Interesting idea. I can get behind an artificial mulch, I've used panda film on mine a few times.

If it were me I'd fill them all the way with soil first, so the bottom edge of the foam pieces sit level with the rim of the container, then put the hairnets on. Those planters don't look very deep so you're losing out on valuable soil volume by not filling them

honestly I feel that with the depth. But last time I used these I ran into issues mid to late flower bc I feel I didn’t keep up with top dressing. Sooo I figured to leave enough room to top dress / amend I’d imagine weekly later on to keep the soil healthy. I would honestly like 20-30gals sips at some point..

Fair point. I follow the Growbox instructions to mound the soil up as high as possible but it does make top-dressing a bit of a pain if it's needed, especially watering it all in after applying it...

How many gal are the growboxes? I couldn’t imagine not having to top dress unless I had small plants in big containers. It’s a a tough balance I’m still figuring out but this is only my 2nd SIP run. Seen amazing results my first sip grow albeit up until mid flower then crawled to the finish line. Indoor is just such a different animal and takes more thought n care. I’m not exaggerating when I say I’ll be top dressing weekly. Them city pickers were filled packed with roots from some autos (Twenty20 Durban Sunrise & trizzlers, also freebie gnome automatics The Forge)
The ratio had to been off in that zone.

I think the Growbox is 1.5 cubic feet so like 11-12 gallons. I do one medium or two small-ish plants per box, usually clones with a couple weeks of veg time, but I think the key is reusing and amending the soil between rounds. It seems like my mix has gotten better each time and I've had to top-dress less or not at all.

That’s good to hear about amending. I’ll have go for that. I saved all my soil I pulled out of these. I spent a lot building it lol. U on well water?

I'm on city water with a whole-house filter. Last time I checked (few years ago) it was like 130 ppm and pH right around 7.

I started out using the KiS organics nutrient pack, their recommendation for re-amending used soil works out to about 1.5 - 2 cups per cubic foot of dry amendments, plus about 1/3 gallon each of compost and aeration. I've since switched to Espoma fertilizers, but basically use those amounts as a starting point, a bit more or less based on how the previous plants fared, plus some regular peat-based potting mix if it starts to get muddy. The last 3 rounds I haven't needed to top-dress at all after planting, it's literally topping off the res and watching grass grow...

So i flipped her but before doing that I made a cloner from a 5g bucket, nice thing had to share, I’ve used the hard plastic cups , am using coco with a bit of cal/mag , fill just above halfway and add some normal bag soil or a little dry fertilizer, I see growth on day five , after 14days they are ready to slide into THE Sip , I’ve attached pics of two clones that are 15days from cutting,
