#marshydro13th #marshydro #FC-E6500 Another awesome giveaway by marshydro. Everyone check it out give it a shot! Thanks @MarsHydrofactory we appreciate your commitment to the grown industry.

Whats up all, looking for some seasoned dwc growers options. Quick background I've been growing 2ish years now, only dwc and only GH trio nutes and GH calmag. I've not had any major issues I've had progressively bigger yields. Successful from clone and seed. I'm looking to simplify the nutrient...

I'm wanting to build an auto top off tank to add to my dwc. I have float valves and a bunch of stuff to use for it and have an idea in my mind. I just want to pick some brains. If you have something like this let me know how you did it. Thanks

So I just got my water quality report from my water company and was wondering if someone can look at it and see what they think. I was hoping it showed everything that's in the water but looks like it just shows the stuff they put in it to disinfect it and any contaminants (if present). Just...

So I've always had dedicated grow rooms but I had new hvac and work done in the basement so for the sake of not getting caught I ended up tearing the rooms down. So I won a 4x4 mars 20$ (mainly used it for drying) and now I scored an 8x8 vivo for 100$. My question is what is the best way to...

Idk how much they are new but sure someone knows. I just scored a vivosun 8'x8' for 100$ brand new in a factoy sealed box. I'm cleaning up an area for it now and will be setting it up shorty. I'll post pics shortly

So yeah I had a little to much fun last night and ended up falling asleep b4 my maintenance time. I woke up like 10 min b4 lights out and ran to check on everything real quick and one clone had drank all the water in her cup and was drooped all down. You think she will come back? I put water in...

When you first take your rooting cutting and put into dwc bucket what EC is a good first ratio? I use gh trio. I looked and looked in my note book and can't find what ec I used so need you all

Man I thought O.G. was musky until now. I opened my tent popped my head In for daily inspection and she was beautiful then it hit me, musky bad musky!! Came out for fresh air, went back in and took a big smell and I just knew I was getting root rot. My Skywalker had a musk in early flower also...

So I love science but never liked chemistry so I have no idea how I should do this lol. I got my veg ratios that I am comfortable with but not sure what a good base line for flower nutes is. I use GH trio and for late veg been using 5ml/gal. of each plus calmag @3ml/gal. Just trying to get...

I figured I'd give it a try and see if it's something I want to do regularly. I Don't have a smaller more adequate spot to work so gonna have to use the tent. I think I'll be able to keep the environment decent enough (hopefully) just not sure about light. I have a 400w turned down to 25%. Could...

First I'm not a plumber nor do I know much about fluid dynamics, but I am a handy man and know how to do stuff. So my question is if I have to go Thru a wall with my return line and it has to go over 2x4s can I put a bump out in it? I made a drawing for reference. Don't laugh to hard at it but I...

Trying to get opinions before I change everything around. I know I've read about someone doing it before but don't remember the outcome. Does a submersible pump have to be submerged? I know they are made water tight so water don't get into the electrical part but does that make it why it has to...

I've not had any deficiencys in last 3 runs and I do the same all the time just wondering what I got going on here. Dwc, gh trio nutes. Strain is gg4. Tap water is 50-60ppm.

Look what I found while chopping.I had a feeling she was traumatized and would herm. I'm not upto snuff about pollination and all so if a fem skywalker og seed has seeds in a few of the bracts during harvest what is that seed? Fem or dont know 50m/50f? I didn't see many nanners but there were...

I'm in a very bad situation and can't get the info I need. If your a hvac guy and willing to give some advice let me know and I'll fill you in. Thanks and sorry if it's not posted in the right place.

let's go on an adventure together. I recently won a @Maxsisun #MG3000 in a giveaway here on riu and I'm supposed to test it out. I don't have any seedlings going at the moment but do have my first GG4 in veg. She is in a 4x4x6'8" tent and until now had my experimental veg light on her. It's...
