thanks so much mate, you're right, yesterday I left my kids vaporiser ON after lights where out, checked the hygrometer which was just saying HH, which means I clocked it, and my prize is, unhappy plants. thanks again aqua, when I received your like, im sitting here going, now respond, now respond, HE RESPONDED!! hahaha change your name from aqua man to THE GREEN KNIGHT!
Haha im just another guy man no green knight and I also make my share of mistakes. Appreciate the compliment my friend

humble too!! honestly though, I noticed the issue, did some googling, wasn't sure, you rode in on your noble steed and sorted it out first comment.
Mistakes are always made in experimentation, id say you've done more than enough experiments/mistakes to reach your level of knowledge.

Morning All,

Brief update and more questions.

Half way through week 6 now. Things are going ok. I have just completed my final topping cuts, I am pretty happy about that.

Now just let them grow for a bit, bring in the scrog net and hopefully time things well for flick and stretch.

One of the photos is just showing the 16 head count.

The other close up has a question with it. The plant receiving the most light has really yellow new growth (photo doesn't do it justice), a couple of other plants have this also but not as severe. I have recently bumped up the ballast to super lumens, I did also raise the light a touch when I did this. Is this yellowing good or bad?

Happy growing!!

hey mate, hahaha yeah it's not a common method but growing some traction from what I see. I topped a couple probably earlier than I should/liked. Two of them didn't have their fifth nodes yet and they're the ones recovering slowest, otherwise, yeah I like to chop them soon after the fifth has shown up, now I'm just waiting to have enough length to start tying them down, I like to get to that as early as possible too while they're nice and flexible.
Yeah that's home now until harvest.
Its my first time so I'm doing the crash course into indoor hydroponics/NFT, I've done ample amounts of previous research but as always nothing prepares you for reality, fingers crossed.
This and aquaponics intrigues me so damn much. I like the idea of constant flow for a million different reasons. Late to the party but here now! 🍿

Yeah, I have bought from them. If you need something they only sell long you can ship it to my dock and I'll cut it to size and send it on to you. I'm not too far from them. I got a bunch of 10' stuff delivered to make a microgreens auto feed system.
Damn man. This community is so legit. Helluva an offer. Hope it stands for anyone 😂

thanks aqua, ive raised the light and lowered one of the fans so the leaves get more flow.

any chance it could be a deficiency? Only other change of late is I gave the system a fresh water flush on Thursday for a few hours, also top flushed all the plants with 1L of water each. I matched PH and temp for fresh water flush, but really this has happened a day or so after raising light intensity, its only meant to be about a 20W difference from 600 to super lumens isn't it?

Thank in advance mate as always!!

No need to flush. Plants like stability and that includes salinity. Try to limit extreme changes if you can. A flush is only ever needed in soil.

Too feeding once a week will clear the hydroton and that all you nead to do

ok mate thanks, good to know, I've noticed I get the most growth when I'm at work for my few days, my own worst enemy sometimes, who ever thought being too proactive will work against you 😂

I'm looking forward to going back to work tomorrow 😂

more questions!?

@Aqua Man, so you've mentioned transpiration a few times, well this morning the penny dropped and I actually just finished up having a light read on the topic. holy shit dude, very important stuff!!

Yesterday afternoon I decided I'm no longer going to blindly dose my reservoir with fresh water using my EC as my guide, I decided I want to know how much water Im losing as I had a feeling I'm losing allot, with my EC generally/always climbing with my PH. Sometimes EC goes down while ph goes up, usually on the cooler days.

So anyway, I made I little ruler out of my tie downs that just touched the surface of the reservoir solution, I checked it after about 3 hours and I couldn't believe it but I was already loosing water. This morning I've had to add 1.5L of water to get back to the level I was at less than 24hrs ago. might be standard info for others but blew my socks off!!!

