SIP thread -- (Sub-Irrigated Planter)

The fast growth is causing a bit of a problem getting air where I need it. I've cut more out of the bottom of these plants than the ones planted in the 7 gal bags have growing on them. And the stretch is more. Leaves twice the size of my hand. I had to buy a 50 pint dehumidifier as the 25 was running too long. I use it in the room outside. Next time I'll either grow half the plants or smaller sips. 4 weeks of veg with 4 plants would easily fill a 5x5 net. Crazy

I noticed some stinky anaerobic soil in my one sip,it was the bigger WW plant that I showed last.Watered too much towards the end.My other plant is still going,FFC Ive stopped watering for a week now.Waiting for it to dry out.Its about 20g of soil.
Stop sniffing the soil. :p

None of my other sips had that smell. Gotta watch out towards the end not to fill the res so often. This sip also has two 5” wicks. So that probably didn’t help.

I'm seeing roots through the fill hole on my sips. Is this normal? Do you guys reuse your soil or replant with new.
I've not seen any in mine, but I think it may be because the fill tube goes almost to the bottom.

I'm running mine no till, on its 2nd cycle. Some other guys recycle, some use new. It depends on what you're going for.

My res is full of roots, but ive got air stones in there.
May be a good idea. I was going to go organic soil aka build a soil etc. but after watching tons of videos of earth boxes including I guess the older gentleman who either marketed or came up with the idea. So I'm trying the fertilizer strip method. The 2 per sip it looks like are going to run out of fertilizer. The one per sip looks ok. 3 cups of fertilizer for all sips. Are you using organic soil?

i use fertilizer Trenches (strips) on my sip grows, the work great, the plant sends roots into the res, and roots into the regular soil and then i get feeder roots that go into the trenches
