starting DWC scrog grow soon

[allhailthebud]

hey.

 

well, im sick of soil allready, the mess, the wrong pH soil, blahh! everything!

 

im going to grow them a little bigger, and take clones, start DWC.

 

im going to have 2 plants, DWC scrog. im looking to get about 20oz out of a cupboard size 160L X 49W X 170H CM. - this grow will be the replacement for this years failed attempt at an outdoor grow, even though its pretty late in the season.

 

ok, ive got 1 air pump, twin outlet, im guessing im goin to need another ?

 

400w HPS & 130w CF. if the plant is suspended in clayballs, there is no need to water them is there ? the plant draws the nute solution straight from the tub right ?

 

when i take my clones, when putting them into the DWC (to get them rooted) should the bottom of the stem be in the water ? and as the roots grow should all roots be in the water ?

 

also im going to need a truncheon thingy ey.. ?

Mate, you sound like a man after my own heart

 

Anyway - Allhail mate.

I responded to your PM about your soils, take alook through the thread I sent you, explains alot about soil growing - notice I never mention adjusting the ph of your water once? Medium ph is alot more important in soil than water ph (I don't bother adjusting mine).

 

Anyways... DWC, lets answer ANOTHER round of your questions... I'd suggest you read a few more grow diaries after you get through this response

 

ok, ive got 1 air pump, twin outlet, im guessing im goin to need another ?

 

Depends - how big is your container? You don't mention it's size.

25ltr containers would easily be covered by dual airstones from a twin-outlet pump. I run two pumps in my container each with dual airstones, but my container holds 60ltrs of water once filled to 1" below the netpots.

 

There are a number of good discussions here on DWC and air, browse through the forums and pick some out.

 

400w HPS & 130w CF. if the plant is suspended in clayballs, there is no need to water them is there ? the plant draws the nute solution straight from the tub right ?

 

That's correct, providing the plants has roots IN the water you don't need to water them from the top. If your clones are not rooted outside the netpots when you put it in your container you will need to top-feed until the roots hit the waterline.

 

when i take my clones, when putting them into the DWC (to get them rooted) should the bottom of the stem be in the water ? and as the roots grow should all roots be in the water ?

 

See my post above.

When starting new clones without long roots, I think keeping the water-level 1" or so above the base of the netpots is a good idea (just make sure it doesn't touch the rockwool). Once clones have roots out of the netpots and into the tub you can drop it to about 1-2" below the netpot.

 

also im going to need a truncheon thingy ey.. ?

 

If you're using anything except an A and B part nute - then yes.

Additives like boosters/rootzone protectors change your ph and EC, if you use anything but plain old water and nutes you are best off having a truncheon when growing DWC.... that is to say, it's not impossible to do DWC without one, but they do make life easier.

From you you said i gather you just want to take clones from your plants and root them in your dwc container.

Yesy you can root them like that if ur solution is just plain water. Snd yes the stem has to be in the water. 2 - 3cm in the water

[Guest jjfto]

20 oz with 400w hps?

You will have to veg for like 2 months even then you will need a good high yeilding strain.

True but allhailthebud had a very bad time - seeds puchased at premium price + bad experience first up. He is going indoors after a screw up with genetics & medium.

 

I have to give a hand even if it is more advice and he can go from there (I'm an avid 'search page' user) as I don't like peeps in this situation. For what he asks about the clone and how deep to put it I would not think he would find the answer to the Q within 7 days. A post would get him on track much quicker and may have resulted in him posing a Q anyqway.

 

I have plenty of time atm too. :smoke

 

allhailthebud asks:

 

1)  when putting them into the DWC (to get them rooted) should the bottom of the stem be in the water ?

 

Soz I don't know the answer to this one in DWC. I will leave it to some one else. -at a guess it would be better to keep it 1" in the water so as to include an internode which the roots will shoot out from.

 

2)   ok, ive got 1 air pump, twin outlet, im guessing im goin to need another ?

 

You could get away with 1 pump if you had to. enember it works on 'back pressure', - keep the pump above the level at wich you are delivering the air to & keep the delibery hose as short as possile.

