Rockwool no Hydroponics?

[pobamela]

This is a stupid and noob question..
Can I grow weed in rockwool but not in a Hydroponic system, I mean, not with an auto pump but guving water like is in the soil?

rockwool is just the medium you start your seedling in,you can use it in hydro,soil or even get a rockwool slab for it to grow on...yes you can use rockwool and water it yourself

Technically if you're not using soil, it is hydroponics. Not all hydroponics systems use pumps. Passive hydroponics, like what you're describing, doesn't require any of that.

In a word, yes, you can grow exactly as you describe. Just make sure you're using proper hydroponic nutrients even though it doesn't seem like a hydroponic system. Hydroponics is simply soil-less growing, so you'll need exceptional solubility in your nutrients just like you would in a more stereotypical hydroponic system.

I recommend Advanced Nutrients. There just isn't anything better.

I agree you can grow in rockwool with excellent results. Keep in mind you should adjust your PH when using Rockwool. Ive done just what your considering, I grew it just like hydro using hydroponic nutes and adjusting the PH. I basically works just as well as any other hydro setup. Currently I prefer to usie soil or bubbleponics.
Good luck

This is not true. Not all soil-less growing is called hydroponics. You may have heard of aeroponics and bubbleponics. Neither of these are hydroponics, and neither use soil. I would also not recommend growing in rockwool unless it is used in hydroponics. You can use it if you want, but it will dry out really fast, normally its used in applications that are watered frequently such as ebb and flow and drip emitter. If you are just starting seedlings in it, you can set the cubes in a tray with about a half inch of water in the tray. The cubes will wick up the water, kind of a ghetto hydroponic system if you will.

all of those are hydroponics..hydroponics just allows you to relax because it waters itself..main thing is hydroponics is growing without soil

This is not true there is no problem with using it in soil. It drys out as the soil dry's out then you just water again

He's talking about soiless. And the set it straight, cubes in soil dont dry out at the same rate.

Dang knowboddy was right. I looked it up and any soil-less growing is referred to as hydroponics. I am a man and I can admit when I'm wrong. I think its kind of stupid, bubbleponics, aeroponics, and normal ebb and flow or drip emitter systems are all so fundamentally different. Aeroponics are highly oxiginated and the roots grow basically in mid air, bubbleponics the roots never leave the water, and we all know how the other two work. Just doesn't make sense to me that they are all lumped into their own category. I think they should use different criteria to label something hydroponic other than just "not soil", but I don't make the rules, so oh well. I was indeed speaking of soil-less rockwool when I said it would dry out fast by the way, I think thats what the original question was. Anyway peace, sorry for my contribution to the spread of mis-information, won't happen again.

I handwatered mother plants in Hugo blocks no problem. It's as easy as it is effective.

 

[earlymorninstonepeomp]

Go for it. Once I found out what a pain in the ass pumps and feeder tubes were I pulled it all and did just what you're asking about. the stuff will dry up if you don't watch it but if you give her a good feeding every day you'll be fine.

BOTH Aeroponics and bubbleponics use a rez full of water. The only difference is the way the water is used. its ALL HYDROPONICS. the only difference is an airstone, or a bubbler. Hydro = Water = HYDROponics.

I already apologized and corrected myself further down the first page, I'm only doing it once. Plus those variations in the way the water is used is pretty f-ing significant don't you think?

How much faster does rockwool dry out than the soil?? im starting some germed seeds out in wool cubes, n then im just gonna transfer teh cubes into some soil once the seeds become sprouted seedlings. I know i only need to worry about it until the roots outgrow the cubes, but how often do you need to water a wool cube as opposed to soil? every day as opposed to every 2-3 days??

 

[TheDankness]

This is going to sound stupid, but soil uses water too, just delivered by hand. So why isn't soil hydroponics? The only difference is the growing media, and I don't get why soil is all by itself and rockwool, coco coif, and all that other hydro stuff is all referred to as hydro, just because its not soil.

Yeah every day or maybe a couple times should do ya. Or you could try setting them in shallow water and it will wick the water up itself.

Once you put the rockwool cubes into the soil you no longer have to worry about the rockwool.

"I recommend Advanced Nutrients. There just isn't anything better.

I recommend any good plant food specific to your stage, veg/flower, that DOESN"T cost 40-50 bucks a pop for the small bottle. I've looked into it extensively and the difference between Advanced Nutes and something like a Shultz product are NADA. I've grown the same strain, side by side. one with Advanced Nutes 3 Part Sloution:Mother Tea as well as Sensi Grow and Bloom, and the other with Miracle Grow. YEAH I SAID IT. The difference at 8 weeks was zero. Not a bigger yield, not a better aroma and damn sure wasn't any better weed. Give your babies a good plant food, keep your ph in line and its all good. The biggest difference in yield and quality in my experience has to do with medium. The more air the more frequent the feeding the better. Rockwool is excellent, So unless your taken by the stoner friendly product names or the pretty picture of the BIG BUD on the label don't go throwin away all that cash when it isn't necessary.

 

[TheDankness]

are these hydro nutes you guys are talking about organic? if they are then I have to say that this guy must be crazy. I used shultz all purpose for a while and my plants started showing Mg deficiency, and the growth was slow. When I switched to the Pure Blend Pro, I noticed a difference over night. So I'm going to stay with the good stuff thanks. I mean, for all you know the plant you were feeding with MG would have been twice the size if you would have fed it organically.

 

[pobamela]

Tnx for your answers.. And how much and how often I must feed with the water?
I have the General Hydroponic Trio Nutes. Are them good?
I bought for my soil automatic plant but seems it don't need it..
It's for the next year by the way...
