Hydroponics Growing Methods
Any tips for converting from convntional growing to hydroponically grown crops?
I am a farmer in ireland who grows soft fruits and have a desire to convert from convntional agriculture to hydroponics to diversify my crops grown for example soy beans,grapes ,exotic flowers etc.I currently own 12 acres of land and am wondering which is th best means of doing this ie the best method of hydroponics to pursue and is economically viable with or without automation
Hello shane
There are as i'm sure you have found out that there are many hydroponic systems for growing that's on the market, but for growing on a commercial scale, if you would like to, then there's two main hydroponic systems, for water loving plants like lettuce, then most farmers would use "deep water culture"basically a shallow pool, as large as you like,filled with highly aerated water, and the plant are held just above the water, on Styrofoam sheets that float.but very expensive on a commercial scale.
For most other plants there's NFT, "Nutrient film technique" much larger plants and a wider variety can be easily grow, with just a small amount of specialized equipment, and the way it works is by using channels, "like the SQUARE down-pipes on some houses"and have a steady flow of water continually flowing past your plant roots,commercial systems would cost thousands upon thousands, although if your inclined you could easily build your own, and for not that much money, maybe start with a scaled down version, then expand the system when you feel more confident years ago i worked at a plant nursery which also grew tomatoes for the attached shop, and i converted one of the glasshouse to Nutrient film technique, and the local village community were very interested, specially then we did a small leaflet, telling of the benefits.
below is my hobby site, although i can only add pages when i have time, follow the link that's on this page, and add the RRS feed, so you no when I've updated

Checking and adjusting pH level is a common practice when using hydroponic nutrients . In fact, in case with hydroponics, it is not that difficult to do this job, as it can be with organic or dirt gardens. In general, there are several methods to check the pH level of the nutrient solution in the hydroponic system.
Special paper stripes, saturated with pH sensitive substance, change their color when submerged into the nutrient solution and thus show its pH level (to define the exact level of pH the color of the stripe is compared with a color chart). This method of checking pH level is widely spread for its cost-effectiveness; however, sometimes it may be challenging to define the exact pH level, since the color shades can differ slightly and be difficult to read.
Another popular method to check pH level of the nutrient solution is to use liquid pH test kits. They work similarly to paper stripes, with the only difference that these are in liquid form. A few drops of pH sensitive dye is added to a small amount of nutrient solution, and then its color is compared with the provided color chart. Liquid pH tests are easier to use than stripes, because they give more definite color, which is easier to read and define the exact pH level.
Digital pH meters are the most modern and technical way of checking pH level. There is a great variety of such devices on the market, ranging in size and price. The most popular pH digital meters for starter-gardeners are those made in the form of pens, which are very easy to use. Just dip the pen into the solution for a few seconds and read the pH value on the display.
Digital pH meters provide very accurate information on pH level of the solution. However, these devices are pretty fragile and should be handled with care. It is necessary to keep the glass bulb electrode clean and wet all the time. It is recommended to keep the electrode in special storage or buffer solution. The main thing is not to let electrode dry out. Since this electrode is the most sensitive element of pH meter, the whole device may go out of use when the electrode is damaged.
Besides, pH meters can be sensitive to temperature, which may influence the accuracy of the displayed pH values. To prevent mistakes modern pH meters are equipped with ATC or Automatic Temperature Compensation systems. If your pH meter does not have the ATC feature, try to check pH levels at the same time of day to minimize errors, related to temperature changes. Another recommendation about pH meters is to calibrate them regularly to ensure accuracy of the displayed pH levels.
Because pH meters may sometimes go out of use in the most inappropriate time, it is recommended to have some back-up option to check pH level, for example, a paper stripe or a liquid pH test kit.

New growth of Nesaea red coming in green?
I recently ordered a bunch of nesaea red for my 10 gallon tank. It came in a beautiful red color but now after about a month, all new growth is coming in green with only a hint of red to it. Is this a low light problem or a nutrients problem?
I currently use a 12 watt 900 lumen CFL bulb on the tank(it sits about 5 inches above the water level) and add a liquid fertilizer by Aqueon (about 15ml-20ml a week).
What can I do to get the new growth come in red?
It's both a light and a nutrient problem. A 12 watt CFL isn't strong, and the Aqueon product isn't much good either. For Nesaea red to achieve it's best coloration, you should be looking at no lower than 30 watts (depending on light type), a good all-around fertilization routine strong in iron, and the addition of CO2.

How can I tell which digital cameras have the self timer function?
I want to buy a digital camera to take a pic of myself and the jargon in the "features" lists on all the websites I have checked including Argos has not given me any clues.
http://www.shortcourses.com/images/b4ch2/self-timer%20icon.jpg
This is the icon that will tell you if it does. It should be on the option wheel of your camera. Great luck!