The article I read said that all these things ie: transpiration / evaporation losses can be calculated using environmental factors to fill in the equations.
I guess while I have my ruler in there I'll work it out myself over time, just wondering if there is a thread on this here already?
also whatever input anyone has is also welcome.

tent temps are 24C lights on - 18-20C lights off
humidity 38% lights on - 50-60% lights off
reservoir temp - 19-21C

Happy growing

sooo... shit got ugly week #6, pics included

I've struck my usual problem with indoors, messing with stuff too much trying to seek better.... outdoors is so much more forgiving, I guess Mother Nature balances my shit out for me....

I'm attaching a few photos to hopefully shame myself into stopping this repetitive behaviour.

So I made a multitude of mistakes this week from, unnecessary flushing the system, over humidifying, increased light intensity and I think the MAJOR one is a big nutrient change.

Last week I decided to give lowering the amount of A&B solutions and adding more supplement solutions to make up my EC, so I think I've run into a deficiency this week as well as not giving them good conditions at times. I clocked 100% humidity a couple of nights due to not checking timers and swapping plugs around. (probably too many bongs)

So I have returned from work after a 3 days and Ive had growth but colouration isn't better just getting worse, also my transpiration issues from high humidity look like shit on the fan leaves so I removed those. Prior to going to work I decreased light intensity, raised it too the top and brought a fan lower to give the plants more flow. Temps and humidity has been fine while away.

Now they have a fresh reservoir which another mistake I made last week is I didn't add stabil/osmos to the last mix and my ph wasn't as stable as prior. You also wouldn't believe my stupidity, Ive just worked out start of week#7 that the H&G nutrient chart gives you the amounts of A&B in a combined figure which I should have been dividing. So from my first mix in week one I had to dilute the shit out of my mix to get the right EC, and I've kind of been free styling it from there. I mean, could I have done anything else wrong? FML
So this reservoir mix, start of week #7, should be on the money, I added everything correctly and according to the chart and my EC landed spot on. Amazing how it works when you do it right.

Lets see how they go now.

shit week! but on the positive, learnt allot and they're not dead yet

So I took the HST too seriously and killed them. Root rot I found out after a couple of weeks of trying different things, until I pulled them up and inspected the roots as nothing I was doing was providing a fix. I know why and where I went wrong which is good. So rather than push shit uphill, two days ago I pulled them and pulled down the setup. Sad, but also exciting, my first NFT run taught me so much I feel I will return more knowledgable but also a bit calmer towards the approach, not so aggressive with changes and nutrients etc.

So far I have disassembled, cleaned, de siliconed and cleaned the NFT channels, new end caps arrived early this week, they went on last night and are drying.

what do you do when you need your wounds healed? Buy shit!! New tent and new LEDs!!

I am hoping to de worm all the issues out of the last setup which didn't help with acquiring root rot, more slope, making sure there are no dead spots and quicker drainage (more slope) also going to raise the baskets so instead of having 10mm gap between bottom of basket and bottom of channel I want to raise it to 20mm clearance. Bigger reservoir capacity, not by much but Im going to link up two tubs, one will be in and the other will be out. Also going to add a sight glass to the reservoir so I have a more accurate way to see how much plants are drinking etc.

Im going to make a stand for the new tent 5X5 to elevate the tent so I can stow all the shit underneath it and hopefully reduce the noise produced by equipment. Raising it will also allow me to get the NFT channels closer to ground level leaving more grow room but ill also have enough adequate fall for drainage back to the reservoirs.

Another big change will be no topping next grow, Ive ordered beans so next grow will be 3X gorilla glue auto, 3X dark purple auto and 3X bay burger, just put them in and let them do their thing will be the plan. I also think my initial setup of 9 plants out of three channels is very optimistic, I am going to give it one more go with 9 to see how it runs before reducing. Numbers didn't account for any failure last grow.

Anyway I hope all is well with everyone else, I haven't had a chance to catch up on what everyone else is doing as Ive been flat out trying to stop plants from dying, now its quickly getting everything back up and running while my beans are making their way around the world.

Happy Growing!!

Hey ive been growing in nft now about 8 years saw you got root rot problem. I recommend some good beneficial bacteria and enzymes product like mammoth p, cannazym, great white shark they battle in roots very good way against bad things, dont know what your nutrient line including. Temperature is key too with root problems. I only wash nft systems after round sometimes water sometimes some mild cleaning product and never had any root issues. Good luck with next grow! 🙂

Thanks for the advice hippi, great to see another NFT grower.

