    I added the Autopot root sock to the bottom of the pot to prevent any coco or perlite flowing out into the fill valve and jamming it. The wicks were filled with 50/50 coco perlite mix. I covered the bench and wicks with two layers of weed cloth and then added the grow medium. I'm going to...

    So, I modified the large 6.6 gallon Autopots. I created a bench for the growing medium with two wicks. This provides for an air gap between the water reservoir and grow medium. I used a piece of 1/4" thick food grade HDPE for the bench. The wicks are 2" ABS pipe and there are two additional...

    Did you have two plants or one in the container?

    That's nice that you have 7 feet of space, seems like you can make it all work with the Inntainers. You could also convert to LED to get more head height. ;-) Yeah, I only have about 40 inches from the top of my pots to the bottom of my light when it is raised up as far as it will go... hence...

    What is the height in your cab? Those Inntainers are around 16" tall. I may even try mine out in my closet, but I may run into height issues to because my closet is only 5.5 feet tall.

    Wow, quick veg! Now I'm a bit embarrassed to admit that I've had my plants in veg for 9 weeks, although it was my intention to only veg for about 7-8 weeks, but I decided to wait to go to flower until I get my order of the larger Autopots and get them transplanted. Damn order has taken forever...

    How long did you veg for? I'm new to indoor growing so I'm trying to get a sense of container size to veg time. I vegged my current plants in my Autopots too long in an attempt to maximize my SCROG net and they are not happy, so I'm going to transplant into the 6 gallon Autopots before I switch...

    Nice and healthy looking.

    Yes, this is the small version designed by Ray Newstead. His nickname is Raybo on the tomato forums. I made two of these smaller versions and these are the ones I used for my outdoor cannabis and hops. They're also a bit easier to move around. The larger versions are a bear to move.

    Yeah, in general the regular tomatoes tend to be a bit watery and bland. The cherry and roma tomatoes rock... their flavor is great and I get tons of them. I think it might be because they can't get too big with water and they ripen quickly. The SIPS work great for cucumbers and greens...

    With tomatoes and other plants like cucumbers if too many roots get into the reservoir then my veggies seem to have a somewhat bland flavor over the ones with roots that stay in the soil. I'm not sure if this would make a difference with cannabis... maybe affect flavor? Also, I like the idea of...

    The large Earthtainers use 31 gallon totes, but the soil capacity is 24 gallons. The half water barrel SIPS are 27 gallons, but probably about 21 gallons of soil. The wick on the Earthtainer is a 5" net pot filled with peat/ perlite mix. Here's the design I used by Ray Newstead. His manual...

    Let us know how you like it in the SIPS. I may start by trying their stuff in my outdoor SIPS this summer.

    You love the Buildasoil? Do you use it instead of dolomite?

    SIP thread -- (Sub-Irrigated Planter)

    I've never used powdered dolomite lime, only pelletized dolomite. I've looked for the powdered stuff, but have had a hard time finding it in the past. I do believe the powdered version will work faster. I think oyster shell flower might also work faster, that is why I'm interested in the...

    Watch out with adding biologicals to your wicks. That could potentially cause some bad stuff to grow in the reservoir. Also, introducing air down low is usually a good idea. As the reservoir water drops it sucks in air and almost acts like a lung so long as you provide a way for the air to...

    Usually about 1-2 tbsp of dolomite lime for every gallon of grow medium. But, you can be generous with dolomite lime and still be okay because it does break down slowly.

    I agree, the dolomite takes awhile to break down, but it is nice to use if you're reusing the soil. My outdoor containers go about three summers before I change out the medium. I'm really interested in the Buildasoil mineral mix for peat. It looks like it has ingredients that with supply...

    So far I have always used EB Stone in my SIPS. I use their Tomato & Vegetable Food 4-5-3 in the fertilizer trenches. I also mix in some of their Sure Start 4-6-2 throughout the grow medium around the root ball in addition to dolomite lime (growing in peat). But, what I have found with the...

    Hmm, well... the base is peat/ coco with some perlite... so that part is a good start to having a lightweight mix that can achieve proper capillary action to wick water up. However, the thing that would concern me about this mix is that they imply it's pretty hot stuff with the way they want you...
