I always use 24/0 for vegatative growth and 12/12 for the flowering cycle. Cannabis in vegatative growth does not require a dark period to rest from photosynthesis. Think of your plant growing outside. Pretty much getting 12 hours of lights a day. Now imagine that plant getting eternal sunshine. With 24/0 you can get two outdoor days in one day indoors. This will cut down your growing time by 50% compared to outdoor growing or by one and a half if you just did the 18/6.
thanks for that info. at which week do you start your 12/12? also i have the light 24 inches away from plant with a fan blowing in between. exhaust vent in on and my humidity is about 35%. put a bowl of water in the room trying to increase the humidity.
-What strain are you growing so I can estimate when flowering will begin?
-Humidity is really low there. Might want to look into a humidifier.
its really up to you when to flower. (bigger plant, more bud!)
but anytime after 3 weeks of veg will be ok!
i got these seeds from jamacia last month the weed was super strong.
Depends how large you want the plants to be you can flower about 1 to 3 months after vegging.
took some pics, the plants were a little over 6ft tall.
As long as calax formation begins you can induce flowering.
new at this . what is calax formation?
small nodes appear between stem and branch.
sexing the plants, ok gottcha. iam keeping an eye out for the male plant.
iam having a problem with the heat and humidity. i brought a humidifier have that running its at 40% now, and the temp is at 90%. i have the exhust fan running and a fan between the hps and the plants. i have a fan blowing fresh air in underneath the door. grow room is 4x6 with a 1000w hps. any pointers?
the light is 2 ft off the top of plant.
I'm assuming your growroom is 6 feet tall by 4 feet wide? You will have to give me the depth of the room as well before I could calculate the Cubic Square Feet of that particular space. Until you get that information to me I can tell you this. You should have your exhaust blower mounted near the top of the room and have the intake at the bottom. Having air blow in under the door should be fine and is known as a (Passive Intake). Remember cool air stays near the floor and heat rises. The farther up you go the hotter it's going to get. If you could get me some good pics of the entire room and the door maybe I can design something up for you. How many cfm's is your exhaust fan rated for? Remember I need the exact measurment too. Height Width and depth. Have a good night.Quote:

From seed it is recomended that you veg for 6 weeks at least to get the full potential of the yield and overall health...clones don't matter cause they are geneticly identical to the mother which should have veged for more then 6 weeks anyway.
This is the truth guys,you can flower early but it wont be at it's full potential.
the grow room is 4x6x8, a spare bathroom i converted to a grow room.
more pics
switched back to the flo lights, temp is good, humidity is good, no serious problems from that little scare. how often should i be watering these plants?
temp pic
i will keep it like this for the next 5 weeks.
Your growroom is 192 Cubic Square Feet. You should be using an exhaust blower with a CFM rating of over 192. Heres a few images of some good exhaust blowers for sale. http://www.gchydro.com/detail.asp?product_id=XACTIVAIR If I were you I would at least be using a 265CFM model. It's reccomended that you reintroduce new air into the growroom at least once every five minutes. For optimal results you can reintroduce new air every one minute. With the 265CFM model you will be exganging old air for new air 1 and 3/4 times every minute. That will help reduce your heat problems if you install it correctly near the top of the room or door. That room you have there could be a really nice set up if you were serious about it. If you want me to design you a professional growrrom and you have cash to buy the equipment I will draw up plans for you. You could get quite a few plants in there and if you sold some of what you grew you would have your money back in no time flat. Anyways lemme know. Water when the container feels almost dry. ALMOST.
You can use the HPS light right now. A good way to tell if its too close is to place your hand right over the top of the plants. If your hand feels uncomfortable so will your plants. So just adjust the light. It's 100 times better than fluros. If you insist on the fluros keep them no more than 2 inches from the plants or they will stretch to all hell and back.
for me to install a 265cfm in my grow room i would have to cut a hole bigger than my vent hole i already have. also the ventwill push the heat and the smell out to my front yard. any other solutions?
Vent it up into the attic or over the roof possibly. Or a activated charcoal filter. You never told me if you wanted to set up the room professionally.Quote:

what kinda soil are you using and what kinda nutes are you going to use
using miracle-gro potting mix/ w miracle -gro continuous release plant food. feeds plants up to 3 months
I despise Miracle Gro. :D Check this out www.foxfarmfertilizer.comQuote:

i got some big bud and white widow coming real soon
I'm not growing at the moment. Just moved and have to set up again when I get spare money which isn't going to be anytime soon. But I did use Fox Farm Ocean Organic Potting Soil.Quote:

what about the cool light tube? 80.00
You could use a cool tube. Or you could get an air cooled 1000 watt system. Or you can get a 400 watt system. I have one of those for sale. Click the link below my signature. All three suggestions will work. With a cool tube or air cooled reflector you can get the light alot closer to the plants but you still need to buy an exhaust blower with it. Or buy a 400 watt and you can place it somewhat closer because it does'nt get so hot.
did a little bit of an adjustment with lighting during the veg stage. can you give me a little input on how this looks? added 4/23w soft white flo lights on sides. do the leaves look like they are dropping down. thought it was overwatering so i held off a day. last watering 3 days ago.
Mobay you told me in a earlier post you had to give the bathoom back eventually. Have you ever thought about building a grow box? The last one I used was 6 feet tall by 4 feet wide and 3 feet deep. I made it look like a pantry and painted it the same color as my wall. You should think about that one. That way you can do alot more than you can in that bathroom since you don't want to alter anything in there.

The side lights will help. They look a little overwatered but not alot. Just water them when the container feels almost dry. Is that foil your using? If it is make dure its "dull" side out so you don't create any hotspots that will burn your plants. I use mylar myself. Did I show you this before? www.weedfarmer.com/cannabis/
see i have alot of space where i can build one but my girl smokes cigs and isnt that a bad thing for the plants. if not we can start building one tommorrow. thats one place she doesnt go. iam going to have to do something real soon because, iam getting a new front door installer on the 9th, and my growroom is right there. so if it can be done , lets build. i dont have nothing but time on my hands.
