yup, i just didnt want any popcorn or larf this grow, i have jars of that stuff,, so only going for top colas, plus it kept them compact and i have plenty of room for stretch, ,, its been fun doing mainlining, this has to be the most fun i have ever had with a grow, zero issues, Pushing 275 watts from 6 cobs, I have a max of 375 watts of cob power,, dont know if I will be able to dail it all the way up or not,, we shall see
Is this your first Exp. with Main lining? If you have done it before how did you like it? easy to break those steams when they are in the initial tie down stage? I have been looking at it for a while now and think i could work great with SIPS. Gets rid of the "sucker" branches and get you some huge buds.

Then you overfertilized. You can flush by letting the res dry out and watering thru the top to drip into the res and siphon the water out of the res daily and water the top daily for a week or so if you fertilize that much. Use an airstone so a lot of the roots are in the res. Then you can use more of a hydro system and use just water at the end of the grow. Most of the water will be coming from the res. Where there is a will there is a way it's all about understanding the physics and options.

I don't know anyone who uses a soilless medium in a sip , it's possible, but why bother pHing water and measuring ppm and tdds that defeats the whole reason for a sip

But chemicals are not used in sips we use organic and no till soil so there is nothing to flush , how can you have a chemical taste when chemicals were not used?
I think I got the soil mix idea from you, it's ffof marine cuisine and happy frog dry ferts mixed in to the soil. I'm guessing I'm tasting left over nitrogen because the leaves don't yellow much

The whole reason YOU use sips. They are pretty versatile. They can be used any way you can use them if you just want to be able to leave for an extended period. You don't even have to use the reservior unless you are leaving town, You can use them just like a 5 gal bucket and never fill the res if you want week to week feeding control for higher yields.

sounds like a good soil mix,, i wonder if the plants needed to go longer?,,, who knows, glad you made it to harvest

i was wondering what you thought would happen to my water roots if i let the res dry out as you recomend,, it would probably destroy all my hydro roots ,, i kinda wantIMG_1718.JPG to keep the hydro growth, i think letting the res run dry would certainly kill all my water roots ??

Ya, depending if they are growing thru the mesh or all coming out of the columns. If they are touching water they should be able to keep the part in the air alive. If they are thru the column and just lay on the bottom they should be good if you let it get down to 1/4" or less. Not really sure though. Mine poked thru the substrate and grew an inch into the air when the res was closer to full but they died off, never touching water, when the res dropped to 1/4" water. It was more humid with the smaller air gap and dried up with the larger volume of air and less surface area of water in proportion and the tips died. The column roots were good when there was just a layer on the bottom of hte res of water.

these types of sips do not use mesh,,, the earth box and the grow box,, no mesh

these types of sips are designed to have lots and lots of water roots,, the earth box , the grow box and the octopots are hydro/soil hybrids, we count on water roots, and they grow big and lush just like a DWC,, i count on my water roots being alive and healthy and providing hydroponic type growth without the hydro work,,
my roots are alive and lush and filling the res by the thousands,, and without air strone,
if i were to let the res run out of water,, or water from the top my plants would suffer really bad
i think we are using 2 differant types of sips

for instance take a look at the octopot sip,,, big time water roots,, without airstones,, and lush and alive in the res,, letting the res run dry would be very detrimental to these plants,, Octopot Grow Systems   Outgrow Your Pot .png

Perforated, mesh whatever. I use the same box. And i've top watered while htere was water in the res. your roots must not have been spread enough or you are using a top to keep it moist up to the top of the soil.

Not if there is enough moisture or humidity in the res. running totally dry and letting the media dry would be detrimental. Roots can stay alive in air with the right amount of humidity. It'd be risky and i wouldn't do it if that's what your goal is. Everyone has different goals.

Can you elaborate on what you are referring to here? I am using a DIY sip with a fabric pot and no cover over it, I never need to top water, and my res is full of roots... not sure what your "roots must not have been spread enough" or the reference to using a cover ("top"?) to keep it moist -- what impact do you think those things would have?
