By far the biggest yielding grow came from using spider farmer wicking pots!! Very Easy to set up. Crazy root zone development, huge , healthy plants. Here are two tips id like to share. 1)I found when adding water adjust ph lower than usual because it creeps back up after a few days. 2) clean out the basins every now and again to ensure flow and prevent root rot etc. I definitely recommend this system.

OK, one of my pains in the butt about growing is watering of course. The system is awesome because it doesn’t depend on power. If it goes out, you’d be screwed. I finished one harvest and starting another in Flower. I give them the nutrition through the top every three days Otherwise just keep the container full once a week have to fill it. Love love love this product I can go away for a weekend and not have to worry.

There is nothing more enjoyable than watching your plants react in joy with all leaves pointing upwards after reaching the wet shoestring from a water basin. It's really important that you read the instructions including the yellow sticker on the plastic black device that controls the water. You'll need to remove a Styrofoam piece. Failure to do so will prevent the device from working correctly and lead to failure. Also, failure to put the gaskets in correctly from the outside into the hole in the basin will lead to failure and flooding. This is an awesome system to keep the basins full of water. I connected 7 basins to one system and it really is a time saver filling a single 14 gallon container versus each individual basin. The main 14 gallon container is well manage and I'd recommend boosting its height by putting it on a smaaaall platform so the hose goes downward into the hole in the tent. I do wish the spout hole would be lower on the 14 gallon container. That is my only complaaint. I understand they put the hole higher for the gravity system to work but i dont like thewater sitting in the basin below yhe hole. This system works well when set up correctly.

I’m loving this system really a set and forget it easy to use and set up only thing I don’t like is not having a shut off to each base and you have to keep a eye on you reservoir for ph drift and so I’m not adjusting every day I ph lower when refilling but you can’t beat it for the price and it’s take 2 to 3 days to drift using a air stone

Quit playing the watering game. Highly recommend. Simply moisten the soil to get the system started, very dry dirt wont moisten up. Once everything is moist, it will stay that way, providing the perfect moisture level 24/7. Just keep the reservoir full of water. I found the bags that came with this setup is slightly thin, allowing the dirt to become super wet. If this happens, and dirt becomes too wet for your particular plant species, just use 1 wicking rope instead of 2, or upgrade to a thicker grow bag. I went with thicker, 7 gallon grow bags from a different company and the whole setup works amazing.

Have no issues with leaking . Plants grow much faster . Just watch for the roots growing into your tubing pluging the flow.

Not bad it seems to work pretty good I would’ve preferred a reservoir that was a sturdy plastic. If it ripped that’s a lot of water on your floor. It’s some kind of material that’s been sewed together. Perfect for shipping horrible for longevity. You can put up the 7 gallon fabric pots on these so that’s nice Inside the reservoir where the water flows to the pots. They have the fitting up a couple inches higher than the bottom of the reservoir. So you will definitely need to mix your water up because there is a huge spot that will not drain. If you’re adding nutrients you’re going to have to count for what is in the bottom of that also unless you lift the entire reservoir up and let all of the water run into your pots if there is room. That is a horrible design. Installation was straightforward and easy The plastic pots themselves seem to be very durable. They should last numerous years as long as you keep replacing the cotton. I paid $100 almost maybe a little more. I think it was marginally worth it. I don’t think I would ever buy again. I would probably go with an auto pot system.
