For the first time this season, the flash on my phone decided to go off when I took a root shot. I thought I was seeing everything without it (and never forced it because I thought it would over-expose or create reflections) -- but it is showing a lot more detail. The first time I grew in a sip I used an air stone, and in that grow 90% of the water roots that formed were in the bubble stream. I've used air stones ever since.
This time I have roots both inside and outside of the bubble stream, but it looks to me that the ones in the bubbles are denser and whiter, and I think I've read that whiter roots are healthier? It's also interesting to me that the roots in the bubble stream are poking above the surface of the water. In case it's not clear, the area to the left where you can see bubbles on the surface is where the air stone is sitting on the bottom of the res.
Every other fill I'm adding a little bit of Hygrozyme to the res, and about every third time some Silica. I'm adding three big shots of pH "down" every time. That seems to be helping a lot. For my non-sip plants I'm top-dressing with Dr. Earth's acid lovers dry time release nutes, I think that with each watering it will break down a little more, hopefully counter-acting my high pH tap water.

Thanks guys. 
I've been pondering pot size with sips, since beginning with this run I'm starting to experiment with longer veg times and larger plants (in an attempt to only do one indoor grow per year and net 24oz+/-.). I'm thinking that even if my "trench" of nutes was big enough to hold enough nutes for the whole 17 week grow (@8 weeks veg and 9 weeks flower), I'm wondering how much "root crowding" stunts the plants? Anyone have any thoughts on that?

hmm that would be one hell of a plant lol I have seen 1 plant 1 lb threads but never 1 plant 1.5 lbs! But Im sure it could be done with the right set up!

Not one plant -- combined harvest from a 3x3 tent and a 2x4 tent, with 2 plants in the 2x4 and either, 1, 2, or 4 plants in the 3x3. Still working on what the best combination would be. I'd need 12oz from each tent. My bad, I wasn't clear about that.

oooh ok i see what you mean i would think with that square footage you should be able to do that.

I was pulling 8 to 10 o's off the 10 gallons I was using prior to going to 20 gallon no till sips! I'd expect 12+ off the 20 gallon sips.....I'll let ya know in 6 weeks!

Yes, I think it’s possible to over veg a plant in a SIPs depending on the size. It’s harder than a regular pot, but still possible. But, with a large SIPs, probably unlikely. I think a root bound plant is going to have a harder time developing robust flowers.Thanks guys.

My Lemon OG is stretching like crazy. The Critical Cure is a bit more compact. I’m almost at the end of week 2 and hoping the stretch is over. I’m running out of room. I could have maybe done a one plant SCROG with the Lemon OG. Did some defoliation to open things up a bit.

Looking Great @PDX Joe ! I am very worried about the stretch I am going to get when I go to flower for sure I will be tieing the ladies down for probably the first 2 or 3 weeks of flower in an attempt to keep them lower. Same to you @Tim Fox ! Also I think my next grow I am going to try to do some aggressive mainlining and training try to get just 8 massive kolas per plant. I have such a hard time trimming things off though lol I have read so much debate on de-foliating and not... and I have done it and seen the results...I dont know just seems counter intuitive to cut away parts of the plant that are healthy.

I'm struggling with defoliating also. On my GG4 in the sip, I stopped trimming because my understanding (which could be wrong) is that as leaves yellow late in a grow the plant is "cannibalizing" (or recycling?) nutrients from the leaves. I'm trying to leave some extra leaves on this plant so that if I don't have enough nutes in the soil to carry it through, at least it has some extra leaves to pull from. My logic might not be based on how things actually work though, wouldn't be the first time.

That sounds right to me from all that I have read on here.
