Hydroponic FAQ


I did not have any kind of Hydroponic FAQ when I was building my first hydroponic system. And I did not have a clue what I was doing. I realized quickly I was 'over my head' so I decided to buy a prebuilt system which featured a semi-submersible pump.

This meant that the bottom half of the pump had to be submerged while the top half had to be dry. This also meant that sooner or later the pump would fall over into the nutrient solution destroying the pump and maybe electrocuting me in the process.

Well...this actually happened.

The pump accidentally fell into the nutrient liquid while plugged in and destroyed itself in an impressive display of sparks. Fortunately I was not hurt but I was out a pump and a fuse (and I learned that semi-submersible pumps were worthless). But having more stubbornness than smarts I persevered and finally got it right...


(By the way, this is not a picture of my greenhouse - I should be so lucky)

Now I'm in the position where I can actually help others succeed with their hydroponic system rather painlessly. And since I'm mailed so many questions about hydroponics in general I decided to create a Hydroponic FAQ page so people can find answers quickly and easily.

Questions or comments can be mailed to me via the Hydroponic FAQ form below and I'll post the question as well as the answer. The best part of this is it's interactive nature where others can also respond to questions and comments.

Below the following list of hydroponics questions and answers you'll find the simple form where you can post your questions and/or answers.

So, let's begin!

My Most Frequently Asked Questions

Question: Can your systems be imported and utilised in the UK? We're on a different power supply to yourselves?

Answer: Yes, my systems can be used anywhere in the world. In fact the UK has more hydroponics equipment than the US and since the basics of most of my systems is a pump that is all you need matched to your power supply. Even if you obtain a pump made for US voltage I'm sure there are adapters which could probably be found in places catering to business traveling. You could even ask an online hydroponics store for pumps that work with UK power... So get the proper pump and you should be all set.

Question: Your "plans" link to the PVC greenhouse seems to be a dead link. Any other path to the plans??

Answer I noticed that and could not find a new link which is really too bad. For now I took it out but I have detailed instructions from that site so if I manage to contact the owners somehow and get permission I will put them in my site. Thanks for the info...

Question: I like the ebb and flow system and am thinking of building one. I have a question. Is it a good idea to buy seedlings from the garden centre and then wash all the dirt off the roots and plant them in an hydro system?

Answer: Yes it is. Buying them and washing the dirt off is faster and easier than germinating the seedling yourself.
