Hydroponics

Looks VERY HEALTHY!!!

I have a question. I've been looking around, reading post, and threads and still no luck. I have a growing bible.. It doesn't specify.. I almost feel like a noob for asking.. Hell, I wasn't about to post a thread with this question.. But.. Can you use the same nutrients for hydroponics that you can with growing with dirt? Or would I have to go and get some different nutes? I wasn't quite sure on this.. so if anyone could help me with this that would be awesome! Thanks!

Fertilizer manufacturers assume that the plants are getting trace minerals / elements from the soil.

Nutrients have the big 3, N P K, but also have the trace minerals that the plant needs for healthy growth.

You can use a fertilizer with lots of supplements and guess work, or use a complete nutrient and save yourself time and heartache.

Okay I see what you're saying. So If I go to home depot, could I find what I'm looking for?

Hey guys, I have my sprouted seeds growing in rockwool. My hydro setups are general hydroponics waterfarms filled with hydroton (top feed system)

my question is, how often should I water the system, will the 1.5" rockwool cubes soak up to much water?

Thanks a bunch

I have Miracle-Gro Tomato Plant food for my house plants (some hydroponic).

It is NPK 18-18-21. It is designed for soil.

But reading the Guaranteed Analysis, it also has Magnesium, Copper, Iron, Manganese, and Zinc. These are very important trace minerals. So it's good.

But Cannabis seems to need these traces and more and in certain strengths. You can get by with something from HD, but it won't be your best grow.

I am going to investigate Jack's Classic Plant Food by J.R. Peters. I've heard some good things about it. And HD doesn't carry it...

Well my question was.. can I use it hydroponically? I know it's designed for soil.. but I need some nutes for my hydro set up.

is there chunks of fert. left not dissolved in the water? if your water pump can take it, its all good im prety sure...i use FF Grow Big formulated for soil, hydroponically, and it seems to work fine..

on a side note, iv noticed that my PH is ALWAYS at 6.0, nomatter how low i take it, it will end up at 6...does anyone know if FoxFarm has a PH stabalizer in the Nutes?? either way iv just stopd fuckin with the PH and things seem to be fine...kind of weird tho

hello I need a question answered before I attempt the operation I am going to preform. First all I have different strains growing in a 24/7 drip table but the roots need more space and more of a downward angle some of them are drying up because they cant get enough water. This has put an over all stunt on all the growth, the plants are in the first week of flowering and I am wondering if I can transfer them into a dwc system to improve yeild? will this hurt the plant transplanting it into a different environment? I am just going to wait a few more days untill I can see the females and males then I will put the fems into a dwc ? any one think this is bad or good? right now my plants are a foot tall but they should be way bigger after two months of veg and the root systems are petit. thanks

i have a 5 gallon bucket cut in half....with 3 plants about two months old...proper exhaust and oxygen along with a 30 gallon water pump and a 4 inch airstone but you guys say change the water every one to two weeks right??? every time i mix my nutes and ph down to get my 5.7ph and in an hour after i change it the ph jumps up to 7 like it used all the nutes???? i've been using 5 drops of ph down and about two teaspoons of fox farm grow big hydroponics... y is this happening??? heres some pics but help would be appreciated...thank you

Hey everyone,

Im new to growing and have a couple of questions..

Im looking to grow around 3-6 plants with an Hydroponic system..

What kind of lighting shall i use? do you guys recommend MH or HPS and what watts shall i use?

Also any other recommendations are welcome.

Thanks.

depends how much space you have and what you are growing in but you probably need a 400 watt hps light for 6 of them

What do you guys think about drip systems in general? I've done small DWC and also Ebb and Flows. I am considering 4 of this product http://shop.v-drip.com/cgi/display.cgi?item_num=V24 I have done really small 12 plant runs and I really want to run 4 of these under 2000 watts 2X 1000HPS) I'm a little apprehensive because I haven't done drip yet. I want to try it because I am wanting to go CoCo and also the systems are cheap and I don't have to go out and spend a shit ton to build up a new Ebb system. 4 3X3 ebbs would cost me $300 each these are $159 each so long story short is drip and CoCo a reliable way to go?
What I plan to grow is in my sig

Wow... I paid 80 bucks for mine.. all the way in Alaska...

