Holy shit, it's already August. Can ya believe it? I sure can't.
I'll be firing the RDWC back up in a few weeks after sitting idle since the last harvest many moons ago. I'm guessing by the middle of next month I should be able to keep water temps in check without a chiller. Or at least close enough for the first couple weeks.
Honestly I could probably do it now. The two reservoirs on my other tents (Recirc dutch buckets, cycle every 3 hours for 30 minutes) hasn't been above 73 at all this summer. Thanks to sitting on a concrete basement floor, I suspect. Either way, a 6gal and 20gal, so significantly less volume and a little more fickle. If they've been good, well, I probably could have made it work. Of course another reason for shutting that one down was to knock off the power it was using to offset the house AC running for the summer. Thankfully, with everything else running, the leccy has only been running about $100 over what it would have been without running any of it.
Some may recall that: a) I like to tinker, and b) I had a list of changes I was looking to make:
You can
read the descriptions for each, from last spring, in the full post.
I'll cover what has/hasn't/will be/might be happening over the next few weeks.
Primary Pump
Not bothering with it. 400gph is enough, and just gentle enough per bucket to keep the roots from getting sucked down the drain.
Bucket Height
So this has bothered me from the start. Specifically from the "hump" in the return line to get up and over the duct to get out of the tent.
Problem solved. How, you ask? Well, I mentioned this to
@Stltoed and
@The Phantom a week or two ago, with a crude drawering, and well, here's a little better info. It may not make sense to some when looking at it. But don't let my lack of drawering skills get the best of ya. It's right in my head, so if the drawing isn't perfect, I couldn't care less.
For reference in the next part of the discussion:
Now, this isn't to scale, and just for showing the concept. This drawing isn't a fucking blueprint, just a general picture to see the concept.
I thought this up a bit ago, and what got me thinking were reef tanks I used to keep. Specifically the
overflow design to get to the sump.
I thought it though, then did some digging. Not many people out there admitting to doing this, but there are some out there.
WTF did ya smoke, MV??? Well, whatever it was (night queen/gdp salet) it was fire.
What we have here is the bucket in the tent that connects to the res. The one causing all the drama with the hump flow. Well say no more. Say no more!
I will be adding 3 of the 2" spintight bulkheads to this bucket. 2 will be on the main drain side, one slightly higher than the other. The third one will be on the opposite side, and higher than the other two for an absolute emergency overflow.
I'll go over each view above.
From the top view, you see two on the left. Each will have a tee fitting inside, with the branch side horizontal. Effectively the tee is on its side. To that branch I'll hook a 90* elbow and point it up. This will add yet another "emergency overflow" option. Probably more than I need, but using 2" bulkheads makes me a tick nervous, so I'll go overboard to save having to drain the tent. lol
On the right, you see the third, highest level drain. This is also the side where the supply will come in.
With this bucket, being the water will be going out at the top, the supply will need to come in, down and out near the bottom. I plan to split the flow and get things mixing a bit. One, to keep from developing a thermocline layer; two, to hopefully trick the roots from following the gentle flow out of the bucket. Will that work? Fuck if I know, but it sounds good in theory.
But this should give a decent visual of how the two main drains will be offset just a tick, and one a hair higher. (This also works out well as it will give this now gravity powered drain a slight angle to flow back to the res.
The bulkheads will be 2", but all the return pipe will be 3". I'll add a 2"-3" coupler right at the bulkhead. The 3" will go
straight out of the tent, with NO HUMP! Yay!
This keeps the buckets on the floor (good, because the tent sits on a concrete basement floor), takes the hump out, and these drains should be able to eat 5x the flow I'll be pushing. I think we're alright here. If not, better luck next time. Either way, it's happening.
Oh yeah, before I forget... I did need a new bucket. Kinda funny how a 3" hole at the bottom of the side can kinda wreck the above design real quick.
I picked up a Current Culture 13gal undrilled multi-mod. It was twice what an EZ Stor is, but has a few updated features. Current Culture used to use the EZ Stor buckets, but made their own version. The updates are a slightly raised floor for thermal cooling (cold water, cold floor, the tiny void between the bottom of the bucket floor and the concrete should do well), and also a
full drain well.
Drain Line(s)
I'll be using 1/2" bulkheads (with a barb on the outside) towards the bottom of each bucket. The new bucket already has the hole, but I'll add it to the other 3. Hose to the barb, connect them all together, put a valve on it, then a pump. This will get all but about an inch of water out of all the buckets. No opening squat, and dealing with trying to be easy because you've got a 16sqft canopy roped up just above your head where you are trying to see inside the bucket. lol
I wasn't keen on having another bulkhead below the waterline, but I also use these for making a water level indicator on the reservoirs and they're solid. Of course I have emergency supplies just in case they are needed.
