I used to have small 4 Liter bucket with just air stone, nutes sediment were concentrate at the bottom and make the ph spike daily and needed a weekly res change. I changed for large 20L bins you get at walmart added a good water pump and I don't bother as much if any at all. No root smell, no...

Brand and room size ? Thats what led are for, on a board of 300 led rated @ 10w a led chip you'll have a rated 3000w equivalent led light pulling abt 400w from the wall. Same for inhouse led, they are rated eg 65W for your socket but will pull only let say 10w thats the reason they are as...

I also do dwc, if you have good water pump for water flow and good air stone you're set. Ph raise by .1 is nothing but you need more than just ph, you need to know at least 1) ph, 2) ppm/ec 3) water level. Look/Print this chart...

Temp rez I dont care to certain point so dont bother with a chiller for now, this is expensive. But 74 (23 c ) is very low in my opinion. I go that low for bloom only at night/ lights off. But in veg I'd go 26c ( 79f ) minimum lights on and off. They seem to be cold.

Interesting, this run I was trying to put very little nutrient to avoid burning like I did my last run ( this is my second run ever growing ) I use 1/4 of AN supplement feeding chart ( bloom, grow, micro, b52, big-bug ), that I do once a week then only ph water if needed. Maybe running 1/2 the...

Hahaha sorry, should have known better :) yah this one in particular is in soil. Would only low ph cause this ? so bringing her back tin the 6.5 range will fix it ?

Just a normal tent.