 

3) also im going to need a truncheon thingy ey..

 

Yes it would assist you. You don't need one and the same goes for a PH meter.

 

I have both but in times like recently when my PH meter decides to pack it in on me fotunatley I use nutes which are "buffered" to bring the PH to 5.8 @ EC =- 1.8 - 2.0.using the dose give on the lable - real handy! So you can get away with no assistant devices if you want. expereience is the key here.

 

I got aa Q for you allhailthebud ! You problem I reawd on you post. Did you definately confirm the origins of the proble to be PH or was it he dreaded fungus? :scratchin

 

3 - 4 post beat me amd may be I got you mixed up too - hashed out ATM

 

Grow well allhailthebud & goodluck with this venture. :thumbsup

hey,

 

well, im not too sure of containers, but im thinking 2 big containers maybe 4 plants under 530w..

 

ill be doing some reading on DWC tonite, and prolly going to get all the stuff ready asap.

 

whats better out of thease clone rooting dillys - powder or the gel/liquid ?

 

well, based on a DWC scrog grow, on OG which im sure plently of people have seen, 150W in tiny cupboard getting roughly 4oz. I hope off 4 plants i could get 5oz each, but no-one ever gets what they want on their first grow :scratchin

 

NITRAM - not quite sure there, well. it seems to be the soil from what i figured. 5 plants are in 9ltr pots. 2 of thoes pots contained 100% potting mix - there the yellowest plants. other plants mixed with a bit of other soil/perlite/vermic are greener, and ones with less of the potting mix are healthier. However, i went down and got some blood &bone and some better potting mix this morning. repotted the yellowest plant, there no-where near dieing, there very still much alive but just yellow and looking weak. i also relised i was over-watering them due to droopy leave's, and i didnt water them for 1 day and when i looked at them that morning they were all standing up nice n spikey lookin'.. so i only give them a water once a day now.

 

also, im going to get some bigger fans, im only running 120mm fans now, and there too noisy and space consuming.. i need to get a bigger fans, and run it on a speed controller.

 

remember, this grow is stealth, and noise could be the only thing that would blow it. :thumbdown

[EDIT]ok, ive done some searching, and can someone dumb this up a little for me ?

 

Now you have been growing for a week, and some of the water has been taken up by the plants,

some has evaporated, and now your res is at 947ppm. You need to get your ppm from 947 to 1330.

Here is the equation:

 

((target-current)/target)*8 mil's per gallon*res gallons = micro double this figure to get bloom mil's

 

Example:

((1330-947)/1330)*8*22

(383/1330)*8*22

0.3*8*22 = 53 mil's micro

 

53 mil's micro double that and get 106mils bloom. So 53micro and 106bloom to add back to your

22 gallon res to get you from 947 to 1330.

You probably should work on roughly 0.5 gram per watt (optomistic), so at 530watts, you would be looking at roughly 265 grams = say 9oz.

only give them a water once a day now. Hay :thumbdown

 

 

I have 20 Lt pots and water every 2-3 days (dpending on rain/heat/sunshine ect)

 

I think watering every day to "run off" in 9ltr pots could have been your problem then. Aerobic (spelling?) medium and can lead to root rot. In your goiing get you have to let the roots dry out as there are microscopic (hairs) and are needed. Let your pots dry off well.

 

so your still giving them a go them ?

 

goodluck allhailthebud

hey

 

nitram, going to grow them a bit more, prolly few more weeks, so i can get a few clones per plant & then start DWC.

 

i was wondering, 5 of my smallest plants still in small pots, could i just cut like the plant in half basically and start that as a clone ?

 

how far should the lights be from my plants ?

 

ok, im prolly going to use 3 x 45L round tubs. 3 strains. - marley collie, white skunk, skunk 1 and im going to get another reflector for the CF - would the CF best be mounted sideways, or handing down ?

 

im going to have 1 screen mounted accross the whole cupboard, not sure of height away from plants yet. would it be best to use a plastic or metal screen ? and how wide should each hole roughlt be ? be enough to fit a fan leaf through ?

 

thanks guys
