Hi, I hope someone can help. I had this White Rhino in a DWC system from seed on 18/6 with other seeds but they all died except this one, I think because the water temp was too high. So I transplanted this one into a Waterfarm last week and it hasn't grown hardly any. Its about 4 weeks old now...

hello all i have just got a waterfarm and i started using it today. the problem i am having is that this glugging/knocking noise comes from the res and the water stops coming out of the drip ring. this happens intermittently and the water stops dripping for a while. its annoying as its bloody...

my dwc res temp is 71.2f. are my plants going to die? i know it says it should be 68f but i cant get it down anymore, ive aready reduced it by blowing a fan on the water, this dropped it from 75f!

I just got this thing from general hydroponics called a cuttingboard. its just a rubbermaid with net pots and and airstone loop. but i dont understand how it works - should the water level be above the bottom of the net pots so the rockwool cube in the pot is in the water, or should the water...

i'm thinking about getting an aerofarm http://www.eurohydro.com/aerofarm.html, which is basically just a bucket with a pump and mister attachments to a tube. My question is - when the roots get long they will be IN the nutrient solution, doesn't this rot them? I'm a bit confused about this. I...

I have a whole load of Canna Terra Flores, Canna Terra Vega, and PK 13/14. These are designed for soil but would it be OK to use them in a drip system instead, surely they can't be that much different to hydro nutes are they? thanks!

So if you grow clones in rockwool in net pots with a few pebbles on top, in a bubble cloner, is it easy to take the clones out of the net pot to plant in pebbles for a drip system? or might you damage the roots when you pull them through the net pot? thanks!

I have a small height with which to keep my cuttings and am wondering what the best light to use would be? I don't think I'll be able to use t5 tubes as I read that you have to keep them quit far away? My current thinking is using a standard fluoro tube, does anyone know what wattage I should...

Hello For my next grow I would like to keep a mother and use cloning, but I have a few questions. How do you select the mother plant? I guess you have to pick a plant that is vegging and wait till it shows female preflowers? How big will the mother plant be? Is there a way to keep it small...

I'm very confused - my 2 Northern Lights look both male and female, so perhaps they're hermie? But what makes me think they might be female is that the pistils are growing out of the ball sack looking things, rather than growing seperately. so it seems as though the ball sack looking things are...

I'm thinking about trying out a hydro grow but would like some advice from you hydro growers on which system to choose. I am limited by space for now so really my only options are the aquafarm ( a bigger waterfarm), which I hope to be able to grow 4 small plants, or the aerofarm, which is...

Hello all I'm new here, glad to find this place with its own CFL area. I'm not interested in reading about HPS grows, these CFL grows are far more ingenious. I have just started my first grow with 1xblue 125w and 2xred 125w CFLs. I'm having doubts as to whether this is enough lumen output...
