Hydro. Buddy v. 1. The First Free Open Source Hydroponic Nutrient Calculator Program Available Online Hydro. Buddy is a completely free and open source program for the calculation of nutrient solutions for hydroponics and general agriculture built by me Daniel Fernandez based on my experience in hydroponics as a professional chemist. Introduction Understanding TCP keepalive is not necessary in most cases, but its a subject that can be very useful under particular circumstances. NewLISP Users Manual and Reference.

Foreman 1. 3 Manual Foreman Architecture. A Foreman installation will always contain a central foreman instance that is responsible for providing the Web based GUI. This piece of software was coded from the ground up using the Lazarus open source programming suite and implemented using appropriate database solutions as well as a  powerful linear equation solving algorithms from Alg. Lib. Hydro. Buddy is available for Linux and Windows. Hydro. Buddy is released under the GPL license. For Linux or Windows installers are included. You can also use on Mac. Songsterr App For Pc. OSX if you compile from source. These are some of Hydro. Buddys features Calculates the weights of specific substances needed to arrive at specified concentrations of different elements formulation to salt weights calculationEasily fine tune your salt weights after calculations. Calculations in ppm, mmolL, molL and meqL. Calculate liquid additions in m. L and add any custom substances as liquids. Edit the percentage elemental composition of each substance or add new ones to fit your needs. Powerful open source linear equation solver provided by Alg. Lib. Always tries to find the best mathematical fit to a formulation by a given group of substances. Allows to get the concentration values for the addition of a certain specified amount of substances salt weights to formulation calculationEasy to use interface for the addition, edition and assignation of substances to calculations. Data logging module to help you track the EC and p. H of your crop. EC prediction module based on an empirical mathematical modification of a calculation based on limiting molar conductivities. Use the resulting weights of a formulation calculation to perform a calculation of the opposite nature and vice versa easily allows you to see the effect of manual modificationsCalculations for both direct additions and AB concentrated solutions. Use any custom substance as a part of an AB concentrated solution calculationCopy Commercial Nutrient module which allows you to copy the ppm results of a commercial nutrient formulation. Water quality module allows you to include water quality analysis within the calculations. Adequate implementations of instrumental and gross errors with custom instrument precision input. Proper database implementation allows you to easily save your custom formulations. Set default water quality and data log data sets that load automatically on program startup. Save and load formulations using any concentration unit. Choose between grams or ounces. Choose between liters, gallons and cubic meters for volume inputs.