I would look into maybe making your own trays of cash is really short... but I would deff. stick to ebb / flow...

I use 4 3x3 trays and LOVE it!!!! each gets a 600...

Just saying.. nothing wrong with coco or drip...

But MY personal choice would be to mimic Al B. Fuct's op with 2k watts...

Best of Luck...

Yeah that is exactly it I want to do an AL B grow. Everywhere I look 3X3s are over $300 per system plus a shit load of shipping. although after pricing it separately I get it down to (about) $155ea and I have to build tables, another $20 in build materials (I'm not good at building stuff but I think I can make tables LOL) and use Rubbermaids for Res.

Anyone else? please? lol I am anxious to sprout these seeds but I am waiting until I pull the trigger and order my parts. I got $2K burning a hole in my pocket but I have learned to ask first!!!

Well...

Here is what I got going right now... I've been "on a break"...lol.....



I made a square wodden "table" to support 4 3x3 trays... making SURE to support the trays from underneath... not just hanging from the lip... in time the flex will turn into a crack...

I'll take a picture of it when lights come on...

I use Rubbermaid Stock tanks... pais $100 for my 100 gal res in ALASKA.. where everything is way more expensive...





I like the white BOTANICARE trays.. buy them locally.. shipping them is a bitch, chances are they will crack... I pay $80 for the trays and another $17 for the fittings...

Here is one on the net for $85... but like I said.. buy it locally and save on shipping and hassle...

None of it is CHEAP... but you will get your money's worth for sure... I know I did...

Here's some older pics... Fuct style perpetual...

Have you read Al B. Fuct's https://www.rollitup.org/newbie-central/12071-noobs-if-you-fail-plan.html

It is an AWESOME post...

First off: Nice Bud Pron.
Second: haven't read taht link working on that now.
lastly I was stationed at Elmendorf in alaska it rules all.
Thanks for the information. I have a few Ebb and flow grows under my belt so I'll be fine doing Ebb and Flow.
I just wanted to get the most for the least invested but it might be best to spend on what I know and save the experiments for someone else since this isn't just about for "FUN" although it is "FUN"

watsup, been growin in soil, finally movin over to hydro. im settin up a ebb & flow setup, and i got just a 2 ft by 6ft by 8 inch deep plastic flood table. i got a few questions:

1) i plan to put them in rockwool cubes, starting seeds in 1.5 x 1.5 x 1.5 in cubes, then moving them up to 4 x 4 x 4 in cubes when they are larger. does that sizing seem wise? and more importantly, im kind of wondering does it matter if i put some other medium in my flood table besides rockwool cubes? i know i've seen some people using pebbles filling up the flood table and then rockwool cubes kinda buried in the pebbles, does it matter if i just put cubes right on the table with nothing securing them in place? will they slide around a lot when the table fills up, particularly in the seedling stages when im usng smaller cubes?

2) As they get larger and the roots begin to come out the bottom of the cube, do i want to raise the cubes up so as to keep the roots off the table, like dangling in the air? i was thinking about running a dowel rod or something through the cubes to raise them up like a half inch above the bottom of the table? wise? necessary? opinion? I don't know that much about what I want to do with the roots in my hydro set up...i just want best advice as far as how to avoid root rot and how to make sure they get maximum o2.

3) how often is good to flood my table? ive read that it doesnt make much of a difference how often there flooded so long as its least 1 time a day for a decent time period, opinions?

4) How important is it to keep my resevoir covered? and also, how do you best recommend maintaining a constant temperature within my resevoir? does the water need to just stay between 70-80 F?

5) and finally ph! im getting a ph buffered dry nutrient solution, and my plan is to just flush them every 7-10 days and make a new nutrient batch, will that be good enough to avoid any problems with ph? im not trying to buy an expensive ph tester, i was thinking about maybe just some litmus paper just to identify if the ph is the problem and make a new batch if thats the case...opinions?

thanks for the help and sorry for the long ass post, i am just gettin into hydro so i had a few unknowns...preciate it
