Oh shit, still cranking out some beauties with the lecs!.........how's your bulb swap schedule? You've had these for awhile now
Hey thanks psuagro, still on the same bulbs when I bought them so getting close to the 2 year mark for the one and 1 1/2 for the other. I thought I had noticed some slight degradation in density a couple of rounds ago. Ordered some bulbs, they shipped the wrong one's, I sent them back and they (bulbs pro) shipped the wrong one's again so still the old bulbs in there #@$!

I'm thinking 1 1/2 years is good, beyond that there seems to be a bit of degradation. I had used the 210w for one round and that's where I noticed that plant was a little more dense (same strain/clone) than the previous one under the older lamp. Cheers.

Cam view of the flower room at Day 51 and Day 11. The 2gal's at the back continue to build bud and weight, a couple of these phenos have really tight buds. The most dense is the front-left which is what I'm calling the JTR pheno, buds are solid rocks :)

The newer 4x 3gal are stretching out well. Close to 3 x 3.5' now after 11 days and buds are popping up.

One thing I did this round about 2 weeks into the 9x 2gal plants is running the temps pretty well even lights on or off. Hitting as high as 82F and highest temps lights on are running about 80F. It had gotten warmer and the heat wasn't coming on so to manage RH I started running my de-humidifier lights off and didn't vent it so the heat it generates warms up the room lights off. This is trying to get to negative diff, or higher temps lights off which is supposed to produce more bud. It doesn't seem to be hurting :) This round was just to see what if any differences there were since I'm running seeds. The new batch is more of a control batch as I've run those for a long time, all clones running 1 year +. The only thing I've noticed is more uptake and likely higher evaporation so I've had to water more often, those 2gal's are bone dry in 36-48 hours, partially due to the small pot size and large plants but I'm sure the higher temps contribute to it as well. Other than that it seems to be building some nice colas at the back :)

tropical fruit/blueberry sounds fantastic. Good luck with the hunt! (should be fun ;0)

BTW: You post in the thread "Seed Pictures" don't you? You should repost those
seed shots for Mo. :0)

JD
Hey JD, would be a nice combo to find in there. Lol, I'll have to take some Mo-worthy close-up pics before I post them up in that thread ;)

I'm glad to see someone finally trying the negative temp differential! It'll happen on accident this summer for me, but not much for me to say about it until then :)

Temp differential... they've got a name for it... and here I thought I was just screwing up! I've got the same situation, dehumidifier running when the lights are out causing the same or sometimes higher temps during the dark period. This can be a good thing? Ha! Maybe I got lucky.

I've been having problems with RH and nighttime temps for a long time and I'm finally about to install a piece of equipment I've been looking forward to for a long time; a chiller with hot gas recovery. To cut a long explanation short, it will allow me full access to the rejected heat from the water cooling system. I'll use this heat to keep my nighttime temperatures at or even above day temps and for closing the dehuey loop.

I plan to put this hypothesis of better yields from high night temps to the test!

Doesn't look like it'll hurt right now. Will be keeping a close eye on the newer batch, JTR, Blue Dream and one of each Blue Ripper pheno that I've run many times and in different pot sizes.

Lol, no worries, the general thinking has been to have a 10-15F difference between lights on/off but negative diff is supposedly better for building bud. We'll see...

That'll be a great way to try it, no cost and possible benefits, looking good over here so far. New round will tell me better with some control strains/clones.

Cheers.

Awesome! Good to hear! This new beast will allow me to fully control the environment in ways I've never been able to before, so I'm looking forward to lots of experiments like this!

It will be interesting to see if you can measure an increase in bud growth using this process.

:weed: :clap: :clap: :clap:

The way I measure yield is dried and cured, every time. It's the only number that gets any respect anyway, so that's the benchmark here. If a technique boosts quantity or quality without sacrificing too much elsewhere, it's in. If not, it's outta there!

I've slaughtered plenty of sacred cows of the growing mythology variety here, many of which were fondly held personal beliefs! That's what I built this place for.

Yeah, agreed. I have documented all these clones at one point for dry yield (I don't always bother as I don't grow for yield, but any new strains I weigh a couple of times for reference like when I'm trying something new like this). Another one I've used for reference is not only the weight but ounces yielded per gallon of medium. So for instance I know I haven't been able to get past .75 ounces/gallon for the JTR pheno I'm running, no matter whether straight up, minimal training, lots of training, different container sizes etc. For the Blue Ripper 1 pheno I've hit as high as .95. So if I got lets say .8 or .85 JTR and 1.1 for the Blue Ripper, that would be a noticeable/measurable difference. I won't use the Blue Dream as a reference as that plant was small and not in the shape I'd normally put it into flowering so it wouldn't give me a good reading and I haven't run the Blue Ripper 2 enough to establish a proper baseline. I also won't change the bulb out even though it's due for that 3x3 until it's done as I don't want to skew the results with a fresh bulb. Still other potential variables but most are as consistent as I can have them other than this difference in higher temps lights out.

So the baseline target for JTR running in a 3gal pot if all else goes well should be ~2.25 oz. (3gal x .75), anything over would be a bonus and could be attributed to the environment. The Blue Ripper 1 plant would have to surpass 3 oz. dry.
