Hey guys, a quick question. In regards to DWC/RDWC So if you start with a certain amount of PH 7 water and use some acid to drop it to 5.8, would evaporation over several days cause a slight PH drift down? The evaporating would effectively concentrate the acid since there is a less amount of...

Since your using RO that pretty much eliminates all possibility of any scale/mineral buildup. If you started with really clean water and your buckets and lines had been sterilized......I have never run that way but it makes sense that very little maintenance would be required, Maybe if you added...

3,000 dollars for the 900w one.

I will have to check that one out!

Yeah, I went around and around about whether or not to buy an AC Infinity Fan this grow. I decided this would work but next grow I am def getting an axial/mixed flow fan. My buddy has a hyperfan and man, is that thing quiet. Thanks for the tip.

Headband OG has always been my favorite. Now I get to grow it.

The insulated duct made a HUGE difference in sound. I am running mesh until it starts to stink, and then I will slap the carbon filter on it.

Said air manifold. It is 1" PVC so I plugged it on one end, and put a 3/4 barb on the other. I plugged 1 of the outlets.

Massive air powered by the venerable ET-100 and 10 Sweetwater airstones. ( 2 per bucket) I used two stones because last year my roots had engulfed my single airstone. I had to cut it out of the root ball. I have a 3/4" line running from the pump to my hot-tub pvc air manifold. 3/8 lines from...

I just soaked the seeds same as before. Overnight and then threw them into rapid rooters. They popped the next day. The only way I know how to do it lol.

Here we go again. System took a weekend to get back up and running. I had folded up the tent and put everything into totes last year so I could use my garage for other things.

I started a new grow journal for my next grow. Here is what the system looks like this time. With a few small modifications!

Yellow leafs...spots...purple stems... Looks a Potassium issue since its showing on older growth. Whoever said calcium was close, but Cal is mobile and will stripe/spot your newest growth first IIRC.

No, it is a thermoelectric chiller that pumps water through the cold side of a peltier plate. That might be ok for like 5 gallons, but I would seriously question how long that will last. Amazon and Ebay are rife with those china models. Drop the 350 on a decent chiller. When you harvest that 350...

Yeah I know what you mean. That is why I got the narrow range strips. They allow for a better color match vs broad range since they don't have like 30 colors for 0-13. We only are concerned with 4-7 anyway.

I cut a small flap in the lid so I could bring the hose out, but not have dust and stuff get in there.

I built this trash can to mix my nutes in. It rides on a furniture dolly and has a pump at the bottom. Before I got to work I dump what I think I need in there and let her mix. The pump is attached to a hose that I take out and use to fill my res. Beats the 5 gallon jug. If your using something...

I have two of those combo meters. I never noticed that moving the PH pen around messes with the readings. (The TDS meter is a different story, try putting it next to an airstone) Leads me to think you got something wonky going on. Do you have strips you can use to double check? I got some...

If it dries it dies lol. That might be true sometimes but I bought both my combo meters out of a dirty ass bin in some dudes garage, both probes dried and covered in shit with no caps. Cleaned them up and both served me very well for the remainder of my grow. The glass you use for a...

Whoever mentioned permeate pump +1. I have heard a lot of good things about those, besides the ticking.
