Hydroponic Systems.

Posted: 19/02/2016 at 09:58

The system I have used in my greenhouse for the last 15 years to grow my little gem lettuce is a shallow plastic box (the type that is sold for under bed storage), and a fish tank aeration pump and stone. Very low cost and cheap to run. Just fill the tank with water add nutrient (1.3 EC for lettuce) adjust pH to 6.5. Drill suitable holes in the lid for the roots to pass through into the nutrient mixture. I germinate seed indoors on damp toilet paper in a small plastic box, transfer to a Perlight/Vermiculite mixture  in a  bottom watering tray to grow seedling on until they are big enough to transplant to the bubbler tank. Keep germinating seeds as you harvest for a continuous supply of lettuce.


Is it me?

I enjoy GW no matter what it covers week to week, and have been watching TV gardening since the black and white TV Percy Thrower days, it's never boring, Granted somtimes most af a program will be centered on a particular garden event or subject that I am not particularly interested in, but I am sure that there will be many that would feel that it's a highlight episode for them, When I do find that an item is of particular interest to me I often feel that it is given only scant coverage and should have been gone into in greater depth. Over time producers, presenters, etc come and go so the flavour of the program will change to reflect this. Let us remenber that the BBC has the impossible task of being all things to all men.


While we all keep wishing for more of hour GW I think they have it about right.


Except of course if the program is dropped in favour those who want to watch 22 grown men chase a bag of wind round a field in all weathers for  90 minutes!

Greenhouse Heating

Posted: 01/04/2013 at 17:12

My greenhouse base is of 3"x2" paving slabs, they warm up during the day through natural radiation. (Keep your glass clean for maximum effect) I have not recorded specific tempereturs but it is noticably warmer inside when entering in the morning.

Starting my early seedlings I have an plastic box with water in it and insulation round the outside. using a 100 watt thermostaically controlled fish tank heater keeping the water warm. The top has a plasic lid with small holes drilled it. I place my seedling trays on this lid and cover the whole thing with a home made mini greenhouse, this keeps the warmth and humidity up at minimum cost. I have for the past four weeks had this in operation for the past four weeks during the feezing March weather. The tempereture inside the mini greenhouse is kept at 60F.My Tomatoes and Lettuce love it. Checkout the picture.


change soil?

I have a small raised bed that used to be troubled with cats, until I found the answer.

Green plastic coated chicken wire cut to the width of the bed, and laid across for full length.

Easily lifted one at a time as required to sow seads, then replaced until the plants grow through the mesh. As the plants get established and before they get too big, I lift that section of mesh and hang it in my shed till required again. As I harvest crops I fork over that section of soil and sow the next crop, replace the mesh on top again.

End of season I clear the bed removing weeds etc, and leave covered with mesh over winter. This gets the cats out of the habit of using this area as a toilet.

I have 2 8x6 Aluminium, one from local add and one from a Wanted on freecycle.

As long as you are prepared to dismantle and collect, ( albeit with one or two broken panes) you should not have any trouble.

Good luck.

Is this weeding?

Weeding and tidying up?

My own definition of a weed is any plant I don't want in my garden.

Tidying up can mean so many things to so many people.

One man's rubbish is another man's antique.

I have not had occasion to have to tackle ivy (yet), but have successfully managed to kill off established trees in the past willow, leilandii, and, ash, all close to foundations and drains,

1 cut off and remove top growth leaving a stump.

2 drill a 1/2"-12mm hole vertically into the stump.

3 fill the hole with neat SBK and cover the stump with kitchen foil lid tied on, to keep out the rain.

4 check periodically as the stump absorbes the SBK, top up and replace the lid.

As I see the bark on the stump start to break away I stop topping up, and have not seen any regrowth at all. Plants growing close by don't seem to get affected.

Affect on adjacent tree roots etc, maybe advise from the manufacture of SBK on using this method would be wise, as it is pretty strong stuff.

Just picked up on your post from last July.

As a non comercial amatuer gardener I have been growing with Hydroponics in my greehouse since 2004. A few failures but mostly successful. I have my own working notes now compiled as a PDF document

If you care to send me a message back with your email address I can send you a copy of my document "Growing by the Hydroponic method". This should get you started.

Regards Hydrogrower TJ.

Hi BrummieBen,

Loads and loads of questions when starting out I know. Just to give you an idea, I grow ten Gardeners Delight Tomatoes in a 8x6 greenhouse. In 2008 I recorded  the exact nutrients used and also the harvest from that input.

Nutrient used 8.9 ltr, Harvest 63kg, Work it out.

I found that visitors to my garden were full of questions about my Hydroponic setup, and I was having to explain it all over and over time and time again. This decided me to put together a 12 page PDF document with pictures of my own experiences and this answers a lot of questions for beginners, that I could just email to anyone interested. I cannot see a way to upload this document to the forum but am happy email it to anyone interested.

Regards TJ

Hi Paul.

Glad to hear from you. I was beginning to think that I was the only in the UK using this method.

What sort of setup do you have, what method do you intend to use, and to grow what?

I myself like to grow Tomatoes, Lettuce, and Sweet Peppers mainly. Over the years I have had success with Cabbage, Calabrese, Peas, Onions.Runner Beans, etc.

I use 2 systems mainly NFT and Bubbler tanks.

Be only too glad to help with any advice I can offer, no point in you re inventing the wheel by making all the mistakes I did.

Regards TJ.
