T Dub’s Durban Poison Winter Garden

[KGB]

Hey KGB, yes….all feeding is done through the wicks from the reservoir. No top feeding is needed or recommended because of the salt buildup at the root zone. It keeps the bottom 1/3 of the pot damp with nutrient solution. It’s really a slick concept except for the required 1-2 flushes per grow. My memory isn’t that good, but I believe I only needed to flush if using coco. When I used Ocean Forest soil, I dont recall needing anywhere near as many nutrients so I had a lot less salt buildup. There’s plenty of nutes in ocean forest already….at least enough to get through veg.

I’m still intrigued by your earth box….might look at that for next winter grow if they look like two would fit in a 2x4.

In a 2x4 how many plants? In all honesty the earthbox can theoretically do four in one box as long as you stay on the water.

That’s good to know……I’m only thinking of growing two plants with a scrog net.

I do two plants in each of mine and they seriously make trees if you don’t train them. You should see my root systems

Another cool thing about them is the salt builds up in one area that you scoop out and throw way then the majority of the soil is reusable

I'm curious and need to ask....

Salts buildup. I'd like to see a pic of this exact issue. I can see it probably looking much like any other deficiency only hard to detect. It's not on most deficiency charts.

I ask because I don't water to run off and I don't flush. I've done it this way for a few runs and had no issues at all. To add my ash is grey and not harsh.

So what exactly are you seeing with this buildup? Is it the wick pots that cause this or maybe you see it more in wick systems?

At one point I was concerned with run off and salts but I've found peace in not worrying so much..lol

Hmmmm…..I’m trying to find photos and I may not have documented my first coco/automatic feeder grow. It looks like the start of nutrient burn with crunchy yellow/brown leaves when it happens. It happened once and I’ve always flushed mid-grow ever since. Everything I read about growing in coco emphasized the importance of runoff and the flushing out of salts. When I did do a flush on a previous grow, it was not uncommon to have runoff water with a high ppm content over 4,000 by week 10+.

I’m intrigued by your experience. I’m very tempted to switch to Promix HP next year. I wonder if Jacks also has less residual salts than my three part Flora series. Don’t know……but you and your plants are a great example of the potential with promix and jacks.

I know when I flushed a previous grow (Godfather OG) the initial runoff water had an EC content of 4,000 ppm.

Let me keep looking for a picture of my crunchy leaves.

Awesome, and thanks for that info.

I'd forgotten you use coco. Is that not more prone to salt buildup anyways? Maybe it's slightly different vin peat.

I have no answers for peat n jacks. I don't question it. I just watch it work. Sometimes wish I understood the workings of it all but I'm an old dog with no desire to chase the ball..lol.

4000ppm..lol. I'm afraid to check mine. I've not touched that meter in almost a year.

Just saying this because you are considering an EarthBox. The makers of the EarthBox discovered that the strip of 7-7-7 fertilizer had salt buildup. Since the plants get the majority of their nutrients from that strip they recommend digging the strip out and with it the salt material around it. Then the soil left is reusable.

Since I do put a tablespoon of grow dots in a pattern there will be minor salts there but nothing to worry about.
