Auto watering cannabis

Now you need a growing table so that the water can drain out under the flowerpots and flow into a tank which you can then empty – never reuse water from these kinds of systems, and always ensure that your timing is right so that you don’t waste precious water and nutrients, as you’ll basically be throwing money down the drain.

Air pump:
Air pumps are used to give the water in your tanks more oxygen as well as keeping the nutrients in constant movement, which is something that your plants will greatly enjoy. You’ll need to place an air stone so the oxygen particles are smaller and easier to mix up with the water.
You need to program the watering so that when it waters, it only gives your plants the amount of water they need for one day – you can’t water a 10cm plant with two whole liters as you’d end up soaking the soil, the roots will rot and you’ll probably end up with a dead or hardly productive plant.

If you’re growing in soil it can be hard to get the timing right, and if you mess it up twice in a row your plants will suffer quite a lot, which is why we recommend using a different kind of substrate with better water drainage if you want to use this automatic system.
You need to place a submergible pump into your tank which is capable of maintaining pressure in the pipes, so that the same amount of water comes out of each micro-pipe so that, logically, the plants all receive the same amount of water. You’ll need to install a pipe system that then connects to micro-pipes used for drip irrigation – make holes in the main pipe system for each of your micro-pipes which will then be used to water your plants. You can get pipes that can deal with 16 of these micro-pipes, or drippers such as the Octopussy, which has 6 micro-tubes etc.
The last thing you need to do is get an air pump with an air stone, which will ensure that the nutrient mixture and the water is in constant movement and oxygenized – your fertilizers won’t end up accumulating on the bottom and will always be available for your plants once the pump turns on.
Flood table:
These are trays that have grooves in them so that you can direct any leftover water to a specific point, where you can then channel it through a pipe to wherever you’d like or simply leave a tank underneath the hole on the tray itself so that the water can fall down into it. These trays are easy to clean once the grow is done and they’re very efficient when it comes to getting rid of water so that there’s never any leftover water sitting at the bottom of your pots and soaking into the soil. They’re also useful in the fact that leftover water from one plant has the opportunity to be absorbed by another plant, which can help avoid all sorts of salt excess in the substrate and whatnot. There are various sizes available to fit your exact needs.
If you decide to use this method, keep in mind that your plants won’t grow the same than if you were to hand water them and mind them one by one – if you have lots and lots of plants, then doing this is probably not in your best interest. You can also do this if you don’t have time to water your plants and you only have a few in your grow tent, but keep in mind that the yield will be a bit lower.

Watering pipe:
This tube is used placed in a straight line between two rows of flowerpots or slabs, and the micro-pipes are used alongside the sides of the main pipe – the main pipe is in the middle and then the plants are to the right and left of the pipe, kind of like a corridor. You’ll need one line of pipe per two rows of plants and then you need to place the micro-pipes – there are various models, some of them just need one hole in the main pipe and have 6 different drip pipe endings, some have 12, and some require one hole in the main pipe per drip pipe. You’ll need to pay close attention to the pipes in case they accidentally end up blocked – if you use Ata Clean in your grow about once a week then you can forget about worrying about blockages in the micro-pipes.
