HI,

I'm a first time grower using an ebb and flow hydroponic system
I’m using drrockwool for my hydroponic system. I’m going to use a drip system for my veg room now and an ebb and flow for my flowering room when my plants get into the flowering stage.

I was inspired by the "green man's growing cannabis" on youtube.
I'm just wondering how many times the pump should pump into the rockwool (according to Mr. Green's youtube video, Mr. Green says three times a day, 15mins each time), Does three times a day cause nutrient burn or lockup? I mean, normally, the nutrients directions says, mix it with water, once every 7days, etc. So Pumping the nutrients into the rockwool 3 times a day is not correct?


Thanks for taking time to read.

It means nutrient solution (nutrients and water mixed in the correct ratio). Pure nutes will surely kill the plants in record time!! You need to check the concentration of the nutrients in the solution and make sure they are within the boundaries the plant requires.

I hope this is what you were asking. And I hope it helps!

Hi! Loafyboy,

Thanks for your promp reply.

I think what I meant was, after you've mixed the nutrients with water in the correct ratio, and you've put it in the reservoir container in a drip system, how do you set the timer? ( 3 times a day , 15mins each time is okay? )

I've learned from the Green Man's video(from youtube viedeo just type " Green man ", 9 videos will show) that 3 times a day, 15mins each time will be fine, but ... .according to the instruction on the nutrients I have says "once every 7 times (so is the instruction on the my nutrients tells me .



I don't know if the knowledge from soil grow is suitable for hydropoinc grow, but I'm just carefully using my common sense to try to figure if.... ...
using the correct ratio and giving it to the plants three time a day, 15 mins a day is okay and won't cause nutrient burns or lockkup??

The nutrients I have right now is a all natural Japan made nutrient (" ALL NATURAL" ,so it says on the advertisement, and I wish I had other options)

Below is the infor on my untrients,

saion-em - Agriculture
( B and Q store tells it could be used in hydro grow)


My only other option is this US brand "HYPONeX" ( this brand is powder and could be used to mixed with water for hydro grow)

My last resort will be buying nutrients from a local hydroponic farm ( famers mixed all the elements themselve for commerical hydroponic grow)

I feel sososososo Bad having so less options.

Thanks again, for reading my long and troublesome problem..

I don't know how you are on money. If you don't have the money I understand. But can't you order some from online? You can shop for the best prices for free. Also some places give free shipping (if you buy X amout of $ for it). Just an Idea that will help you get a bet setup.

If you are using those nutes in the ebb and flow then they will be fine in the drip system rez just less concentrated for veg. And yes 3 times a day unles you se them droop, then maybe 4 times a day. or 2 times a day if it's too much.

The once every 7 days is soil instruction.

HI, Bigworm

Thanks for your reply.
I have never ordered nutrients from overseas.
Just the thought of shipping it from overseas makes me feel much more expensive (I've never order some online from overseas)
You said some places give free shipping for certain amount of products?
That sounds great, but...any advise on where to buy on line and which brand?

(I'm just so troubled by where to buy nutrients, I could buy some from my local hydro farms , but I believe hydro nutrients are better and more advanced from overseas eg US, UK... )

Any advise would be appreciated ! Thanks

Hi Loc NAR,

Thanks for the advise. Maybe I'll just try one seedling for now; it just takes time to experiment. I'm growing two trainwreck aged 68days and 38 days. I've got videos in my profile, not doing well.

Any advise or tips on growing trainwreck? Just wondering if you know something about trainwreck.

Thanks

I haven't tried trainweck yet it sounds good. They are all about the same to grow. Do a search on General Hydroponics 3 part nutrients. Grow, micro and Bloom. They are the best to start with of coarse all the hydro nutes were developed in Amsterdam and for one plant, OURS. So most will serve the purpose. I get most from discounthydro(dot)com or BGhydro(dot)com. Don't forget to get some Cal-Mag plus and some PH up and down to control the PH. It's critical.

Thanks LOC NAR,

I'll do just that and buy those products. As for now, I'm just going buy some already mixed concentrated nutrients from my local hydponic farms (they grow lettues and tomatos).
At the same time, I'm expanding the my limited knowledge as I'm browsing through internet.

I found out that most hydroponic systems place an air pump and an air stone inside their reservoir. At least, wick system, Drip system, and water culture system use them. I'm going to use a Drip system for my vegetative room, and ebb and flow for my flowering room.

The question is... Does an air pump with an air stone be placed in a Drip system's reservoir really necessary?

According to my reference, this function is to give oxgen to the roots, but does it prevent the reservoir from producing other unwanted bacteria or.... some greenish algae inside the reservoir?

Reference: Simply Hydroponics - Replace bulb

thanks ..

Thats right, it will help prevent stagnation of the nutrient solution (unwanted bacteria). Although, algae shouldn't be a problem if your reservior is light proof and absolutely no light gets in because algae needs light to grow, just light your plants. Even a very small amount of light leaking into the res can allow algae to form.

I use an ebb/flow garden with a 25 gallon reservoir. My first two flushes I had not installed an air stone yet. When I emptied the res, the water was colored stronger towards the bottom of the tank, and the surface was coated in a darker "sludge."

After adding the air stone, the solution stayed consistent in coloration with no build up on the walls. The plants seemed much happier! Cheap improvement with great results.

Thanks Loafyboy,

You've been a great help. Now I know adding an air pump and air stone is very necessary or without using an air pump and stone as long as I keep my reservoir light proof.

Thanks for patiently answering my questions.

In the kind of drip they show you will indeed need the air stone. I would go with the local nutes and see, they probably make a very good mix.

Do a search for LOC NAR. It's back a few years and funny. I did drip with constant drip 6 plants in a 10 gallon tub and no airstone. Now It's a must. The more air in the water the better.

Hi, what I meant was you should have an air pump/stone AND a light proof reservior. The air pump will prevent the build up of unwanted bacteria (stagnation of the water), and light proofing prevents algae. You need both an air pump and light proof res to keep the nutrient solution in good condition.

Loc NAR,

Thanks for the info. That's funny, the viedeo which I learned how to grow hydro never mentioned about using an air pump and stone. That's odd but I think it's must (I surely don't want to take risks wasting time and seeds) I'll stick to using air pumps and stones. You've been very nice and informative answering questions to such a first time grower like me.

By the way, have you ever tried the buds you grew yourself, do they have a chemical taste to it as some people say, or do they smoke just as good as other more organic, or pure soil grown buds?

Thanks...

If not flushed good at the end I can tell a some what strong taste and sometimes can give me a head aak. sorry for the spelling. Flushed out is much smoother and just as good if not better. Only when compaired can you tell for sure.

HI LOC NAR,

Thanks, I get what you're saying. It's just that, at what stage (5 weeks before harvest..pr 4 weeks before..etc?) do you stop feeding nutrients (Is this called flushing? or Does stop feeding nutrients mean flushing? )

Thanks for keep answering my unending questions. I hope my too many questions don't get people tripping while reading this stoned.

Thanks again.

2 weeks before harvest is when u stop nutrients, yes thats called flushing, u can feed them carboload, AKA molasses up to your harvest, its a simple sugar that will help your buds produce, but wont give you a chemmy taste when used without flushing

That's right.

I mostly go with 1 week of PH water at the end but went 2 just to see and it was really smooth. I loved it but some thought it was different so I told them instead of Hawaiian x skunk it was Pineapple Express. LOL. There are chemical flushes that only take a few days but I have never tried them.
