Things are perking along nicely. I’m adding 2-3 solo cups of water a day. I have the plastic lids on is there any concern of not enough air? I don’t think so but thought I’d ask. Also what about top dressing. I plan on adding some home made ewc do I just mix it in with the soil and leave it? Im kinda paranoid of watering it in and getting runoff in the res. Same goes for dry amendments like Gaia flower. Just mix it in with the ewc and leave it.
thanks.

yes covering the top soil with a lid or plastic is actually preferable in most cases, it keeps the top layers moist instead of allowig them to dry out too much,, most everything i have read says its not good to top water a sip because it dissrupts the wicking cycle, but part of me feels a little bit cant hurt to bad?,, i know on the octopot sip web page they actually do add nutes to thier res and so did another grower on rollitup who used the octopots his name is captian morgan ,, i believe,, but they dont use salts type nutes its organics of some sort,, i never paid to much attention to it because i mix everything in my soil at te start of the grow and do water only the whole ride,, maybe some of the other people following this thread have more usuful information bout the teas and nutes,, @Humanrob might also have some ideas?,

Not a curled leaf in sight.Looks great!
thanks some leaves on the front curl down, but its because the doors squash them down when i close them,,this is the best healthy grow i have ever done,, i am really liking the soil mix i put together at the start

Day 25, this is pretty much a no-touch grow besides two rounds of tea quickly poured on top.

So far the no-trellis is working and I like that I can just push everything out of the way to pour tea on the surface of each Earth Box without too much trouble. That was always a pain in the ass before to duck under the wire.

I just take a 6 gallon bucket of water out and dump it in the rez each day and that is it. Easy!

When it warms up I can probably just switch that out to a garden hose.
So there is someone poring tea on top,Any tips.I was wondering about top dressing.thx

I’ve already been seeing people have great results with top dressing their earthboxes!
in this thread? or a differant thread,,, i dont recall seeing any here,, and if a person is not top watering, , how would those top dressings get broken down and filtered into the lower soil>? mostly because watering from the top on an earthbox disrupts the wicking action and floods the soil

The advantage of earth boxes is their ability to hold clean water in the reservoir on the bottom so the roots always have access to clean water this is what allows for top dressing. You will get little feeder routes that will come all the way up to the top of the soil because you have a cover on the earth box. These feeder roots Will have access to the top dressing when they need it. This is why it is also hard to overdo top dressing with a Earth boxes because your plants always have access to pure clean water so they can self regulate themselves easier. *You do not have to water top dressing from the top in earthboxes*

I’ll post a link to the thread when I find it. I think it may have been on autoflower.net

I was watching a video today on youtube's Future Cannabis Project channel and there was a guy explaining soil horizons in raised beds and pots. It seems pretty interesting and sounds like it could perform like a SIP because of the wicking action it provides. Has anyone messed with this idea before?

Quote from youtube:
The bottom layer is the E (eluvial) horizon, sand and gravel, which allows water to pass through but not organic matter. The next layer up is the A horizon, which contains mostly clay and silt and a little sand from the E horizon and some of the organic matter from the final layer (the top layer), which is the O (organic) horizon. The O horizon is an airy mixture of mulch, worm castings and other organic material.

@Tim Fox you were asking about a thread with earthboxes. Here’s a great grow journal using earthboxes, top dressings, and teas. Great info & I’m sure if you have any questions he would be glad to help out :bigjoint:

Watching this now... our wicking system seems to emulate part of this... but, he talks a ton about the fact that most growers are missing the sand silt and clay that has a lot of beneficial organisms in it... I wonder how we could emulate that in a sip..... could the wick by constructed from a mixture of say... pit or peat moss, sand silt and clay? I wonder....what do you all think?
