Start with the right tools when growing hydroponic cannabis. Get a good quality PH meter, in hydroponics it is one of your most useful things you will need. Keep your PH calibrated every week will save you a ton of headaches. Get a good EC meter to measure the total salt content in your nutrient solution. Don’t use the recommendation on the bottle. It’s always way to much, and over kill. Normally you can half it with no issues.
Make sure you have something to stop flooding, if a line gets blocked or a drain gets clogged it’s going to flood you room/tent. This will ruin your pump and your floor.
Start out with the basics first. You will find some companies will be selling bottles of this and that. Keep things as simple as you can when starting out, this will not only be helpful but will save you a ton of money.
Do your research on types of hydroponic systems, there are many of them each with their pros and cons. Find a system that works for you and your space. If you’re growing in a hot space you’re going to need to cool the nutrient solution, a cool space then you may need to warm it. These are things you will need to think about when you would like to grow hydroponic cannabis.
