heya thanks for looking this is my 1st grow! would like to know how many hours of light i need to give my spouts!!! do i keep the light on for 18hrs - i am only using a 20watt light just to give them light! also - im using small rockwool cubes, when should i put them in bigger cubes? afew of my spouts have grew afew inches within acouple of days and how wet do i keep the rockwool cubes, as last time the dryied out n died ( not gud ) Thanks
I'm only familiar with Outdoor growing, and lighting conditions..But, from what I do know, I don't believe 20W lights are effective enough. Rockwool is good, and you should see about moving them to soil, rather than larger rockwool cubes. It's a decent growing medium, but not much on nutes. Mist the cubes until they're damp, then wait until they're almost dry, and repeat. When your plant's a good 6-8 Inchs, with some leaves, you'll want to transplant into something like a 3-5 gallon pot. If you want a higher yield, go for a 10 Gallon, or more if necessary. Like I said, 20W doesn't sound at all adiquet. For an outdoor grow (Like mine) 5 hours of direct sunlight is the minimum, 8 is perfect. I'm not sure exactly how the varience is between indoor, and out, so you might want to try the General Indoor Growing area of the forum. I hope I helped some, peace.
thanks lion, im only using the 20watts for the spouts, tomoz i will buy a fluorescent light and keep it on them for 10days, once they have grown about 8" i will transfer them into my grow room, will start them off with 250watts for a month then 600watts. about the soil, im not using soil, im using a bubbler system, this is why i wanted to know when to transfer them into bigger cubes, but i know when now!
