If you haven't already I would suggest checking this site for every Nft question you have. I have researched it a lot on this site and you should be able to find it fairly easy too..

this prolly isnt good, but i by flush do you mean change the water? LOL because i have 2 plants in seperate hydro setups and i havent changed the water in either one since day 1!!! plants seem to be doing great though..and i dont have any nutrients to add to the water..cant find it anywhere (the hydro thing was just for shits n giggles since im way new to all of this growing)

well, if you are giving them nutrients and you want to change from veg nutes to flower nutes, its a good idea to flush first.
flush would mean to use just clean ph'd water, with no nutes.

go to your local hydroponics store, they will have the nutes you need.
i would probably advise something that comes premixed. like gh floranova.

Flush means to empty the res and wash the extra salts out of the bucket before adding your nutrients into a new clean res. I flush my system once every 2-3 weeks and my plants love it. If the salts build up too much you may end up with root rot and will kill your plants. Salt buildup is from the TDS(total dissolved solubles) you have in your water. Nutrients add to the TDS of the water in your res. Washing once every so often (or flushing) helps to prevent problems like root rot and nutrient lockout. Hope this helps.

Hi,
I was wondering is there possible to plant seeds in clay pebbles just after germination? (In wilma system) And if it is possible how to do that? Once i saw a pic of this, but I'm not sure if there wasn't any rockwool under pebbles. :D Sorry for stupid question. :D I'm new to hydro. :)
 

wow!

hey all, way new to this but just one question right now,,, how the hell do you know when the rockwool cube has enough water? can I weigh it on a scale or someothing

any advice welcome much respect

I suggest not weigh them or other shit. Just keep an eye on your plants ant they let you know. By the way how old your plants are?
like two weeks, i've been readin here for a minute couple sick grows in here one foll growing bonzai trees and shit

I do all the time. Check out the link in my thread entitled "How to Germinate Seeds" You just let them go a few days longer then stick them root down in a net cup with hydroton surrounding it for support. Be very gentle with laying the pellets as they can snap the plant easy...

If germinating or rooting in the rockwool cubes they should weight between 25-30 grams on a scale. You can weigh them but it isn't necessary unless you want to assure 100% control over your grow.

You should weigh if using to germ or root... Should be more specific bud :D

I got a hydroponic system from a friend who used to grow vegetable. But the cups he passed me are only the size of a shot glass which I am not sure will that be enough for a mature plant... I will be sticking to mostly shorter strains, so what would be a good size for cups for them? Thanks in advance for any answers!

My systems run 2 and 3 inch net pots and it works great for them. Both sizes are sufficient to take a plant through to harvest.

Other people can't usually answer questions like that because it's personal preference. I personally haven't tried any of those so can't answer that personally :D

hello,

I built a couple of hydro systems and I used these knitting sheets rolled in cones for net cups (net cups weren't available to me when I made the system) I was wondering if the roots are goin to be consricted by the 1/8 inch holes in my net cones. Picutre below.

Yea and no. If you cut off the bottom it will work great as the plants get smaller roots towards the top of the root system but below they have what's called a tap root and tend to grow pretty big lol My biggest mother has a tap root that's an inch around. That may or may now stretch enough for them to grow through properly. Try a hole in the bottom of it and it should work out ok.
