Clusters of white stuff in my watertank (hydroponics)
Newbie101started grow question 2 years ago
When I stur in ly water tank, I notice some white flake like things comming up. It lays at the bottom but when I mix the water, it spreads out and some settles on the surface afterwards. I tried to take a photo, but it’s hard to see on them. Has anybody had this before?

Could be precipitating certain things in there.. if you add things in the wrong order it happens.. I noticed when I used silica it’s finicky about temp and ph of water you add it to. Always put silica first, then cal mag, then micro, then everything else.. if it’s a system like GHs flora trio

I was coming onto the exact same thing that hempkid is saying. I would start there and get your water tested

Probably (not 100% sure) could be hard water. I have similar from excessive amounts of calcium in water. My PPM straight out of tap is 250.

Musical plantsDo you pump music for your plants🎶🌱 I know there is some science behind this, but have you actually noticed any difference!? I've read they prefer classical or heavy metal 🤘

Hydroponics and tent height issuesI'm looking into hydroponics, and have been looking at the GHE waterfarm. But worried that with a pot being 37cm and my tent being 120cm, I'll run out of space. At least having to turn down my light to prevent bleaching or heat damage. Any advice on this?Week 1

Isolating grow tent humidityI recently got a humidifier as my tents RH was 25% with no correction. When I first put it in it didnt do much because of my exhaust fan. Untill the room it vented into was the RH I wanted my tent to be it didnt stabalize. I dont want the whole room at 60% RH though. Advice?Setup. Other

Low humidity issueTents 20'' × 30''. Using a vivosun 6'' inline fan to exhaust with passive intake to create negative pressure. I have a good humidifier but even on full the rh doesnt go above 40%. Not unless the room the tent vents into becomes super humid as well.

Encouraging heightI just raised my 900w led to 39". Feeding every day about .3 liter. It looks like she will have 8 main colas after the 4-way top but I'm concerned about height. Should I wait for 4 nodes on the new colas and then switch to flower maybe? Thanks for the great advice as always!

My tent is 32"x32"x63". I've only ever done one plant at a time. This time I am attempting to share the tent with a hydroponic grow in a 5-gallon bucket. I normally grow soil in a 5-gallon smart pot. Should I use a 3-gallon instead? Last grow the 1 hydro filled the tent.Week 2
