GT205 NFT setup and fertilizer questions

[Z-Beeblebrox]

I had forgotten all about the air stone, because I was already told it would be a good idea. I think I'm gonna go down and buy a pump right now.

As for H2O2, I figured how it will effect my bio balance. I don't keep things sterile. But I will try to read up on it now.

The Amnesia is regular seeds, and I'm hoping to get 2 good females.

I have thought about building a little motherplant/clone cabinet, since I can see the need for some optional growing space so I can have big strong clones. This should also increase my growing speed with some weeks.

 

[Z-Beeblebrox]

I just added a double air pumps and now both reservoirs has an air stone bubbling away...

Any treads I can read up on using H2O2 in NFT? How much would it benefit vs. the negative impact on beneficial?

 

[Scrogerman]

Depends, with or without bene's/organic addys, you cant run both ways. So Id go 0.3ml-p/l 17.5% H2o2 with mineral based regime(upto 0.5 mls/pl max), 2 days on/ 1 day off, or 2 days on 2 off,application every 24 hours, ive even run it 24/7 with execllent results myself. the visual growth boost is very obvious & i highly rate H2o2, certainly increases nute uptake without doubt. Just watch you dont get appliaction happy with it, as it can be overdone. I like using it all through Veg & first couple of week of bloom if im gonna be adding organic boosters, i drop it then(NFT). Nice to have on hand if anything goes wrong. Its not hard to switch back.

I didnt notice anything organic in your feed, so you should be good with it man. mineral based nutes, PK & H2o2 & id say your rocking bro!

Big Clones=excellent idea, as is the airpump(just watch ya Res temps)! G'Luck!

^^Scrogerman. Thats some good advice right there
I could'nt have put it better myself.

 

[Z-Beeblebrox]

ok - so I got some 10% H2O2.

The reservoir is 20L so if I dose 10mL each day would that be too much?

 

[azad]

10ml per 20L would be ok,but i would'nt add daily,maybe just 2-3 times a week at most,but thats just my opinion,not based on nowt...cheers

 

[Scrogerman]

Yeah man, Cheers Azad.
2-3 times a week is fine for sure. H2o2 dissipates/breaksdown totally within 24hours(dont add before 24h though), why i mentioned that application rate. prolly dissipate even faster running airpumps id of thought.
The lower the concentration of h2o2 the more stabilisers it contains, 3% - 10% for ex. I wont use anything lower than 17.5% concentrate, ideally the 35%. More benefits running a 'Dead Res' with h2o2 than running bleach anyday.
0.5ml/pl of the 10% is fine id of said, go a bit more if you wanted.

Oxy+ i use: http://www.growthtechnology.com/liquidoxygen.asp (17.5%)

Liquid silicon is another quality addy ime!: http://www.growthtechnology.com/liquidsilicon.asp
Been using Budlink for last couple of years but im trying 'Potsil next.

very clean set up ,,,nft is so easy and gives great yields ,,i run it for years ..

a few tips ,
2 plants max in the 205 ,they will soon fill the gaps in the first 2 weeks of flower ,this also stops the root mass getting too big for the pump flow

no need to run the tank whilst vegging ,just hand feed till there is an
abudance of roots out the 4" cubes then put on tray ,then put straight in flower or flower b4 u put on tray save ripping out cubes if u find males

use an airstone or 2 in the rez ,works better than h2o2 in my opinion



refresh tank every 7-10 days

enjoy hassle free growing

Hi Haze

I came to the same conclusion about only using 2 plants, with all the trouble these males/hermies have given me.

The plan for the next grow is to use some big clones vegged in the big grodan cubes, and then go straight to flower with only 2 plants.

Right now I have 6 regular Lalandia 2011 Amnesia in big grodan blocks under 12/12. I have an airstone and have just added 5mL H2O2 to the reservoir.

I haven't been able to take clones yet, since I need to build little cabinet for mothers/clones.

 

[Scrogerman]

Dont agree with you on all points there Hazy but whateva works, H2o2 & mineral based nutrition kicks it in NFT everytime!

those 205's are tiny & topping off the res will become a daily occurance, thats a pain with the little ones, 2-4 plants is spot on! just reduction in Veg time imo!

G'Luck!

 

[Scrogerman]

I ran 8 in the 424 last time i did an NFT tank, Big Scrog:



Amazing what you can do with a little NFT tank & that grow was a fk-up(my apprentice fk-up), still, somewhere near, just a shame on the strain selection also.

