hey rollitup longtime lurker first time poster!
ive been wanting to try something new and have been debating with myself about transfering from dwc (veg) to flood and drain buckets with coco coir..
i cannot find a single instance of this being attempted.
so maybe i can get some of your experienced opinions on it
i want to veg in dwc for 6 weeks and bloom in flood and drain with coir for 9
is this possible?

it can be done but it is not advisable because transplant shock would be high just as you are going into flowering, and I can't see the reasoning behind it, why would one want to do DWC and flood and drain at the same time? maybe this is why itg hasn't been attempoted

yes but it sounds like a lot of hassle trying to transfer a 6 week old plant into coco pots. Have you ever grown in DWC?? Do you know how big a rootball for a 6 week old plant will be?? Why dont you just do the whole grow in flood & Drain ? Then you will avoid any stressing of the plant.

beaverhuntr, this is exactly what i was thinking. its what ive been debating with myself, if i grew in dwc would the root ball be to large and matted to put it in coir?

and the thinking behind this is that the plant would get bigger faster in dwc for the veg cycle. then for the flower cycle i would like to have the benifits of a coco mix.

Nothing is too large you will just have to buy a lot of coco coir and big ass pots " The bigger the roots the bigger the fruits " it can be done and will be fine, it will be stressed out though I see more con's than I do pro's.. You have to take into account how big your plant is going to stretch once you put them in flower. Do you have enough room? The coco mix wont be beneficial as coco is still considered hydro we just call it "passive hydroponics" the coco wont do anything for the plant, it will just make it easier on watering thats about it and no weekly res changes.

ok so after a lot of research, reading thread after thread, asking people online and off.
im gonna try it.
still cant find a single person who has but everyone i talk to says do it.

this is going to become a journal that i will update from here on.
just one more curious question for you guys...
im going to run a sealed room, would it be a good idea to vent the lights (3 1000s) FROM the ac coming from the wall?

What do you mean vent the lights from the AC?? You mean you are going to vent all that hot air into the air conditioning duct??

no...


from, FROM the ac in the wall.
of course the ac wouldnt be on all the time there would be a fan but the intake would be the ac vent.
the exhaust is probably going to be a hole in the wall :P

i just read your thread and it doesnt look like what im talking about at all :/
what i see in your thread is going from HPA (high pressure aero) to a F&D system (flood and drain) with the medium being lava rocks.

i want to go from DWC (deep water culture) to an F&D where the medium is coco coir and hydroton with probably some helpful mix ins just for kicks.
both of my setups, being the dwc and the f&d, are going to be in 5 gal buckets running a staggered 3 week cycle with 9 plants every 3 weeks.

ntm you are running on t5s for everything
im going to be under 600w MH for veg and 1000w hps for flower.

Yeah I was gonna say you should just cut a hole in the wall or ceiling and exhaust it there, dont worry dude they sale those dry wall repair kits at home depot, lowes and wal mart for like 10 bucks...

You shouldnt have any problems I have seen lots of growers transfer mediums I have even taken a teen clone in soil , washed all the dirt off the roots ( delicately) and put it into DWC you will see some shock the first day or two but if your environment is right she should bounce back. She might look droopy the first day or two but if you do it right she should bounce back, after all shes a "weed" and can take some abuse.

im not worried about cutting holes....
im wondering if it is a good idea for the intake to the vents ( i need an intake and an exhaust for a sealed room) to come from the ac from the wall...

ac vent in wall -> light -> light -> light -> exhaust

should i vent through the ac??

yes thank you, this is what i was figuring.
i believe this might be the method that ive been looking for all this time.
it just seems like the best of both world imo.
ill keep everyone posted to see if thats true

you can try whatever you want, but also try to do side by side grow, in one you keep them in their original container (DWC) and the other you transfer to F&D, it is 100% sure that you are going to get more yield in DWC in the same growing period because they kept growing without losing any roots and didnt get any transplant shock...

i dont think the two days of shock at the beginning of flower will affect the yield by a significant amount.
as long as conditions are right when the transplant takes place i should be ok..
and i dont think im going to loose any roots at all.



but im still wondering.. can i vent my lights FROM the ac???


AC -> light -> light -> light -> Exhaust


good idea?

you will get at least 15% less yield by transplanting from DWC to F&D, I used to do it always, veg in DWC then transfer them to F&D, but I always gave them the first 5 days after transplant 24/24 lighting. then I stopped doing that because it is useless, but you can try and see for yourself.
your ventilation idea is good.

ok getting started here... soon to be making large update posts..
just wanted a couple more opinions.
im having trouble finding alternative mediums to hydroton for the flood and drain bucket system, very similar to ebb&flow
ive seen coir been used but im hesitant because of the mess it will make in the res..
any other mediums i should be aware of, ill probably end up using hydroton anyway. i would just like to explore all the options
