Flush bottom feed
MiistrHstarted grow question 1y ago
I’m using an autopot (bottom feeding) system. They say not to flush because of the salt buildup. But is the “shock” of those salts bad or is it the salts staying in the bottom what is bad?
In that case if you thoroughly flush (say 50+L in 20L pots) would that solve the problem?

Flushing through the tops of the pots will send high concentrations of potentially harmful salts straight back into the root zone. According to autopot if you use the system as intended then a salt layer accumulates towards the top. If your doing it by hand I figure you'd need to dump a few gallons of water in to get out the excess nutrient.
Remember good old tap water is still filled with at least 400ppm of mineral salts too.
Salt buildup will cause too high ec, pH will drift, causing the appearance of nute deficieny.
50 l sounds good.

Yes of you run 2.5 that amount of the pot in water thru it that should wash out any kinda build up your worried about.

Fertilizer for flowering phaseHi! What should a good fertilizer contain, suitable for the flowering phase? And what could I use if I want to buy it in a hardware store? Or can I just keep using my normal fertilizer, that I also used during the growing phase? Thanks for your help :)Week 8

Which automatic watering system while travelling for 1-2 weeks (closet tent, 2 plants)?1.) Which specific systems are proven effective and safe (commercial or DIY)?
2.) Will pH change over days if adding pH +/- to a water tank?
3.) Would you leave the plants for 1-2 weeks with the system running (LED, fans, electricity, potential danger of short circuit/fire?)Setup. Other
