I always dive head first into shallow water, it makes for more exciting times.
Yea, I hear ya. It’s just that I have never used a sip, I could try an Earthbox and a Growbox and see which one I like better. Eventually I want to settle on one, fill my room with like 6 of them and use 4 outside for veggies.

Well lads,

My homemade fabric sips are working away, when filling the res yesterday i noticed some mould growing on the diy water level float i had made from a skewer and polystyrene. Any ideas why it grew and how to prevent it coming back?

maybe try some plastic chopsticks instead of wood.

I am getting really close to needing some SIPs. I have 6 Space Monkeys ready to chop next week. After that, I have 6 more that I will be taking out of the RDWC and putting into 5 gallon DWC buckets, allowing me to dismantle the RDWC and start installing the SIPs!

I have to admit, as it gets closer to a reality, I am nervous about the switch. I’ve been doing hydro for decades and don’t want to mess up a good thing, but I’m done with the RDWC.

I have questions about the soil being too moist from wicking. I still haven’t decided which one to buy. I have questions about using just organic soil and no ferts! I wonder how big the vegged plants should be when I place them in the SIP. Help! :)

It also worries me just how dead this thread is these days.
ill get off my ass and get you a couple of pictures of the sips growbox and earthbox so you can see the comparison,,, one of the nice things about buying these sips is the thinking is already done, they wick perfect and the soil is just right,,
I have always done bag soil and the Trench of dry nutes,, always a perfect run every time,, its so darn easy you will love yourself for doing the switch,,, i kid you not,,

Let me tell you I do not miss mixing nutes
OK, so in hydro, you have nutes designed for vegging and low N nutes for flowering. How is it that a souped-up soil can deliver the correct amounts of nutes throughout the life of the plant?

Kidding aside soil , well good soil contains all building blocks for plants , I have not dived in to no till soil myself, but those guys are the one who can technical answer that question for you , I grew hydro years ago on a garage, but now I buy high quality soil and use dry organic nutes and I stick the plant in and just ad water the whole ride, as I sit here this afternoon smoking the fruits of my labor or hahaha lack of work , what ever goes on down in that dirt is all this guy needs

Also you should use the trech method I showed a few posts back because after dumping the dirt out after the grow the trench is still there with nutes still in it and the plants send just a few roots right into the trench some were thick fat roots like it sent feeders I to the trench , and the water roots in my sip res look like water roots you would see in a dwc ,

Yea, I need to look into the trench. What dry nutes do you use? Where exactly does the trench go?

so i dug thru this thread and found my old pics,, with the earthbox you can see i had to space it up on blocks and put a pan under the over flow, this in turn caused many issues,, leaks, over flows, and more,,, with the grow box you can see the deeper res,, but its 2 piece ,, you can see the res, right thru the front where you fill it,, and you can see how much water is in the res at a moment,, where you cant with the earthbox, 4.JPG 2.png 3.jpg4.JPG 2.png 3.jpg

, here is the trench video
now this video is simply to show you how to do the trench,,, i am not suggesting you reuse last years soil ,, because the guy in the video is just a patio gardner and is growing his summer veggies probably,
I use organic tomato nutes, hahah been working like a charm, i used to use Happy Frog Fruit and Flower organic dry nute, more geared for flowering,
he puts the trench in at 4:40 mark

he shows how to position the trench based on what order your going to plant plants, ,, a long row across the middle if doing long rows,, i did the 3 short trenches, left center right, because i grow 2 cannabis plants

in this picture you can see how the length wise trench goes, and then cover the trench with 2 to 3 inches of soil,, when growing in a earthbox/growbox you pile the dirt up above the top fo the container, in a mound, the center of my mounds end up about 2 inches higher than the sides of the earthbox, because you never top water,, this way you get more soil in your sip, i can fit an enter bag of Fox Farms ocean forrest 1,5 cubic feet in 1 earth box by doing this method
