Easy to use, not a lot needed each use. No mad scientist moments with mixing. The plants have done very well handling stressors, largely due to good nutrition.

This kit is awesome, plants loved it , ran side by side vs another brand , and this 1 outshines other 1. Only drawback is price, expensive for what you get.

Nearly foolproof, but you will need some extras imo.

The golden tree smells like rotten eggs, badly, so use that outside. The rest don't smell like flowers either do I'd just stick to mixing it outdoors but, of course, store it indoors in a cool, dry place. This kit doesn't come with the Tree Trunk or the Sweet and Sticky additives which I recommend you add to this purchase as well as getting yourself a syringe that measures in ml up to at least 10ml to make it easier to follow the directions as they are in ml and it's a lot less messy and smelly. Just be sure to **** up and shoot out a little water between each nutrient and never mix raw nutrients. They do leave out that you should be watering with normal water at least once between feedings, but if your buying this kind of kit chances are you already know that. Start lower than they recommend, I'd start with half as much, and work up from there after you see how your plant reacts. Make sure you have that pH and PPM tester and measure after it's has been mixed throughout and has settled for about 5 mins. Also, record EVERYTHING you do in a journal. Measurements, water amount, water schedule, problems, etc etc... We all know our memories are not to be trusted. The pH of your liquid should be between 5.5 and 6.5, I shoot for 6 myself, and the PPM will vary according to your particular plant but generally around 800 to begin with and peaking at around 1500. This can only be known through experience, if your lacking that just keep it around 800-1000 and you'll be fine I'm sure. I'm an idiot and I make it work... TL:DR You will need the basics of course (tent, light, dirt, pot, and quality water), but adding these things to this kit will help a ton, all sold right here on Amazon, but remember price reflects quality and accuracy usually. Read reviews. - pH tester (liquid tester) - PPM tester (liquid as well) - syringe that measures in ml to at least 10ml but size isn't as important as increments, make sure you can draw 3.5ml exactly, for example. (syringes work best with less mess, and some of these nutrients smell bad) - Hombolts Secret additive "Tree Trunk - Hombolts Secret additive "Sweet and Sticky" (both round out a complete start to finish system that works great and by following the same brand you know it is compatible and compliments each other well)
