Which would produce more DO in a DWC?

So it was bud rot? I dont think its a root issue if its only occuring directly beneath the light. more likely a temp/vpd issue. Do you have an IR temp gun? It might be worth checking the differences in temp between plants and making your screen a V or bowl shape to more equalize light distances.

Got an IR gun, and the temps were always between 75 and 79. The other colas are fine, so who knows. They don't smell rotten, more of a cut grass kind of smell. It's almost like they finished early and started to go bad. Thankfully it's isolated

Got about a week left on the remaining plants (2 x White Widow, 1 x Gorilla Cookies).

My killer, no-chiller solution...

I refuse to get a chiller, but determined to keep my water temps down. Last few hydro grows I used frozen jugs to keep temps in check, and it worked great. However, it's kind of a pain. I also had a small fan blowing across the surface, which also helped keep temps down via, evaporative cooling.

What I'm trying now is using the room's vent, and ducting to route the cool air to the water. I keep my house blower on all the time because it filters allergens in the house. So, there's always cool air blowing on the water.

So far it's working really well! Temps are hovering around 67f/19c!

Got lots of hefty colas, and very little larf! Way better than last grow!

This is the Girl Scout Crack tally. The weight of these buds and colas is impressive! But, I had a couple tops thatt were rotting, even though there's nothing falling apart. It just smells funky. I separated one of the brown tops to see if I could salvage the lower half. Should i just toss them (the good parts), or will they be fine?

Been running since last night with no leaks! Didn't start off that way though.

First, I wrapped the threads with Teflon (for extra protection), and used a single washer on each bulkhead. I had a couple stubborn drips that I couldn't get to stop, no matter how tight I got it. So I drained the system for adjustments.

Next, After removing all the Teflon tape, I decided to use two washers/bulkhead to thicken up the wall a little. Both the washers for each bulkhead were on the male side (using a washer on the female side does absolutely nothing). I had better luck this time, but still had a couple slow drips I couldn't stop. I noticed that the drips were coming from in between the washers. So I drained it again.

Lastly, I used a single washer and no Teflon. Worked perfectly! Well, almost perfectly. One of them has a very slow leak that just seems to leave the washer a little moist. It really doesn't even drip. So I don't know if I'm just going to live with it, or if I'm going to go the next step, which would be using some epoxy or sealant on each. I may even do that just for assurance. who knows what may pop up later.

Lots of bubbles!

Manifolds

Controller reservoir fits perfectly here! Didn't even have to modify the pump manifold going from the bucket to the tote! Luckily they were about the same height.

All my valves are still very easy to get to.

Got pretty good pressure for my waterfall now. I might go up to a larger pump at some point. I've got a lot more water to circulate now. With the buckets I was around 25 gallons. Now I'm at about 75 gallons, which is way better, but I'm probably going to want to account for that. I've got my formula around somewhere, but it's pretty easy to figure out. I've tripled my water, so I triple the gph. 1200 gph sounds right.

Do you have any leaking issues with your pvc fittings since you sealed them with aquarium sealant as I'm downsizing and doing a 2 tote setup with 27gal however I'm going with the lowes brand not the cheap ass home depot trash ones they have as they are 1/2 as thick as lowes....also I have read cvpvc grey is best for them sealing together as they are tapered and the pvc is not which maybe why your having leaking issues or that the buckets are too thin and the lowes would be a better bet if you had issues...I'm thinkn about doing the pvc and gasket fittings over bulkheads but not sure if they seal and will be worth it and not have 100gal in my basement...also if you would do it again would you change your return line size...and what about using 3way tees instead 90 elbows for easier cleaning? And pvc return line over the 3/4 hose? Thanks

Tees are something I overlooked

Hey everyone, thought I'd check in, and go over why noobs should stay away from aggressive strains when growing indoors.

I thought I'd grow another batch of Super Silver Haze, and just like the first batch I grew years ago, it's been quite a challenge keeping them from kissing the light. Just for reference, the two colas in my signature are from my first SSH grow.

In nature, these are trees. They'll grow 25', easily, so growing them inside takes a lot of attention, and experience in high stress training. In the pics below, they are 4' tall, and the tops are about 12" from the glass of my EH 1k hps I'm a few weeks into flower, and have had to super crop almost every other day! But they won't slow down LOL! I've seen top branches grow 4" on some days! I'm thinking the stretch is almost over, or at least I hope. SSH go for 16 weeks, so I still have a ways to go. i'm going to have so many top buds, but some right under the light might get bleached.

So noobs, you'll want to stay away from aggressive strains like this

My temps hover at 80, at the tops. And, I'm still able to keep my water temps at 66 to 69, with no effort, and with no chiller!

This is the view from my side door LOL!! Doesn't leave much room to work anymore, but I think they've stopped stretching.

I get cool air to my res a little differently in the winter, since the floor vent would be blowing out warm air. Instead of using the room's floor duct, I use the fan that brings fresh air into the room. In the summer, I use the floor vent, because the air coming out is around 62 degrees. Much cooler than the house temp in the summer (73 degrees). My house in the winter is 68 degrees.

So in the summer, the house ac air blowing on the surface of the water is cooler, but the room is warmer (80), so the res ends up being 67 to 69. In the winter, the air blowing across the water is 68 degrees (really 69 because the fan and tent add a little heat), but the room is 75 degrees. Again, the water ends up being between 66 and 69 degrees.

My 4" fan that brings air through the sealed closet, via a vent/register in the hallway.




The fan's exhaust runs behind the tent, and into the res.




Air intake, on the other side of the sealed closet




And as you can see, I'm right where I should be, using far less than a chiller. Granted, this works for my environment, and wouldn't work for everyone, but I imagine my house temps are fairly common.

hey JSB, haven't seen you around these parts in a bit. how goes it?

Everything's good.

Been getting back into recording and mixing. I had given it a break for a few years, but got the itch to pick up the guitar and bass, and start playing again
