Almost forgot to do an up-date on root pruning. The first time I pruned them, it took about three days before they started growing down again. Its been 5 days since I last pruned them, and they still have not sent any new shoots down. Im kind of impressed with this.
Of course, they have spent most of these last 5 days recovering from major stress, so that might have something to do with it.
Day 33
Time for some random thoughts and up-dates. It should now be at, or past the 1/2 way point in the grow. I am still concerned about the small size of the plants and how close the nodes are - but - they do seem to be growing faster every day.
It looks like Im going to end up with a single cola on the runt - even though it got the same FIM treatment and I have been trying to LST it the same as the others. The middle child looks like it will have the two that split after the FIM, plus two more from lower on the plant for a total of 4 colas. Big sister will have at least 6 and maybe 8 big enough to count, plus a couple of smaller side branches.
The roots are doing pretty good considering all the stress they have been through. There are several things with them that I find interesting.
There seems to be three different zones going on - upper, middle and lower. Growth in each area is quite different.
In the upper section I see the fattest bottle brush style fuzzy roots. These roots have the largest and the thickest fuzzy bottle brush look. The top of the chamber is also the driest of the three in some ways and the wettest in others. Its wettest because the nozzles point UP and the main blast hits the top of the chamber and spreads out from there and then drifts down. Its the driest because the mist settles due to gravity, so the mist fades out or has the shortest hang time at the top. It will also see the smallest average droplet sizes after the initial blast - the larger, heavier droplets settle much faster.
I have only guesses as to why, but the middle section is the worst looking/slowest to recover of the three zones. Thats counter intuitive to me, so I can only guess its something left over from the die back each time I left the nozzles turned off.
The bottom section looks great compared to the middle section and that kind of makes sense to me. That area will stay wet the longest and see the most mist over time.
This wide angle shot shows how dramatically different the zones are. The tap roots also show up pretty well. These are hanging down a total of about 26"
If you zoom in on this pic, you can see that there are now just a couple of small shoots that have made it to the floor of the chamber. I am really impressed with this root pruning thing. They take to training pretty well 
I find it funny that the roots want to cling to the ceiling and grow down from there.
I was concerned about slow growth myself. Just wait mine went from this on Sept 13
When yours take off its going to be interesting to see how that style of hydro does. In dwc they go apeshit lol
OMG! Your babies are only three days or so older than mine, but they are huge in comparison!
LOL they are going to have to do some insane stretching to catch up, but my fingers are crossed.
Well you saw how fast they take off on my thread it was like little bushes one day then i opened the tent the next morning and was like omfg lol i was getting 3-4 inches of vertical growth a day for a week and a half. Thank God they slowed down I’m running out of height. So far 95%of the tops have been flopped already and I’m thinking i may be in the light before they finish
You got any other autos? I’ve got the sbr x cherry something lol to try next. Gave half the gosttoof and alaskan purple to friend to try. Hell if you were close to me i got a bunch of moms that need to be cut back I’d give ya all the cuts you could handle lol. This morning i cut 2 back a little and what i cut off could have produced 15 clones. Thinking about rooting a bunch and taking them down the tracks by the mines and let them do their thing on their own and see what happens lol
Day 34
I have some of the two different CBD strains from Sebring seeds as well as a few Ghost toof x sbr left over that I didnt use. Im still debating what to run next time around.
I had been planning to run the Sebring seeds because I want to try something with more CBD, but I may go a different route. It will be some type of auto though. Even if this is a tiny harvest, I still like the idea of autos. Im sure that next time I grow one of these, they will do much better - IF - I can keep from killing them by turning off the darn misters!!
In the mean time, they are growing faster every day! They still have a loooooong way to go to catch up to your though.
I saw you are feeding these a lot heavier than I am. Ive been keeping it low due to droplet evaporation raising the EC, but some of the leaves still look a little pale, so Im going to jump up from EC 0.8 to EC1.0 and see how they like that.
In the mean time, I got some more interesting root pics.
That spot on the ceiling where the roots are growing down is one of the wet spots created by the nozzle shooting up at the ceiling. It almst looks like there is another net pot there.
The roots are starting to hit the bottom of the chamber now. Its almost like they put one toe in the water to see if it was going to get cut off, and now that its ok, they are growing down again.
The right runt doesnt look like it will amount to much, but the left one should be good. They should still double in size once they start flowering. I’m sure they would be doing a lot better without the few times drying out.
No they will triple or quadruple in size mine did and then some lol. Sucks being 1400 miles from my grow right now
Day 38
LOL
I was originally thinking that @ReikoX prediction was what I would see - at best. I started recording time lapse pics, and they just were not doing much growing. However, the last couple of days, the bud sites have started developing with some good looking pistles showing up in many places. That seems to have triggered faster growth.
At this point, Im starting to think @Daytripr69 may be correct as far as the final increase - which would be awesome.
One interesting and unexpected thing - the runt is catching up to the middle child - and may even be slightly bigger now.
First - are these balls???
Here is today vrs two days ago. There isnt a huge difference visible in the pics, but what you dont see is the vertical growth. They are a good bit taller.
Some more root pics. Im addicted to root porn, so you folks will just have to put up with my vice 
hard for these eyes to discern 
the hairy pistil female parts no, the red nubs below, maybe… is that a male flower on the blue part? 
Doesn’t appear to be any male flowers. Holy pubescent tho, she’s furry af, huh 
Exactly what @cannabissequoia said. The part on the blue maybe. But do keep an eye on those lower nodes. I’ve seen two or three of this cross do that.
Thanks folks. I will take a closer look and see if I can get some better close up pics.
I dug out the macro lens for much better details on those possible ‘balls’.
In this case, the red spot is just where I did my FIM a few weeks ago.
I don’t see any bits you wouldn’t want there 
Yep just swollen cylax and pistils in those pics. 
Thanks guys! I have been more than 1/2 way expecting to find some hermies considering all the stress Ive put them through, so this is good news.
Day 40
Ive been making gradual changes in some details.
As the plants started to grow, I have been decreasing the OFF time while keeping the ON time the same. This has the effect of increasing the flow rate of nutes to the root chamber. I was at 0.6/45 at the driest setting. Thats aprox 1.05 gallons/day. Im now at 0.6/30 for about 1.57 gallons/day, which is a significant increase. My rez was lasting over 7 days and its now down to just over 5 days.
As suggested by @Daytripr69, I have been increasing my Mega Crop dosage a little at each rez re-fill. Im now up to EC 1.6 from my starting value of 0.8. The leaves look greener and still no signs of nute burn. It seems like I have been to cautious about evaporation raising the EC in the droplets.
The plants are really starting to stretch and the roots are still growing like crazy.
I think mine are still behind the curve on size, but they are sure trying to catch up. They have at least tripled or quadrupled in size in the last week! The other interesting thing is the runt is now clearly in second place size wize. It has grown tremendously the last few days and way out paced the middle child.
One week ago vrs today.
Im still fascinated by the roots growing down from the top of the root chamber. I have two separate clumps - one in front and one in back of the row of net pots. They are both getting quite large. Its almost like I have 2 more net pots throwing down roots. Im sure they wont, but I cant help worrying that they will get too big and heavy and fall off!
Excuse the hairy arms and the bath robe. Just be glad I wasnt naked…
