SIP thread -- (Sub-Irrigated Planter)

[weedstoner420]

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?

Im sending 7.2 ph water to all my sips.There all drinking a lot more now so bare roots must be sitting in this water.I run right from the tap so chlorine included.

I wonder, if I could get a sample from the res thats 24 hrs old, if the ph changed?

Do you pH it to that, or is that your tap ph?

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.

Pending on sip I guess,I have 10g hdx totes.Also their root bound.

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?

How do you keep yours full? Is it automated?

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.

I do notice in my 10g sips that if I plant a bigger girl, 2mo veg she takes off in about a weeks time after planting ,roots hit the res(1 wick) then flip and wow.If I plant a smaller 1 mo veg she puts roots out on the top,doesn't take off during stretch.
My next round Ill veg longer until I get water roots..
