yo mates… i come from croatia, im researching all i can for my first grow, my goal is to make open source automated grow box for dwc with custom everything, i like perfection, and i look at plants like a machines that need fine tuning, im electrician, but with some novice skills in programming in web languages, c++ and with some good experience building industrial machines and control systems… personally, i have researched growing for about 6-7 years now (lights, nutes, grow systems) just cause im a stoner, i promised myself ill make it ever since my dear friend died of cancer and with all my research trough panic and first time trying we couldnt make enough to have decent supply of medicine (1g of oil per day), so i came with this idea: you go to web page, input what you want (soil, hydro, 1 box or perpetual via more), you get out all the code and part lists and pdf for assembly (since fine tuning environment needs a lot of knowledge, and existing devices cost in thousands of euros, it needs to be on open source hardware), hope ill have alpha edition in a year or so, since im all alone and work really hard and dont have much energy left for it… allready have some basic made, design wise and some basic control, but i want to get to industrial grade machine level before i put out anything (pid control of nutes, vpd takes care of temp and humidity, filtration of air via hydroxyl air purifiers and power supply via solar and/or power generators since its illegal here to grow and its gotta be stealthy for about 8-10 grow boxes)… so basically, i have no advice to offer, but i appreciate all the effort you guys put into your grows and share so i can use it… my biggest need now is to find a way to make my own nutes by buying individual ingredients, and fuck, there is a lot i need to research for that, i need to do this cause of lower price plus there is almost none of the good powder nutes i can import in my country, or if i can, shipping is more than product costs… big love and respect!
