The question of root rot and hydroponics, when the plant is young you won’t have much of a problem, it’s when it becomes large you may. Peroxide will work, but it’s not an inoculant, so it is not as effective. I use Botanicare Hydroguard which is an inoculant, not too expensive, and eliminates the possibility before it ever has a chance to start. It’s just one of those things I prefer not to gamble with.
@BoboLacetti, Super, cheers Bro for the reply.
I want to get myself a Mars Hydro DWC too, I'm doing some calculations with nutrients right now.
I'm thinking of starting with 5 liters, changing it every week for a new compote. And in the middle of the week just top up with a couple liters of pure osmosis water.
Are you topping up the water during the week?
