Please show me your biggest plant grown in rockwool and the form of rockwool you used.

6x6x6 grodan pargro biggie quick drain block drain to waste. about $4 ea near me.
research I did before using pointed to the 6x6x6 block being the best size for drain to waste.
4x was too small and required more frequent feedings and 8x was larger than the roots needed.
best harvest to date was just over 7 oz from a Red Congolese auto.
typical is 5 or 6 weeks veg and what ever it takes to finish in flower.

Thanks. I may have multiple environmental issues to resolve -- your best was 7 oz, but do you see big variations in results or are they pretty consistent/repeatable?

same strain repeatable for me. if everything else is stable and consistent.
the 7+ was abnormal but prob averaging well over 5 oz per for the strain.
4 oz+ shouldnt be a problem for most I'd imagine. depending on skills of course.
just got 4 oz ea on two original hashplants, first time growing the strain.
rockwool is pretty awesome...grew 54 gms out of a solo cup full.

I use ebb and flow with rockwool medium--4in rockwool cubes on Grodan Unislabs. It is a bit overkill, but the plants do very well and have produced excellent results.

Here is my closest to harvest grow at 39 days of Flower (4x Bahama Berry and 1x Dos Si Dos 33). Flipped on July 9th which was 50 days from clone cutting (approx. 30 days of veg--depending on how you measure it). Some of the tips are singed a tiny bit because it drank faster than I expected causing a brief spike in my EC late in week 4.

Side comment:
Since briefly being on RIU, I have already received some unsolicited criticism when simply providing some details of my grow. I politely listened and chose to defer further comment/debate at the time, as I am new here and don't care to make waves. That said, I am also confident my established process is more than adequate and doing substantially better than the critic's grows they posted, and while many new members are new to the game, I implore others to not think all new users are necessarily inexperienced growers. I love learning new information and being given new food for thought (this happened today, as a matter of fact), but those proffering unsolicited critiques also need to be open-minded and perhaps see what others are actually doing before saying something is "X" in a definitive manner (without referencing citations or anything other than anecdotal evidence), especially when their grows could use some help themselves.

Much appreciated. I will try to not do so. In that same vein, I'd like to tell you that you are doing a great job, so shoot me a message when that happens.
