I dont use seals anymore. I was using aquarium seal for a long time, and still do in certain situations. A natural seal is always the way to go in my estimation.

I use tubes inside of other tubes to seal up holes. Notice I have a garden hose here. Inside it I have a 1/2" 1/2", and a 1/2" 5/8" interior/exterior diameter hoses. These form a seal when pulled through that locks it into place at bottom of bucket. This way of sealing fittings is important for many reasons, namely the weight of water we are talking about and having the bucket non-static(moveable). An unnatural seal such as glue or silicon can break if you disturb it, ultimately setting you back.

Pictures-

1. Cleaning the seals is important for tight fights. We will use garden hose in this DIY for cost and versatility. You can use different types of fittings and I will explain these later.
2. I like using clear flexible and black stiff tubing. Here you can see the 1/2 1/2 black inside the 1/2 5/8 clear. You force this into any garden hose and it will be such a tight seal, that you will get a workout trying to get it in or out, but you will know its safe. You have to insert the black inside the clear, then then clear end into the garden hose, then pull clear through other end of hose till black reaches the garden hose, forming a seal, then you pull it through- this requires physical strength.

3. Once youve pulled it through, thats how it should look from the inside. Black opaque hose 1/2 1/2 in center, clear 1/2 5/8 around it, garden hose (standard type) outside of that. The hose has been pulled through with the black 1/2 1/2 forming the lock in the 1" hole. The garden hoses with the mat finish, rather than a glossy-slippery finish, work better because they don't slip around as much.

4. Here is another example of that self-sealing fitting that I used in another type of bucket- this is an unrelated design so do not let it confuse you. This picture illustrates how this connection has been a very easy, inexpensive, and versatile way for me to connect units within a system.

AquaponicHerb Reviewed by AquaponicHerb on . Suckit Bucket DIY This is a DIY for those interested in experimenting with new grow methods. I will explain as best I can, but ultimately I will need questions and prompts, as these concepts can be unorthodox. I don't claim that this system is better than any other, however it does use concepts that are not new but have not been combined so far as I can see. I have documented the growth, and you can judge for yourself whether this is worth it or not to build. There are lots of systems for different Rating: 5
