Well, I guess technically speaking... Day 10 It's 3 am. I had to stay up to foliar feed with epsom salts at 1tbsp/gall with tap water to see if it's a magnesium deficiency. That's when my lights go out. Thank god I don't have to work in the morning. Here are some better pics :). Hopefully...

So I finally killed the lights to take a decent picture of the deficiency. It was not present 2 days ago for sure. Nothing has changed as far as PH or ppm much, so I don't really know what to say about it. I check PH and PPM daily, as well as topping off my rez with add back every few days. The...

Pics from today. Also look at other link for background info please.

The problem is showing in many leaves, not necessarily at the bottom or top of the plant.' I have a journal going on in another thread here. I was hoping I wouldn't have to post anything in this section :(. Here is the link -...

Day 10 OK, so I ran into my first problem, and I think I need some help with this one... If anyone out there is listening ;)... I have brown spots developing on leaves of all my plants. Most of the leaves affected are toward the middle of the plant (vertically speaking). I used a second...

Day 8 Stopped by today. All is well. Pics attached. At some point I want to kill the HPS lights to take a decent pic. Maybe tomorrow.

That is a pretty slick way of controlling temp. Are you using a CAP type computer for that? I don't know anything about soil, so I can't comment except that the plants look fantastic. Here are updated pics from.... Day 7

Wow, well I can certainly vouch for the system. At least for how well it works for the first 6 days, lol. I may have to look into just buying that one for my next grow. Good research!

I'd like to take this time to point out the only unforseen problem that has arrised... so far... as well as a solution to it. Diagram attached. The 105 gallon reservoir sits 1/3 full (always the optimist) all the time, except during the 30 minute nightly bucket drain. If the water is any...

Day 6 (veg) Alright, here are are pics from today. I added a picture of the roots. It's hard to tell due to all the yellow light, but the roots are pure whiteness. Probably due to the 1ml/gallon/day of 35% H2O2 added (every day). These babies are takin' off!

Bonus pic until I get over to take pictures at my RDWC. This is my standard Ebb and Grow 36 site bucket system right now. This one is not converted into RDWC. Pic is from this morning. I'll be taking pictures of my other room later today, so hang tight calicultivating.

Well, I'm sorry to say that the roots have barely even grown into the dwc system. I'll take a picture of one with the lid off to show you. These plants were transplanted from 4inch cubes, and there is still of layer of hydroton to get through before reaching the hot tub :). Pics incoming.

Day 5 of Vegging since transplant from 4 inch cubes. All is well. Pics attached. I think I like the way the plants grow better during veg with the GH 3-part, but Lucas formula is definitely more than adequate for veg. It's slower, but if you have a veg room, the difference in veg growth...

Well, everything is going well so far with the system, as in not even a minor issue. I took some pictures of my external RO rezevoir. I use it because putting a float valve in my main rez doesn't work because of the way this dwc works. So it is easier just to always have a extra couple dozen...

So went to go check everything out today. Looks like all is well. Got a bluelab guardian PH/EC meter all hooked up, and it measures a bit different from my Hanna stick. I attached a pic showing the flood/drain setting to accomplish this. ppm 880 ph 5.9 temp 69F Please, can someone please tell...

Any comments, concerns or questions along the way would be awesome. This project is a learning experience for me. If it works out well though, I'm sure the community would benefit as well :).

Plants appear to be taking the transplant into full strength lucas formula very well. Some of the 4 inch cubes are beginning to seriously dry out though. Tomorrow I'll see if the small layer of rocks under the cubes are wicking well enough to keep them alive until the roots hit the DWC. Pics...

Wanted to post this in case anyone was interested in a easy way (albeit expensive) to build a recirculating DWC. I'm going to journal the first grow using this system. The Ebb and Grow system in place has been used for 2 previous grows, but I decided to use this space to experiment with...
