I have to buy a chiller but i cant find any here, i have to bring one in my next journey abroad...im in a third world country man, you cant even imagine how hard it is to get the things you mention....A chiller will take care of any chance for root rot and an ph perfect nutes makes dwc super easy. I'm growing biggest plant of my life and I don't even check ph at all or change res water. Literally all you do is add water to res every few days and pray your space is big enough for the monsters coming lol.
If you don't want to spend 300 on a chiller I recommend coco/perlite hempy. Also extremely easy and doesn't need a lot of babysitting. Just make sure you pre charge your coco with calmag.
Which percentage of mix do you recommend for coco/perlite? And can i load it with an nutes? Which ones do you recommend?and at what percentage?
Thank you all for your help, i really appreciate your effort
