Beautiful ?

Beautiful ?

Thank you!

last 96 hours in the reservoir


The spike and dip in pH is when I pulled the probe to check water I was making for moms, and it dipped down after because I forgot to re enable the doser.

I set the range a little tighter, it's 5.75-5.85 now, +/-0.05 at the plant.

I'm working on smoothing sensor output, while I was doing that I broke my connection to the RTC on both slave mcu on accident. I changed how that worked, before the slaves would request a unix timestamp if theirs was stale. Now, I just send the timestamp out 5 times a second with the heartbeat/res change flag to all connected mcu from the master. It has something to do with class access, because I removed a vestigial debugging variable (the number of samples) and it slowed everything significantly (from like 50 micros to 8000 micros per current sensor). I don't need the memory and it seems like it'll be a time consuming fix so I reverted. Now the clock is working on master/slaves just fine with no sync errors. Another thing I have to chase down is sometimes my milliseconds wont roll over (ie 1.100 1.999 1.050 instead of 2.050) , and I think I can just eliminate that problem entirely by using millis() (the builtin runtime) and modulo instead of using a separate millis() runtime variable.

Destroyed Down to the gnat's ass. With this accuracy, I could see some really nice PH drift experiments and comparisons. Like a smooth curve up from 5.5 to 6.0 over the course of 14 days, or something along those lines.

That's what I'm hoping for, it's pretty close to being usable in that way. The logs are much smoother than before so it'll be easier to spot trends like that.

I've been inspired to get into some legitimate side-by-side comparison and something like this would help stabilize the results. The vision I had, in the beginning, was a 4 x 8 sealed chamber split into 2 separate 4 x4's with separate trays and a sealed divider between. Those 2 trays at first would be fed from the same 40-gallon reservoir allowing for some decent lighting comparisons. Of course, environmental controls would be in order for each individual chamber and that would need to be dialed in and tracked as well. The design would allow you to also feed in 2 separate 20-gallon reservoirs into each side and possibly remove the divider opening up the grow space when focusing on nutrient comparisons. Seeing how you attacked this definitely feeds the fire of inspiration?.

I'm set up right now to have multiple reservoirs and switch between them for different plant stages, but I don't have the space.

I'm keen to see what you come up with.

This would be so amazing for fine-tuning flower transitions and the like.

but I don't have the space.

My current hamstring as well. But I ain't one to grind away daily not to get some personal goals satisfied. The key to the square footage upgrade is understanding how much is enough because I think we all could fill warehouses with our dreams.

I have enough sqft now I think, but I wish for higher ceilings so I can use DE CMH to flower. If anything, I'd just like two 4x4x8, but I cant fit that in my room cause it's got an angled ceiling, so I got the 4x4x7 and 3x4x6. I did get a few more inches in there when I switched the fans to blow through and put them on top of the tents, the led heatsink pucks are spread out on a frame and the can filters wouldn't fit in there unless they were above or below the light fixture.

looks like maybe one more set of weird leaves and then back to normal, took almost 4 whole weeks after switching nutrients to get back to noticeable growth daily without having to compare photos

EC every 2 hours the reservoir gets topped up - green line

pH every 10 minutes a pump kicks on to empty the trays out - yellow line

TEMP about every hour my chiller kicks on - blue line

@dstroy0 @SSGrower I am about to order some more nutrients and was wondering about the consensus on the 2part Megacrop. Is jacks 321 the way to go for a basic mix or is the difference negligible?

All I can tell you is that my garden did not do well on the MC 2 part, and it's doing fine now with jacks. greenleafnutrients definitely made a bad batch of nutrients, and KNEW about it without telling me and instead they let me go on a ton of ratio wild goose chases and such. I was in communication with them about my problems since last August, even though they were aware it was probably their fault, they never suggested as much until I got the jacks and my plants turned from white to green. Then they suggested that it was a problem with some of their chelating agents and the blend, I was beyond pissed, I wasted so much time.

I'm watering my moms in FFOF with jacks at pH 6.5, and they're growing mostly normal now too. I think if I went on too much longer watering with megacrop I wouldn't have been able to reclone the moms and lost those cuts.

Damn, do you think they had similar issues with the 1 part, version 3 as well? I've been chasing my tail for months, trying to get my plants looking right... But I've also been battling bugs, so I haven't been able to pin down exactly what's causing what.

 

[Buck5050]

I'm trying to get my stuff straight before I switch mediums from perlite to coco. I believe @ricky_simples is back on Jacks after a few issues. I also heard someone else mention some pitfalls using the 2-part but they went organic. The winds of change are upon us...

I was an AVID user of their original 1 part, they sent me an updated 1 part that was all powder without balls of calcium nitrate and it sucked too.

edit: they ground up the calcium nitrate on purpose

 

[dstroy0]

they're eating at a pretty steady rate, I'm expecting the pH of the nutrient solution to rise in the next couple of days (still between 5.85-5.75, but it'll hit the ceiling and the doser will dose pH down) if it follows the same trends it has in past weeks.

I have run through enough MC and am done with the company. Nothing they came up with ever matched the original rank ass formula.

With both 1 part and 2 part I see evidence of nutrient excess at the recommended rates, it seems the route more satisified individuals take. The one part, at least the latest version I have, needs Si in veg, Ca and epsom throughout. The 2 part needs Si into flower and a p/k boost in addition to Ca and epsom. Even with that effort the original one part was a better fert and I am still missing something according to Neville's Haze.

I am opposed to edta, I belive it is a persistent organic pollutant. I would also put the other non-essential aminos (dhea, another thats used for iron that icr) in that same group. I didn't want to go with bottles, there seems no other option for dry cheleated ferttilizer, so I am making my own. I am committed to my lab expiriment for the summer.
