I'm not doubting your integrity cf fella, but whenever I see statements like this I have to ask what results you were getting with your previous nutes.
Hi papaduc, I would have exactly the same reaction as you to my post had I not written it.
Firstly we are kind of talking at cross purposes because I'm using the hydro nute and you the coco. I cant really comment on your experience but I'm interested because I have a mate to whom I sang the praises of PM who is growing in coco and another mate who is just about to embark on a coco grow for the first time. One will be finished with their canna grow soon and within a week or two the other plans to start up (under glass in a small coco grow) I'd be devastated if I'd steered them in the wrong direction.
My hydro set up is nft,plants are given minimal veg time and then flowered for 8 weeks.I use a mix of MH and HPS.
I have had the room going for 9 or 10 grows. I started with canna aqua because I had used it before with good results and being a new room I wanted to have one variable that I didnt need to worry about .
2 grows in I changed to Vitalink HW as I was using a fair amount of acid and I wanted soemthing that was more suitable to my hard water. The change was easy, very little alteration in the amounts used and roundabout the same results in terms of yeild.
I have poor ventilation compared to previous rooms and low headroom, something I cant really do anything about, all other things were to my satisfaction.
I consistently got around 0.85gpw with my best result being 0.89. I was dissapointed with this at first because in my last room I was getting over 1gpw every time but attributed this to poor ventilation
Then I changeg to PM (different amounts and methods which I'm still getting the feel for) I didnt change anything else and my yeild was up to 1.05gpw and 1.02gpw over the last two grows, I'm on my third grow now and its looking good as well.
I cant explain it, my weed tastes great and burns good ( not ovefed with K ) and I have very healthy rise in yeild.
I'm very happy about this papaduc and I dont see the same enthusiasm on the boards for the hydro range as I do for the ot stuff so I thought I'd chirp up in the hope that a few more hydro growers would let people know their findings.
All the best
