they look all tucked in cozy and comfy like in their white linen beds. I see the manufactured caps are all plastic. I don't think my makeshift caps of landscape fabric are doing much because they could breath too much but that's ok. I got soil in fabric pots (breathable) with wicks sewn in so maybe that's not right either but whatever. Things grow pretty well anyhow.

Really goes to show how important watering is with organic,sips take care of that.My first organic attempt was in 5 g pots I think 5 plants not one of them turned out,droopy leaves no matter how little I watered.Now with the sips my soil moister meter says 9.9 every where in a 10g tote and plants are happy as hell.Go figure,over water just a tiny bit and all goes to hell in pots.

Sips are my future for sure,so easy and you can top water in some nutes to fix a N deficiency quickly.
Here's my Cali O in a 10g double stacked tote home made sip

I thought I was bad at watering. After I got the sips, I learned I was actually terrible :lol:
Since sips keep the soil so wet I wonder if bottom watering a pot would be better.Should work,it wicks it up just the same.Just gotta know how much/often.
I've switched to bottom watering my solo cups now too. I don't understand how I didn't kill everything before.

Have been looking at capillary mats - both a DIY method or there are some pretty cool seedling kits that I think will work well too.

I think y’all are really onto something.

Yeah I don’t keep plants in the solo cup for too long, because either I can’t get the right moisture level and or nutes run out. I do the 40% Peat 40% aeration 20% EWC. This time around I put a cup of coot’s on top of each. I can’t stand to see them look so bad and sad

Yeah I might have murdered a couple seedlings due to bad conditions. Gonna see what kind of miracles these sips can work. They have brought back a plant that almost died in my dwc. I broke the tap root off and it never could get its footing, just weren't enough roots getting nutes from the water. Enough to barely stay alive. It's looking great after a few days in the sip :mrgreen:

a few grows back before I started using the SIP's I was watering half gallon on top and half to the bottom, it would be sucked up within half hour if not sooner. I'm scratchin my head wondering why I stopped.

Folks using LED’s:

do y’all have cal-mag problems with SIP’s? If you do how do you fix it? I’m using coot’s soil recipe and last grow I didn’t have a problem with it, but I wasn’t using a SIP.

From what Ive read the bottom roots are the "water" roots and top ones are "feeder" so it makes sense that over watering the top isnt good and explains why bottom watering works well ,aka SIP.
No real proof but its believable.
Makes a lot of sense as far as the success of a sip, it can have plain fresh water, or nutrient rich soil. And of course, that nice layer of oxygen

I had a couple Dough-Lato's that seemed to want all the cal mag I could.givr them in flower. This go around I added some gypsum and Epsom into the soil when I mixed it.

If you need it asap i dont see a problem with using calmag in a spray bottle and misting the surface.Myself I added dolomite lime when I built the soil.You can also spray leaves with epsom if your getting yellow between veins.Ive even seen dolo lime tea bubbled for a few hours.

I think I should be fine. Coot’s mix had lots of Cal and I’ll be top dressing with homemade EWC castings. I have some root’s organic Cal-Mag top dress powder, thing that sucks about it is it’s really hydrophobic. Another thing is, is I top dress with malted barley and kashi which can bring the pH down.

Transplanted 48 hours ago and looking better. I do t have too much hope for the old leaves, but the new ones look great. I have a feeling it will take a 5-7 more days to adjust. There is already a larger “feeder” root coming out the top. I did put 2tbsn of Bio-Alive in a trench, I’m hoping that doesn’t upset the soil chemistry. The soil was already amended. For some reason I didn’t think it would come into play for another few weeks. Anyways we shall see what happens in the next few weeks. I think I’ll start a journal.

the gal isn’t looking to happy, but better.
