I just started flowering.I can’t show pictures because I don’t have a memory card.Two of the plants were pre flowering.

The setup I, have is a rubbermaid thing and some sometimes.Pretty simple.

I have, new root growth that’s doing really well but some of it has formed algae.

I think Ill try and buy that system.Thanks for the link.

Im running Blue northern Skunk #1 and mean purp.Using general organics.I taped up the container because it was clear.That has helped with the algae.

I have the plants in cups and pots and the roots run down inti the water.The pots are filled with coco coir.The root systems in the pots are great with new root growth starting in the res thats algae free.

Fed them yesterday with Biothrive bloom bio root bio weed bio marine and camg+.I dont have a ph meter but these nutrients are supposed to be ph buffered and honestly Ive been doing alright going by eye.

I need a ppm meter a ph meter with ph up and down just in case.I also need a res temp gauge and a hydrometer.Im doing good without all that somehow.

These planta are doing good on alot of luck thank god.Ill add pics when I get a memory card.

Thanks again I just bought that system you showed me.When it arrives and I get it up and running hopefully ill be able to show some pics.

one of these kits is REALLY easy to make yourself. Do you have a pump for air with a fishtank stone oxygen diffuser on it, mandala? I haven’t seen many problems with algae in oxygenated tubs…..

I have notice that with alot of dwc systems alot of brown roots.

Yes I have two air pumps with 4th inch airstones.I think the algae was due to the container being clear.I need to buy a hydrometer a ph tester with ph up and down then I need a cheap ppm meter.Ive been doing good going by eye and stuff but I seriously need all of that.

I hand removed as much of the stuff of the roots I could.The main root stztems are in coco coir with only a small amount of the roots actually in the resevoir.

What do I want humidity to be at?

50% is about the best to keep it at then if your flowering indicas and you get really big buds cut it down last week or so to prevent mold id you have mold fungus problem but %50 is about right with no problems. Just dont get below 40 anything below that is too dry imo.

^— Mold will get ya sometimes if ya wait to long…so I hear! ^_^ Good luck….and smoke me out one day!

Containers must be light-proof or algae will grow. Water temps need to stay below 70degrees or bacteria will grow. You don’t want either.

Wow. Thanks for the link, Dub! That setup is sick.

It does kinda look like a bunch of car batteries hooked together….. but that makes it even cooler. LOL

You can see my pictures on grasscity.They are in the indoor grow journal.
