Milk jug for a Greenhouse?

So you have a small layer of rocks on the bottom, then the rapid rooter right? Your water is just splashing the bottom of the baskets so does it capilary up the small layer of rocks and then the rapid rooter absorb it off the rocks, or is it just barely splashing onto the rooter itself? The reason I ask is that I had made a single hole bubbler for my 2nd try at 100% hydro from start, only I used a rockwhool cube instead of the rooter. The net pot was just a jimmy rig dixie cup with a shit load of holes in the bottom. I put a cotton wick in bellow the rockwhool and when I botched the grow... or lack there of... the rockwhool was soaked like it had been sitting in water for days. The bubbles were just splashing the bottom of my "net pot" too. The rockwhool was frustrating as hell, but I do like a challenge.

As far as this grow is concerned, holy shit. Within an hour of putting the new dome over the plant it started growing again. Ive been so excited that I have checked it about 10 times today since. Every time I see change. Loading the dome with co2 has got to be helping too. Ive turned the dome upside down and blow 2 or 3 deep breathes down one side of it to force the O2 up and out the other side(since co2 is heavier) then quickly place it over the plant.

It did get me to thinking, could you put a cup of seltzer or club soda inside the dome and it last for more than an hour or so and output co2 for clones or several seedlings?

BTW are you transplanting that whole small net pot and rooter into your main grow system?

Yes... I transplant the whole netted basket into my water farm when ready. I let the water level in the bubbler brush against the basket about 1 cm from underneath. The airstone keeps the rooter moist. The idea is to keep the rooter plug supermoist during seedling stage. After about three sets of leaves I move the basket to my water farm and start growing with my HID lamp. I start the plant with a seedling mixed feed for 1 week and then flush the hydroton and mix early veg grow stage and flush after 1 week and move up the feed chart. As long as the rooter plug stays moist then the bubbler is doing its job. I put about 1 mm deep with hydroton in the basket... place the rooter plug and then fill the basket to the top with more hydroton. You will be soooo much happier with rooter plugs than rock wool. I hear alot about root rot with rock wool. I used the cup with holes method too but seemed to be more sensible to just fork out a few bucks for the real deal baskets since they don't cost much to begin with. You can get a bag of like 30 plugs for around 17 bucks.

Ok, day 11, I am cursed. I didnt have this much trouble on my first grow ever. The slight discoloration from before has turned into prominent dark spots. There are even discolored parts on the tips of the new growth. I see roots in most of the holes in the bottom of the cup so the roots seem to be doing good for the actual size of this little hellion, but what is causing the brown? I flushed it 2 days ago with 6.9 phed water to try and bring the run off up as per Stinky's instructions in another thread. Im afraid to water again to test the runoff until it actually needs it. Im ordering rapid rooters today. If this thing goes south Im going to be ready for another approach.

I have no clue as to what the browning is man. :wtf:

Looks like a job for stinky.:thumbsup:

Just remember next grow get some rapid rooters with a tray and dome cover. Cannot go wrong man! Soak those seeds in paper towel till you see the taproots start showing and then put those babies in the rooter taproot down. Cover them and water the plugs daily to keep saturated with a nice bright fluorescent bulb over them. They will grow real fast. :thumbsup:

i did order a proper dome with adjustable vents to go with the rooters. I didnt get a tray though. I will find something plastic that they will fit in comfy and put under the dome. I just feel lame putting like 2 rooters in a 72 hole tray I went ahead and got some 3" net cups too. Im guessing use the "tray" and dome until the tap root comes out, then put it in the bubbler with straight water until the 2nd or 3rd leaves, then the WF with its first 1/4 strength nutes. Im about tired of getting shut down at the "easy" part. Not a lot of posts out there about seedlings f'n up at the stage mine are. Im starting to wonder if something is wrong with my tap water or something. Im afraid im going to have to start another post to get stinky's attention.

I can't see close enough but it looks like you are heat burning your leaves.
