And the other sips.had a bunch of colas fall over. Doh! My bad should have had better trellises. Had lay down some plastic trellis and a bunch of wires to get everything back up. Continued with top dressing every week and some top water over it daily. They sure eat a lot. 1F6191EB-67B6-4350-83F7-2F2E07F9F54D.jpeg

Awesome information thank you, so 4-5ft tall
plants might need more room than a coco/perilite 60/40 mix? I thought one of the advantages of hydro is you can use smaller pots than soil to get same or bigger growth.

I would not be using soil in the octopot but coco/perilite 60/40 mix.

Thoughts?
What will you feed them in the 60/40 coco/perlite mix? I get the impression most of the SIPs in this thread use an organic soil or super soil of some kind, and have plain water in the res. A SIP with inert medium and nute water in the res is just a Hempy bucket, right?

Basically yeah except the octopots have a wider water base for cooling and oxygen purposes

Ok guys, noob question. In a sip, since your adding water to the res and roots grow down into the res, im guessing for drinking purposes (for lack of a better term), should that water be ph'd since it's not getting buffered by the soil and is being used by the roots that are in it?

Hey guys, quick question. If I want to water something into an earthbox from the top [i.e. compost tea, nutrient tea, etc.], I know I have to let the res go dry, but do I need to let the soil dry also? Seems like a stupid question, I know, but I'm asking anyway so I don't fuck anything up. Lol

My res stays full and I top water over my dry nutes almost daily,1 1/2 red solo cups worth with out worry of runoff.

I just did about 3%to soil volume watered in on an empty res. Should I fill the res now? Also, how long can I let the res sit dry? Once roots are in there, they'll dry up no?
Edit: I see, your res stays full.

Sure fill it,once roots get into the res I think keeping water in is good.
What sip do you have?

Everyday at lights on I top them up,one plant I have drinks it dry in one day (7 litres)so theirs probably a lot of roots in the res.Another is a slow gal takes only a litre or two a day.

I peeled off the 5g bag of my latest wick/sip and noticed it was more packed with roots on the upper half than the lower half. And the lower half was real moist. Maybe one wick instead of two next time?

The tomato sips outside, the deli cup caught up to the wick both are 64" and have been hard to manage they are so top heavy and both are loaded with plenty of ripening toms.