Supply Line
The supply line will be remaining at 3/4", but I will be adding a tee on the inside to split the incoming water into two waterfalls vice one, thus contributing to oxygenating the water. I wanted to do spray bars, but really don't want the extra head height on the pump from that. Big, open, natural flow. That's what we're going for.
Lighting
I haven't decided yet, but for now I'm going to just roll with the hard timer for power and the controller will just dial in the output. I'd skip the controller all together, but it has a little finer control than the 40%/60%/80%/100% settings with the knob on-board the fixture. I plan to run it at a peak of about 500-550 watts on the next run. A tick less than the 680 it's capable of. However, it's also going to be running 18/6 from start to finish.
Wait, wut?????
Keep reading, it'll hit ya.
Upgrade Top Off Tank
This is easy. Move the bulkhead (which just happens to be the same one I'll be using on the buckets) to a new tote, and maybe shorten my stand a tick. $10 at lowes and we're good there. I need to pick up another 17gal for my 3x3 tents new res (huh?) as well, so no biggie. I'll probably grab a couple extra since they're handy as hell anyway.
Oscillating Fans
As the stupid vivosun's die off, I'm replacing them with a holmes lil blizzard on a microphone stand tablet holder. Got the idea from a thread here, I may have mentioned it before. Either way, that's what's up. I've got 2 of them running now, and they are excellent.
Nutrients
Here we go. I'm off the MC this summer. Even with a fresh bag of the no balls v3 sitting here. Several reasons are behind this, but I went back to the GH Trio. I know it well, but what I'm wanting to do here is work with my water. Yes, I'm using RO water. However, the 75gpd, 2-stage filter I'm using now just can't get 100% of all the damn dissolved limestone out of the water. Limestone making pH go up, and well, that's what I keep seeing. I'm also waiting to see if I have an issue about 3-4 weeks into flower where a calmag issue shows up like it has with MC. Whether that's a lockout or deficiency, no idea. But once you get into flower and behind on calmag, you're staying behind. Gotta get that built up early, it seems. So far I've been doing that with the girls currently running, and it's working. I'm just starting week 3 from flip on the 3x3, so we'll know shortly. So far though, that Deluxe Sugar Cane from IHG is lookin hawt. I'd hit it (and you're damn right I will once she's done, lol.)
More on some of the above in a second with the details of the upcoming run.
Above was my plan for the next RDWC run.
Keyword: was
I'm still going to run those, but not quite yet. I'm going to fire up the RDWC earlier than I planned, Enough so, that I'm going to squeeze in a run of autos before Christmas, and still get another photo run in before I turn it down for next summer.
Autos? WTF? This ain't the damn Lab, you big dummy!
No, no it's not. But I've wanted to see autos blow up (in a good way) in this rig since I put it together. I didn't think it was going to happen so soon, but take what ya can, when ya can.
That run above is actually going to be around Santa time, so happy birthday Jesus, let's grow some natural fun, eh? (See, I can speak Canadian too.
)
That run is going to be a little different, but not sure what yet. So many choices, so little time. I do know that Deluxe Sugar Cane is out, since it's already running (she's the one starting week 3 flower.)
I'm also going to replace one of these with Night Queen. The auto from the spring lab run is pure fire. OMG it's an awesome strain. I like it so much, that I wasn't even done with the first taster bowl of her right after drying and I was buying the photo version. This strain is just a beautiful expression of the genetics. Yield wasn't stellar, but you'll be so medicated you just won't care. lol
I have a bunch of other stuff too, but not sure if I'll run another something or other or not. To be honest, I probably won't make up my mind until I'm a day or so out from dropping seeds.
For the nutes on this auto run, I'm tempted to give MC one last shot. However, I'll be tweaking my normal just a bit. First change, calmag. 3ml/gal for week 1, and then 5ml/gal from there on. Second change will be when I flip into flower. I'm going to run 4.5 to 5 grams per gallon, or there about, with a little bit of bud explosion on top. Like 1/2g per gallon. Then I'll watch and see. I'm just not convinced that the level of N in MC isn't just a tick much for flower.
Whether I do this or not, I don't know. I have enough trio to get me through, but we'll see. I'm still tempted by Jack's, but not sure I want to commit to like 8 runs on a whim. Not that they're bad, but who knows if it will work with what I have going on, and if I buy multiple small bags I'll pay about as much as I would to just go bulk. Not sure yet, still thinking it through.
So that's been the summer of nothing for the RDWC. However, things are just gettin started.
