First time hydro, going to try Ebb/Flow - is this a reasonable plan?

That is part of why I just keep running one strain over and over from clones off the previous batch.
It is amazing how humidity and temperature indoors, can affect the expression of the plant.

If you go unsealed without CO2, the best thing your room can have is an open window or door to outside for fresh CO2.
100% agree, fresh air is very important and why I run with a window open (unless it gets too hot and have to close it to run AC). I also have ExhaleCO2 bag hanging over the table which I'm sure adds a little bit of fresh CO2 to the room as well.

I also used to run the same strain from clones of the old clones over and over, and I did for years. Best ever yield I got was when I had the best ventilation from an open window on the third floor.

I didn't put the plug in deeply enough (it was catching on the timer), so the fuckers went without water for nearly a week... The one on the right and rear was the only one to droop (the inlet moved so it sprayed over it the last time I watered). Bounced right back though but stretched loads in a day after the watering. Actually forgot to turn the li8ghts up, they look ready to take the whole 300W. I'm nipping out the tips so they should be getting quite bushy.

Getting big, the roots feel about as thick as the batting now... had a peek this morning, to make sure the feed line is still pointed in the right direction... (something I need to work on a bit, I don't like the fact that it can move. I need a bunch of cuttings, So I'm letting them stretch a bit with lowish light.

Pretty sure one of the smaller plants is a male with its leggy structure.. Will take some pics tomorrow. I bought some copper-based stuff to clean them up a bit, they have a few funny spots after I let them run dry. I'd rather not take chances...

Also still need to figure out how I am going to sterilize the roots from time to time... I guess I can use peroxide or pool shock. It is not an issue yet. But it will become warmer soon.

Mine would have been dead by now if it wasn't for the batting.

It is a neglected grow, as I need to pass through 2 doors and a locked gate to get to them...

Gave them their first copper spray last night

um why (copper spray?) I do zero spray only but I smoke it, so.

Me too, but they are showing a few strange spots... Most of the plants will be cut off this week to make clones, so very little of the shit should be around by harvest time a few months down the line.

It all started with a few dirty clones a friend dropped off here... I first had to eradicate a mite swarm, and now this. Might be part of why my scrog is doing so badly too. But that tray is less than 2 weeks from chop time.

This thread has kinda gone all over but based off what i see in the beginning, the main point of all this plumbing is derived out of fear/concern over pump heat, right? In flood/drain if you're say 100% hydroton or grow stone, you're pump will be on for about 5 feeds /day. Add some grow cubes or other higher absorption medium to the mix and cut that in half. You may have ambient air heat issues, but with flood and drain heat issues from the pump should not exist since its hardly on. I'm into the plumbing though, I love the auto siphon trick, good stuff!

Every day I am thankful I switched from RDWC to Flood/drain. Anyways here are my roots at week 3.5 in flower.20180810_165315.jpg

Just gotta watch the roots don't fill the holes in my auto-syphon, I check that almost daily.

I know there's a bunch of factors going into making a switch like that - I had a few runs in standalone dwc buckets, totes, and then to rdwc but I'm curious, what was the crux of your experience with dwc? Sorry if I missed that somewhere else

I just didn't like having to worry about the water temp. My ebb and flow reservoir gets up to 85 degrees sometimes and is regularly at 80, and I have no root rot etc. Plus it was a super pain to change the water.

Nice man. Seems like we got fed up with DWC exactly the same reasons. I have a flood tray now myself and cannot wait to run my first flower with it
