I'm a bit confused then. You are running the test for 2 different nute brands on a single flood table? How are you doing that?
Dyna-Gro vs Advanced Nutrients Connoisseur (AK47 Grow)

Unless I specify otherwise, the only flood table you'll see in this journal is the one where I'm growing AK47 with AN's Connoisseur.

hb do you not use overdrive i find this frosts my ladies up real nice

I'm not going to use the product 'overdrive' but may throw in something like a koolbloom or florabloom which is the same type of product. Maybe one of those would account for 10% of my total ppms, though I'm not sure that it would make much of a difference. As a general rule of mine, I like to fill up most of my ppms with mineral-packed products like high quality base nutes with desirable NPK ratios and not dilute that with incomplete boosters.

i have never tried koolbloom or florabloom so would like to see your final results,as you can see i am not an expert an learn from threads like this off you guys thanks for the input

My most recent numbers are in from the previous AK47 grow in the exact position where I'm conducting this comparison. The yield was 560 grams on the dot (20 ounces) which makes this the fifth consecutive grow where I've achieved a minimum of 20 ounces from this AK47 strain using DynaGro. This is a pretty well established benchmark now so we'll see soon enough if Connoisseur has what it takes to surpass my favorite fertilizer.

How long are you vegging/how tall are your plants when you flip?

I don't like them to be any taller than about 15 inches but it has more to do with their structure as to when I'll switch them into 12/12.

Hey HB, I'm planning to do a 6" rockwool cube ebb&flow grow myself, and since you've had lots of success with this method I want to ask you about flood depth, or how far up the rockwool cube you fill the tray? I have little experience with rockwool and don't know what the wisdom is on this? Thanks!

What structure are you looking for?

My flood and drain system probably only floods the bottom 2 inches of the rockwool cubes. The cubes to a good job of wicking up the water and the roots don't seem to have an issue pulling up food.
Bushy, lots of branching. It depends on the strain but I like as many strong growth shoots as I can get.

Are you training the plants at all, topping, fim, lst, etc?

I always top them in veg and always supercrop in flower. Depending on how fast they grow, sometimes I'll top and supercrop in veg. The ultimate goal is to have a nice bushy canopy which will turn into a plethora of colas at harvest.

nice thread. excited for this test. i use sensi bloom 2 part right now and i might or might not get the conni line depending on how ur girls turn out. sensi is working fine enough for me and its only 27 for 1 liter of each compared to what like 75 bucks or so for the 1 liter a and b? hopefully it produces crazy yields. im subbed.

Day 14 today and I'm updating a day early because work has called me out of town for a week. The next update should be on the 27th.
The ladies look good and by all accounts, things look how they should. The plants are branching and bushing-out as expected and I've installed some trellis netting to support the yields that I've come to expect from this strain (hopefully it's needed). Over the past 2 weeks, I've been taking some notes about Connoisseur's pH stability. For you non-hydro guys out there, the pH is something that can get out of control in hydro if not monitored daily. Write up below:
pH stability: Connoisseurs pH stability is similar to that of General Hydroponics when used with RO water. Typically, Ive needed to pH the water 3 times per week with Connoisseur and I think one of the reasons for this is the lack of buffers in this fertilizer. I say that because one thing that I noticed right away was that it didnt take much pH up or pH down to move Connoisseurs pH. So when topping off my res with RO water that has a pH of 6.0, that seems to cause the pH of the Connoisseur res to move closer to 6. I run DynaGro at 5.7-5.9 and to make this test as identical as possible, Im running connoisseur in the same pH range. So while Connoisseur wants to drift closer to a pH of 6.0 when topping off with RO water, this isnt out of the range for nutrient availability and probably wouldnt cause any issues for lazy growers. Though I do not know where the pH would go should the res go unmonitored for a week. For more attentive growers however, it does mean that during the first few days after a res change, one needs to make sure theyre monitoring their reservoirs for the best results.
DynaGros pH on the other hand is rock solid. The only time I ever pH the solution is after Ive changed the res and even then, it falls into the 5.6-5.7 range. I do a quick adjustment to high 5s and it always seems to stay put. Even when topping off with poor tap water with a pH of mid 7s, DynaGros pH just doesnt want to move.
Overall, the pH performance of Connoisseur isnt bad but its not nearly as hands-off as DynaGro. Im out of town this coming week but when I return, Ill be running Connoisseur with tap water for a week to see how it does.
Connoisseurs pH log w/ RO water:
Thursday 6.7 (Fresh res, adjusted to 5.8 )
Friday 6.1 (adjusted to 5.8 )
Saturday 6.0 (left alone, wanted to see where the pH goes)
Sunday 6.0 (Adjusted to 5.8 )
Monday 5.8
Tuesday 5.9
Wednesday 5.9
Week 2 w/ RO water:
Thursday 6.8 (Fresh res, adjusted to 5.8 )
Friday 6.0 (adjusted to 5.8 )
Saturday 5.9
Sunday 6.0
Monday 6.0 (adjusted to 5.8 )

One thing I want to point out is the difference between DynaGro and Connoisseur even at 2 weeks into flower. The first picture is DynaGro at day 15, the second is Connoisseur at day 14 (same picture as above). I'll let you decide who has the advantage.
DynaGro day 15....
Connoisseur day 14...
DynaGro day 15....
Connoisseur day 14...
Great experiment. I have been wondering about this for some time now. I'm assuming you're using dyna-gro bloom formula, right?