 

[Scrogerman]

I think its imperitive you have either proven fem's(ideally clones) or fem seeds to start off, try mixing reg seed with this kind of Rig & its a fk-up to say the least. NFT mostly rootmatt! Reg seed plants need sexing first or its a fk up.

 

[Z-Beeblebrox]

Agree - but for now using reg. seeds is the only choice I had.

I have a build-on cabinet in the drawing right now that can be fitted on to the right side of the cabinet. This would be 400x500x100cm wxdxh with a fan blowing into the left grow room.

 

[Scrogerman]

yeah of course regs this time beeb,
(but for new growers especially)I was just saying its a good idea to grow to(in future) & presex your reg seed plants before progressing with your NFT, & letting a large rootmatt form with your fem & male seedplants mixed!.
Its a fker im sure. NFT is for fem seeds or Clone growing only bro(by rights)!(never mixed in a tank/aquaduct like that)
Nice, ill be interested to see your add-on build, your builds are very neat n tidy!

With Reg seeds, Presex first, take cuts off all fems*(3-7, or 5/5 or 7-3 etc etc), number,grow out n keep the best. 2 times this has happened to you now. enough id say. id be really sorry if i didnt point this out & it hapened to you for a 3rd time. id say the same to anybody bro!

G'Luck!

That is killer.real nice work!!
im too lazy, i could never run that style.

 

[Z-Beeblebrox]

So this is the expansion I have planned:

In the top there will be a 40cm high room for cuttings. I have a propagator that can be re-build to a bubbler - Would that be a good idea?

In the bottom I have planned a space for some mother plants, maybe 4 different - but since I have no experience with them, I wonder what growing medium would be best - low maintenance of course. Would a bubbler work too or should I get some airpots and use soil?

Hi,
you should have a look at https://www.icmag.com/ic/showthread.php?t=31919 , a good guide to keep moms in small spaces. i keep my mum in soil. makes for less work.

if you get a propagator get one thats heated. roots like to be cosy. with cuttings I give them a dip in a rooting solution and stick in rook wool and hand water till transplanted to nft. normally takes me about 2 weeks to grow roots out of small cube and another week to get the roots out of the 7.5cm cube.

and here is a pic of my current babies, the stretch got away from me a bit and plants gotten a bit to high, having problems keeping the temps low enough at the tops of the plants, less veg in future.

also i had an air pump and stone in my res this time, this saved my ass as my pump got blocked for a unknown length of time, the plants where fine due to the air stone keeping the water moving and oxygenated. lucky i lost the air hose to my pump and had to add the air stone, will always use one in future as the extra oxygen makes a huge diff and make a good backup if you pump stops working.

Also got to test my cf truncheon, discovered it can take up to 2 minutes before temps equalize and you get a accurate reading, the higher the cf the more this matters. on first attempt to test truncheon i managed to get a cf of 10 instead of 28 lol. so when using cf truncheons i recommend sticking them in the res for about 5 min to get temps equal before taking reading.

would suggest that you just use the veg room for cloning and keeping mums, when the clones are ready just move them to the flower room and veg them there till you ready to flower. you would just need another blue blub that you could switch with the red bulb in you flower room.

Will have another grow diary to upload in about a month.

Good luck.

Hi recon. Thanks for the suggestions!

 

[Z-Beeblebrox]

So - an update on the current grows:

In the veg room, 5 out of six turned out fem, so i had to toss one to give room for 4 plants. The initial plan was to use 2 plants, but since the growth seems very even for these 4 plants, I decided to use them all.

I have topped/FIM'd the plant before 4th node and the same with the secondary shoots.
The plants are beginning to stretch a little after I topped them, but with the scrog net in place its just a matter of bending them under the strings.

In the flowering room I had to take drastic measures to insure better growth of my Blueberry's, so I cut the Early Durban - it had suddenly stretched over 30 cm over the last 2 weeks. I did not have place for it, and it was beginning to irritate me.

But then the 2 Blueberry have more room to grow on - and can get more airflow and light.

The buds are getting a little frosty now and the smell is starting to get strong. Its citrus with a skunky scent. There are some good (Good, for a first run at hydro) buds and the side buds are plentyfull and quite big.

I'm looking forward to get some clones and doing a better run with these:

Sorry for the color on the last pics.