Im using H&G aqua flakes. Part of my problem with acquiring root rot is I went too hard on nutrients, I will definitely will be going under the recommended in the future, after the first grow I have a little bit of a tuned eye for happy/unhappy plants as well as too much nitrogen etc. I might add this was one of many problems which lead to root rot, I stressed them too hard with environment changes also.

I have three 1m NFT channels, one inlet and one outlet and all linked. I am planning on 10mm of fall per channel, plus about another 10mm fall for drainage between channels. So from channel one to channel 3 there will be about 60mm fall. what's your thoughts on this?

thanks again for stopping by.

sorry another one if you don't mind, Since they need to have quite a developed root system before going in what is your technique for raising seedlings before adding them to the main setup? I made it happen with the first grow but I don't feel its a fool proof method. Once the roots are exposed out of the rock wool things can get dicey.

Nutrient line seems good what i looked websites i think their roots excelurator and multi zyme would be good to prevent rot but 18c-24c is optimal water temperature and high temperature leads easily to root rot. Yeah and always go lower nutrients first its more easy to add more if needed. Ive been using these nft https://nutriculture.co.uk/products/gro-tank-nft system 4 different size (now i got 2x smallest 20l), fits my style well because only 20cm height. Btw i use Canna aqua vega, flores and cannazym higly recommend them if you want change sometime.

I germinate seeds glass of water takes about 2-7 days they have good tail then i put them 4x4cm rockwool. They hanging there in candybox usually with little bit tap water bottom of box about 1-2 weeks when i see little bit roots i transplant them to 7.5x7.5cm rockwools. They hanging there about 1-3 weeks (same candybox) sometimes i add little bit veg nutrient when transplanted into nft system. Usually i start germinating when im close to harvest so after drying and cleaning tent they have good roots already and start growing pretty fast after transplant in nft and giving nutrients. And i keep them only under 9w normal led all that time.

Hope you can understand my bad english. 😃 You can go growdiaries site and search hippyhemulen there is some recent grows if they can help little bit. 🙂

from what I understand H&G nutrients are good, there is potential for a nutrient swap in the future as I have been having some difficulty sourcing H&G products and have heard good things regarding canna, if its more readily available I might have a go. So you only use 4 nutrient products from veg to harvest?
cool setups man!! I stopped past your grow diaries, impressive stuff! Seems simple but effective and no baskets or clay balls, HA, nice!!
thanks for the germination guide, it all helps.

Yeah only 4 products atm, tested with only vega and flores and nothing special change cant see with eyes, zym seems help roots pretty good. Vega till about 2-3 week after light flip and then flores to end, cannazym full cycle when i put them in nft and pk 13/14 only one time when buds are starting growing size so about between 4-5 week in flower. I tried with whole Canna line too but zym was most worth to buy what i experienced, full line gonna cost pretty much. Only negative is what found about canna is i could want little bit less nitrogen in flower nutes. My tap water ec is about 0.3 and 8.5ph and i think you live in usa so there could be different tap water and it could make some difference. Ph down is good to have too if needed some nute lines dont need that, canna keep pretty stable ph 6. Ph and EC meter is good to have too but after you used same nute line long time you dont need them that much anymore, good to have if problem coming. I dont own any ec meter anymore after i broken one but i should buy one and ph i check about 3-5 per round but its almost always 6-6.5.

Simple setup works for me maybe im just simple guy. 😃 Grow style i kept almost same whole my time only 2 soil/coco grow and other differences are just sizes with nfts, tents and lamps. And yea good think with these nft systems is no pebbles or baskets just rockwool. Rockwools became pretty standard at industry grow in usa what i watched. Ask if you need help anything i try help how i can best, there is many more good hydro growers in forum but they run mostly sterile hydro when i got more "live" hydro. You need test different things and see what fits your style best and no scaring with failures they teach alot. 🙂
