SIP thread -- (Sub-Irrigated Planter)

Roots will cruise right through landscape fabric I bought the cheapest of the fabrics on purpose, it looks/feels almost like fiberglass mat. The more expensive fabric you get, the tighter the weave.

A little update with my gal that I fed salt food too. Just before Christmas I noticed some rust spots and the lighter green colour. I gave the first dose on top about 400 ppm. A few days later thought what the hell let’s put some in the res. Around 600 ppm. The rust spots seamed to stop and got a little tip burn. I did one more feed in the res a week later so that’s around Dec 28 ish. Here she is now ,leaves have dried and curled up a bit. Fall colours are getting dominant. She’s at day 62. I think I fed one too many times lol.

How did your rez smell after putting nutes in? You fill it every few days? I tried LAB in the rez and it gets funky

My soil is a ph of 7, tap water ph of 7.7. I’m currently using ph down to get the reservoir around 6.2. Am I wasting my time using ph down?

What kind of ph down are you using? I run similar and noticing now my ph is rising after a few runs.

Phosphoric acid. What is yours starting from and then drifting to?

My tap is 7.2 ish,Ive gone 3 runs and never worried about it.Now because my water and all the top dressing its climbing.I only have drops now, my ph pen is dead.Its fairly green so around 7 is my guess.
Ill be adding some plain peat and home made EWC for the next run to hopefully balance it out.

Didn't affect smell.

Chopped one of the plants in the growboxes. You may not like it, but this is what peak performance looks like...

Despite looking like shit, she did not lose a single leaf, which is a personal best for me
Her twin is still ripening up in the back for a bit. The dense and chaotic bud structure of this pheno makes it susceptible to mold, so I probably won't let it go too much longer.

Here's the other box. This one turns a real dark purple throughout at the end

Happy SIPing y'all!

Looking good , should smoke well

I talked with Thomas from High Alpine Genetics, he makes columns of fertilizer on the outside of the pot. He waters only through the grow. He uses a cup of biolive per 5 gal of soil. His columns of fertilizer get past a problem in using sips. Top dressing requires top watering if the top dries out to activate the fertilizer. And in my case I use sand to cap the soil to eliminate fungus knats so it’s almost always dry. By the fertilizer being vertical in the soil column it’s always moist and available. That’s brilliant. Thanks Thomas!

I did something like that last run. I had ran out of cooked soil so I just added some Gaia to promix. Then added a layer of Gaia bloom in the bottom 3” of soil.
This round I’m thinking of adding extra dry to the wick.

Maybe some of those Jobe's fertilizer spikes would also work...? That's a very interesting idea

How did it work out like that?

The concern I have withputting it in the wick or the bottom is the water moves upwards always bringing nutrients with it as it passes, with it being in columns on the side it stays in the sides so the plant can access with lateral roots as needed

I was thinking that too, like @Richard Drysift does. I need to see howfar down the moisture level is to get the spike in the moist zone. I see that as an easier option.

The other benefit of adding columns of fertilizer or spikes on the side is when you transplant the fertilizer is located on the edges so it doesn’t cause nute burn. The plant can grow into the high fertilizer zone

Yes it worked fine. This was just plain promix hp. Mixed with Gaia and planted no cook time. I still top dressed and all was good. Plant wasn’t that big so that helps.

Water passes up wards in all areas. My dirt is all soaked top to bottom every square inch. Putting columns of food may burn a little when roots hit it. I’d prefer to have spread out evenly. Now plant size and dirt volume play a huge part.
I know 10 gallons is just on the edge of not enough. Roots fill it up.

Your right water passes upwards, not sideways, which may benefit the columns/spike concept, keeping it as a reserve. Spreading out evenly is what I’ve been doing but in a 5 gal but it runs out in 30 days. If I make it any hotter it’ll burn the plants. Needs some testing to figure this out.

Yup I find the same,5 gallons of dirt last 1 month.Really need 15-20G.
