After culling some vegging clones due to spider mites, I am back in the SIP game!

Doing a preservation run on a pack of M10/ Purest Indica from AKBB. I'll get the roots going into the bottom, fill the reservoirs, then flip!

I've had several great runs in my earthboxes with organic soil made with ProMix base, and the usual amendments. Never had a nute or pH issue. I was running a Piff (PCF Midnight Mass) and an Ace Panama/Bangi haze in 2 EBs side by side, same mix I used previously, just re-amended in both. Started same time, flipped same time. In 6 weeks after flip the PBH had huge colas, and the MM was just getting started. About a week ago, the MM seemed to stop growing and stopped drinking (7 weeks after flip, it was 5 feet tall and budding), then I noticed some wilting and discoloration. I assumed it was nutes, or possibly a pH issue/overwatering, but in hindsight the PBH looked healthy as can be in the same exact soil. A couple weeks ago I had done a final top dress with some homemade compost and castings plus BAS Build a Flower, to both earth boxes. I went on a short trip to help my sis post-Helene, (she had no power, tree on house, I took her coolers, ice, groceries, lanterns). When I got back after 2 days, the MM was DEAD. I mean the entire plant wilted bad and leaves crispy. Res had plenty water. Well, it turned out to be root aphids, and they had totally eaten the roots - the stalk pulled out like there was nothing holding it. I got the EB and plant out of there right away, trashed the plant and the soil outside. Here's the thing - the other EB has shown no signs of them dang critters, but I'm taking steps to make sure since I only have a couple weeks to go. Hope this helps somebody else. The PBH is looking fantastic, huge yielder, so not a total loss. Pretty sure the invasion vector was my homemade compost/castings, not sure why the PBH isn't infected.

Can anyone tell me if there is a formula for soil wick size to total volume? I made a 4 gallon sip with two 2" pvc pipe wicks and it seems a little to moist all the way to the top. Its a trial for now just growing kale to test it.

I don’t have a hard formula. For 5 gallon and under a lot of people use something like this https://amzn.to/3ZRzNJD wicking rope. For my 17 gallon sips I have 2 4” net pots as wicks.

Question for the brain trust I am running some autos in earthboxes... how do you all tell when is a good time to start adding water the bottom rez? I am just top watering atm as they just got transplanted to there. No flowering or anything showing yet so fingers crossed I can get them nice and large before they start to bud up. Thanks!

I wait to see growth. Once I see the plant has acclimated and growing, I add water to the res.

I fill the res right from the start, why not?
