Athosanswered grow question 7 years ago There are many factors that might make it cheap or expensive: amount of light, media used (hydro, coco or soil), nutrients are the most important.
Let's start with light: I'm using screw led bubs (you can check my diaries). 6 bulbs to be precise. That's 60 watts for veg and 78 watts for flower (first time it was 60 watts for flower too) and it allowed me to harvest 50 grams, enough for personal consumption between harvests. With 78 watts (6*13 watts bulbs) I expect at least 60 grams, something like 2 jars of dry bud.
Media. Go with soil, it's simple and a good substrate will feed the plants for weeks, saving you expensive nutrients. Any heavy mix, complete mix, all mix will do. I use Biobizz Allmix, because it's easy to find here and cheap, there's also Plagron Allmix, Topcrop heavy mix or complete mix, canna professional or professional plus. I use 3 gallon/11 liter pots and it only needs additional nutrients 4 weeks into flowering. That is 3 to 5 feedings depending on the strain.
Nutrients. Go simple a flower nutrient and a growth nutrient, depending on your water quality you might need a calcium/magnesium additive, but only get it if you see a glaring deficiency. Don't buy anything like boosters, finishers or the more expensive stuff. I use Biobizz Biogrow and Biobizz Biobloom, that's it, nothing else from their line. There are others of course, this ones are easy and cheap to find here.
