Hi guys heres a few pics of my new setup...

more pics

Hi Code 10

8x3


Good size growroom

keep those pics coming as they go along

get a cover over the channels mate , roots dont like light

dont you struggle with them being diferent sizes / ages coz surly the want different ec 's . if this your fist go at nft then i think you will and get them lights down

Channell covered now, and i decided to put different sizes / ages jus to fill the thing up. ive had problems getting hold of clones but this should be ok as long as the feed is managed correctly. This is my first go at NFT this big, well this is my first big grow to tell the truth so any help/ input will be grately appreciated.....

Lights are now 18inches from the plants.


*had a few problems with my clones yellowing, is this due to problems with my PH levels? my current Ph level is around 6.3
take a look!!!

have the clones rooted well , they look real young . they should have a good root system before goin onto the table

My cuttings had roots comming out of there cutting blocks and I put them into my 3inch cubes and straight on the table. this has been done before and was fine. but now yu mention it i might take them out of the tray and put the back onto the flood & drain table untill they show roots in the 3inch cubes.

i would take them of the table

these are how i want my cuts for nft , they are 4inch cubes

i just soak them for 24hrs and they are good until roots show usally

yep defo makes a BIG difference if you have roots busting out of the big bricks before you put them on the tables, they start growing very fast if done like that, if not they just suffer for a few days untill they recoup..

What you needed to do was run the NFT pump for a few mins to wet the blocks then switch it off till the blocks get near dry and switch it on again for a few mins. Do that until the clones get a root system established in the capilliary matting.

The way NFT works is that the roots, once established, can take air and water as they grow thru the matting to take water/nute solution and grow on top of the matting to get air.

Your roots are still in the rockwool cube at present, which via the matting will be soaked constantly so the roots get no air, hence the yellowing mate.

I'm not the best at explaining things maybe someone will come along and do it better:)

just bumping this thread as it seems to be as of interest to me at the min. Im currently bringing up some seedlings as we speak i have transplanted them into 4" rockwool blocks and the roots are just starting to emerge through the blocks but i have them just sat on the floor of my tent with a 250w envirolight hung above and the roots are looking a wee bit flatend and squashed which im a bit concerned about but what the best method / system to get a healthy root mass to an acceptable level ready for transplanting onto the nft table ?

I was just thinking about sitting the blocks on top of a filled plant pot with clay pebbles and hand watering untill the roots a plenty full but the probs im thinking im going to have this this method is the clay pebbles will dry out to quickly ? any thoughts on this or idea's

leave them on a flat surface mate , the roots will curl round i used to wait untill the whole bottom of the cube was white

i used to take cuts earlier to prep them

Thats what i intend to do jiffa but im a bit concernd about just having the blocks sat on the bottom of my tent with the roots no where to go and open to the elements.

In the past I've stood the cubes on a couple of layers of capillary matting in a cutting tray, the roots are a little happier spreading from the blocks into the matting, (may want to cover this with black and white to stave off algae growth). I then just cut the matting with scissors and place the squares onto the matting on the table. (hope this makes sense!)

yes this deffo make sense but when you have 50 to contend with watering them is going to be a bit of a pain in the ass with black and white in the way

Try mixing a bucket of nutes up and just dunking the cubes about an inch into it then give a little squeeze out so they're not overly wet, not as good as individually watering from the top but after a while you get a feel for the weight of them and It's very quick.

they will be sweet like i said

yeah i think that will the best way as im not to convinsed that just pouring water over the top of the blocks and letting it just soak through is the best way to go i like to sqweese the blocks a bit so they dont be come water logged and stale i reckon your way will be easier pick 1 up dip it sqweese out excess water put it back and im hoping jiffa is right about just letting them sit on a flat surface to root.
