Well the setup is 95% done.
The rdwc change to 1.5" pvc is working perfect. No leaks and fabulous recirculation. With last grow, using 3/4 tubing, and the smallest pump I could, the drain-leveling flow on the feed side was just too slow (gravity based) for all 5 buckets to remain at a constant level. I knew I was going to have to change to pvc and larger diameter. This also allows a larger pump through the chiller too which is good.
As you can see in the pics, each bucket has a nice big air stone and is generating tons of bubbles. These are the big 4" cylindrical stones. I like em.
I added a carbon filter for the smell as well (bottom left in tent pics). Last grow it was just nutso strong and using ona gets really expensive at $30-$40 gal or whatever it was.
I'm now using a 230 gph pump on the return side with 3/4 hose. Tapering down to 3/4 prevents cavitation when being fed from the 1.5" pvc. I also added a ball valve to stop the flow if needed. I'll probably add a "y filter" at some point to trap sediment.
Also built a pvc frame around the perimeter of the tent. This will do two things. Prevent some of the tent collapse do to any negative air pressure if intake flow is a bit low, and this frame allows me to mount small fans (top left corner) and gives a point to attach string for netting to lay buds on when I am bending the hell out of these gals.
I switched to 1000w HPS for this grow to flower in. Should be interesting for sure. I just hope I can keep it cool enough. Bought the electronic ballast from JDL lightings ( a 420mag sponsor) and the bulb is a digilux HO digital bulb rated at 155,000 lumens.
The nutrients are running in the system now. Just waiting a few hours then I'll ph balance if needed (likely not), or thin if too high. With about 17 gals of water I added the following:
150ml BPN 2 part A
210ml BPN 2 part B
60ml BPN Bloom Booster
75ml Fox Farms Bush Doctor (will only run this in flower till first res change)
120ml AN B52
120ml Hygrozyme
35ml cal mag (about 1/2 dose)
PPM is sitting pretty at 930 or 1.86 e.c.
PH presently is 5.8 without use of ph up or down using ro water
Initially the water temp was 73f when I put it in and turned on the system with the chiller. In 90 mins time, using the larger pump, the water temp is a perfect 65f
I'll move the girls over either during the 1 hour lights on (they are under GLR) or in the morning and I'll start bending. I will probably take some clones as well and I'm really going to make an effort to either spread them way the hell out or shorten them through another topping (dont want to top now). But they are too damn tall because my closet is too skinny and I was too damn busy the last couple weeks to deal with it.
As I do those things I'll take some pics tomorrow so you'll know what I mean.
In the meantime, here's today's efforts:
