<The Streets of Philadelphia just came on my Spotify - even for me tonight I've been weirdly lucky!>
So yeah with flood drain you're closer to DWC but not quite. Roots ain't a problem. And you neet to get your numbers clear:
We grow in 4 main sizes - and its so much easier to use milliliters:
So I made this.
Thinking about it.
Its hard to judge, small sample sizes, stuff like this grow the light breaking, other stuff we're always changing something, so many variables!
But yeah that's pretty much I how I see it.
Look - my numbers are sort of fuzzy - we've pulled 88g I think out of a 16oz solo, a couple of Mimosa Orange Punch. Epic yield strain tough, but under HPS 1000w DE ina 4x4 - so think I can do better! The 5 Gallons -sure you can get a bit more that that out a 5 gallon - but the extra cost in grow medium and light - you need them really big hit that weight.
AS I said last night in my journal - I'm not actually that comfortable growing in rockwool. Hard to recycle. Coco grows here in Thailand - its probably the more sustainable, nothing fling round the world. Environmental impact stuff.
But yeah. The massive farms in the US - lots grow in Rockwool so I'll give it a whirl!
We also grow high plant density. Sure like most the board beaten our record single plant weight.
BUt yeah - we're not abolute classic coco growers. We water way more than near anyone else does.
Its a slightly different beast.
Anyway spreadsheet below.
Root growth - I think it costs vertical growth. Stressing them with space yields.
