Hey guys, my tap water comes out as 0.05 ec which is about 25ppm. Should I be adding cal mag to it to make up for this? The reason why I ask is that I've been experiencing very slow growth atm and after reading another post on the forum, I'm beginning to wonder if it's my water not my setup as...

Did you plants do anything else out of the ordinary other than not grow? curling downwards leaves for example?

well as long as the bubbles are breaking on the bottom of the netcups then it's not going to be overwatering. Are the leaves drooping at all? Thus it may well be the weak light intensity. how far away are the cfls?

26ks are fine for the first week or so but after that you're gonna want stronger lighting. The water is 3-4inches from the bottom of the netpots and they are still dripping wet? Are you using a real dwc or a bubbleponics system? If it is overwatering then adjust the level of the water in dwc...

well all the conditions are optimum so it's probs something wrong with the system itself, like overwatering. What is the water level in the dwc? remember you want the bubbles breaking just below the netpots, so the mist is wicked up by the hydroton onto the rockwool

haha thanks mostlycrazy =P - the first post of this thread is too good for it to just fade away - sticky potential imo!

bump - no one else agree?!

tmsculli this is a wicked post man you should reup the original pictures and add some more if you have any. not only does it display the advantages of bubbleponics over dwc but also provides a good reference for other users as to how well developed their plants should be at a given age. get on...

mate every single hydroponic store in the world sells netcups!

Hey guys, i've heard so many good things about super plant tonic n really want to try it. However, i've googled extensively and can't find any uk shops, or even any shops that ship to the uk that stock it. Have any other uk growers found it anywhere? Thanks all!

wicked man thanks a lot =)

Thanks for that informative post petrol420 - aye I thought letting the rockwool dry out a bit was a good idea too, but other more experienced growers than me recommended to just leave the pump on, but with the manifold adjusted to allow only a trickle. If they dont recover and continue to grow...

well they have always been growing, albeit very slowly - i can't see any difference between from when the water was at full blast compared to now when it is a trickle, the leaves are still droopy. but it has only been a day and i expect it'll take them a little longer to bounce back. fingers...

perfect mate, just what i needed, thanks a lot!

looking good jonny man, yours are already bigger than mine! think i managed to stunt mine by overwatering cause i had the pump feeding the plants at too high a pressure =( - hopefully mine will bounce back and catch up! what's that wee thing black thing just behind the plant? cheers!

thanks mate - can anyone describe what the water coming out the bottom of their netpots look like - i've set mine to a very small trickle that is just about a continuous stream - does that sound right? Cheers =)

sound mate, will do! Out of interest, when you look at the water coming out the bottom your the netcups, is it a continuous stream, or does it drip, but really fast? Thanks again!

Wicked thanks a lot guys - it turns out i can adjust the valves on my manifold to reduce water flow - so I have done that and it is much more of a trickle now, rather than blasting out like it was before. So hopefully this will solve the problem One last question though, should I turn off the...

Yeah I followed your tutorial to a tee roseman, it's amazing thanks a lot With regards to nutes, i thought I was meant to wait till three sets of leaves? I will be using floranova btw, not SH nutes

Yeah I was comparing my growth with yours roseman and yours is considerably more advanced =( - I am not feeding them anything, they are just recieving plain tap water. Dysotopia, unfortunately I can't adjust my manifold, though I actually might try connecting all four of the netcups to one...
