Hydroponics Question and Answer NewGrowth Style

[NewGrowth]

Sup Man!!

I just upgraded my grow room!! Its really sweet now. Fyi you were right about the advice u gave me about my fan being able to cool my 1k and a pull plenty of air through the carbon filter. I could easy add another 1k...

So now you can upgrade to 2k when you get a larger space.
Thats my count^^

Im still trying to find the right system for my 4x3 aera. I wanna find a medialess system where its easy to change res and only need to adjust solution by weekly. I still may go ebb and flow but im trying to avoid bying stock in rock wool. Just seems like a waste of money to me. What ever system i choose the res will need to be beneath the plants so i can get the most canopy space for my area. Any guidance would be appreciated.

If you want a pereptual harvest like you said before you will need ebb and flow. Unless you have cash to spend on multiple Aero/DWC/NFT set ups. The problem is you can not obtain the same plant density you can with flood tables.
You could one large harvest in that space with an aero stadium however.

Do u think T-5's are worth it? They seem so expensive for flouros.

Wow I was really confused by that one

No T-5's will never produce dense buds like HID's and even for veging will not provide the same rigorous growth rates as HID's.

Peace FL!p

Listening to Marley here just blazzzzzzed

I was just gonna use the T-5's for seedlings and clones instead of the 400w mh. I just love how fast my veg is with it. Costs me 20 bucks more a month tho...

Lol no floro flowering here.

Yeah that should be fine but I don't think T5's are worth the additional costs for clones and seedlings.

Good to hear bro

Ok so if i were to do a flood system do think if i used the 4x4x4cubes i would need to use slabs too? Flowering smaller clones...

I was hoping just the big cubes packed a tight as possible. Good till harvest you think?

Im gonna save the media less system for when i have more time space and money.

Im also thinking about using a deep rubbermaid for the res and a shallow rubbermaid tub for the flood tray. Do you think i could just put a peice of pvc on the outlet of the pump and drill a hole so the pvc sticks out of the shallow tray for the flooding. This way at least im thinking i could just lift of the flood tray of the res and set in on the floor and move my res out for changes and maintence. See any problems with this?

Im gona need a special timer for flooding arent i?

Hi everyone
can someone explain what the lucas formula is please.

Hi NewGrowth,
Im having a silly newbi problem, after germination I place the seeds in rockwool and they always die why am I doing wrong?

At first I discovered I was watering (PH at 5.8 & no nutes) too much then I tried misting but there were no changes the temp in my heated propagator is at a constant 28C & humidity is at approx 75-99%
Now my newly germinated blueberry seed is in root riot and would like any advise, opinion or otherwise which will help grow this seed.

It's hard to get that kind of plant density in a small space unless you have C02. Use 1gal pots (not net) and hydroton without C02. With cubes you will not need slabs unless your plant height exceeds 12". Then you can anchor them with string to prevent them from falling over.

Im gonna save the media less system for when i have more time space and money.

The cost difference is quite large.

Yes but you will have to line the top rubbermaid so that there is no drainage in between the spaces of the rubbermaids.

Yes but if you have multiple flood trays you can wire them to a single multi tap timer. Pumps do not pull a heavy amperage load like lights so they can be wired to a single timer.

What he said

Hi NewGrowth,
Im having a silly newbi problem, after germination I place the seeds in rockwool and they always die why am I doing wrong?

Could be many factors starting with most likely: 1. Rockwool was over saturated
2. Rockwool was not properly prepared ie sterilized and soaked to PH adjust.
3. Environmental conditions, high or low temperatures ect.

At first I discovered I was watering (PH at 5.8 & no nutes) too much then I tried misting but there were no changes the temp in my heated propagator is at a constant 28C & humidity is at approx 75-99%

Sounds like the rockwool was not sterilized with H202 prior to planting

Now my newly germinated blueberry seed is in root riot and would like any advise, opinion or otherwise which will help grow this seed.

Sounds like a rootzone pathogen you may still be over saturating the rockwool. Maintain your humidity at or below 40% and allow the rockwool to dry a bit between waterings. Remember to pre-soak your rockwill with a Ph corrected H202 solution. If this does not solve your problem you might look into sanitizing your growspace before re-planting.

Good thread.. Only thing im a little confused on is measuring the ppm... Well I know how to measure it with my tds, but as in measuring the amount of nutrients.

When I measure, do I measure the ppm of the water before adding nutes, than after adding nutes and subtract the ppm of the base water from the new ppm from the nutes?

E.g Base water ppm = 250ppm... I add my nutes and the new nuted water ppm = 750ppm.... so 750ppm - 250ppm = 500ppm... 500 ppm being my amount of nutes to moniter, or do I moniter the entire 750?

Any help is appreciated

Yes subtract the beginning PPM from the total to get nutrient PPM.

Nice! I just learned something. Thanks for the input NG.

Why does the waters ppm not come into play?

Little to no nutrient value in tap water the PPM reading is mostly due to calcium.

 

[hamburger]

Ok thats what I started doing right when I got my meter, however my ppm went up after a day, this would mean add less nutes to the water?

Took me forever to find this I was to lazy to type it again
1.Water level drops PPM goes up: Drop your nutrient strength in relationship to the PPM rise.
2. Water level drops PPM stays the same: You may be able to fine tune you nutrient strength, if growth is vigorous leave it alone.
3. Water level drops PPM drops: Raise you nutrient strength in relationship too PPM drop.

 

[hamburger]

Cool, I just went from 1/4 strength to 1/2 strength, guess they werent ready yet.

Btw: I am running a top feed system with hydroton and I have my pump turning on for 10 minutes every hour to hour and a half.. Is this suitable.

This is fine just monitor plants for any visible signs of overwatering. And never water during lights off or right before lights off.

 

[hamburger]

Ok great, I am running my lights 24/7 at the moment so no worries there I will probably be back for more help sometime. Thanks.

Sup NewGrowth!!

Just ordered a 3x3 botanicare flood table! I got a 396 gph pump with 3/4 fittings and tubing. I haven't decided on a res yet. The botanicare one is too pricey. I was thinking just a 20 gallon rubbermaid. I wanna flood 5-6 times a day. Do you think ill see much drift with this size? I dont wanna check every day!! im gonna run 1300ppm whole bud stage. Gh lucas formula with H202 @ 35% Kool bloom powder 6th week..

I wanna use grow bags with hydroton. Planned on using 1/2 gall bags. I think the bags will give me slightly more room for roots than the tapered 6" square pot... Thoughts?

One liter per plant is a good rule that Al B put out there, I did not even know I was doing that when building my set ups. I would just estimate the reservoir size from past experience. When I looked at may journals I found that I was running about 1L per plants.

Never used grow bags with hydro, unless you use coco-coir. I would not use coco on a flood table though. I would think a grow bag not stablize the roots as well as a standard pot. I just use standard one gallon black nursery pots. A plant of one foot in a SOG should not have any problem in a 1 gal pot.
