earliest flowering?

I was also wondering is it good to have some of the red spectrum in the veging stage.

Sorry about the delay. I have heard so much about growing it. Veg. for 1-3 mos., then flower another 1-3 mos., harvest while the trichomes are still clear for that clear high, and harvest after they become cloudy for that "muggy" high. Me? I'm just gonna try it all and see. If the short period clear trichomes work best... I did grow some a long time ago...went from 24hrs 1st week, 22 2nd, and dropped light accordinglywhile increasing the darkness. Used 2 shop lights with 4 bulbs each standing on the ends and white constuction paper (board) around the sides. No light from the top. Grew bushy. But whatever works ...works !

I have been wondering what the time span is for CFL plants from planting until harvest. I prefer the "Sativa - cerebral" instead of the "Indica - blah" feeling.
I have heard that if you harvest the buds at an earlier time (when they are smaller), you'll get more THC (Sativa type high), and less TCB (Indica type high). THC converts to TCB? (T/F ?) after the buds become larger. How large? Too many ?'s ?
Hey, I like to read the instructions before I use a parachute. Know what I mean?
S.S.

The amount of Indica or Sativa in a plant depends on the seed.

//A mix of red and cool is good for vegging.

Thanks Bongman, I was basically referring to the THC/TCB content and if early flower harvest affected that content. Can't remember where I read it but I will find it tomorrow.

I'm not familiar with anything called TBC. Maybe you are thinking of CBD(Cannabidiol). THC and CBD are the two most abundant cannabinoids in marijuana, but the actual effects of CBD are not fully determined. It interacts with the THC to change the properties of the high, whether it be to increase or decrease it.

CBD in large amounts is supposed to be a creeper, but lasts a long time. The high is described as a strong buzz or the body feels heavy and relaxed. You could associate this with the Indica high...perhaps Indica strains have a higher concentration of CBD. After all, CBD can make up as much as 95% of cannabinoid concentration.

when do u guys think i should flower my plant i was thinking about a week i should veg for then flower or could i flower earlier and have good results? i'm using 42 watt cfl's.

You should flower your plant when it's ready to flower. When's it ready to flower? When it's sexually mature enough to flower. When's it sexually mature enough to flower? Usually when the nodes start alternating, rather than growing opposite each other, usually after about 8 weeks vegetative growth grown from seed. Clones take on the age of their mother and can be flowered much earlier.

You can flower it before then, but you'll lose both potency and yield. An 8 week old plant has more cannibinoids than a 1 week old plant and the older the plant gets the more cannibinoids it develops.

Plants use both parts of the blue spectrum and the red spectrum for photosynthesis and the different wavelengths of light control different plant functions. For healthy vegetative growth, you need both blue and red parts of the spectrum. However, you don't need as much red spectrum as blue spectrum in vegging and how much more you might need depends entirely on the quantities being output by your current light.

You're right, the type of 'stone' you get depends largely on when the plant is harvested, and this is dependant on the colour of the 'glandular stalked trichomes' that develop on the calyx bracts, leaves and stems. An 'early' harvest, when the trichomes are still clear, will give you an up high, or 'head' high, a early-mid harvest, when the trichomes are 50/50 clear cloudy, will give you a bit of both - a head high and a body stone, a late-mid harvest when most of the trichomes are cloudy and some starting to turn amber will give you a 'body' stone or couchlock, and a late harvest when all the trichomes are cloudy with 20% or more turned amber will give you a 'heavy' couchlock almost narcotic stone.

You're a little bit confused about your THC's and TCB's (whatever that is )

Marijuana produces a number of chemicals, some of which get you high and some of which don't, which are collectively called Cannabinoids. The main three we're interested in are called ∆9 Tetrahydrocannabinol (THC) Cannabidiol (CBD) and Cannabinol (CBN).

THC is the primary chemical that gets you 'high' and is produced in the largest quantities in the 'glandular stalked trichomes' that cover the calyxs, leaves and stalks of the female plant. CBD, appears in various quantities in all Marijuana plants and when combined with THC tends to control the start, duration and finish of the 'high'. CBN, is produced from THC as it oxidises and decomposes and is primarily found in dried and cured bud as the THC content starts to break down. CBN is responsible for that 'couchlock' affect experienced with late harvested bud.

As can be seen from this, the later you harvest, the more the THC found in the 'trichomes' has decomposed and the 'heavier and more couchlock' the stone. The earlier you harvest, the less time the THC has had to decompose and the more 'up or head high' the stone is.

so what if i have more of the red then blue would that make things more difficult?

well would i be able to grow a succesful grow with just a week of veg because i don't have the money to keep it on for months? i was also wondering what the 5k stands for on the cool white tube i have and if its good enough for 1 plant?

That depends on what you mean by 'successful grow'. By vegging too early, your harvest and potency will both be diminished but you may still get something out of it. In my opinion, the minimum time you should wait before flowering is 4 weeks from seed.

Honestly, if you can't afford to veg or flower the plant for the correct timeframes, then perhaps you might want to rethink your growing.

The 5000k stands for the colour temperature in degrees kelvin of the light output. 5000k should be fine for vegetative growth, but not for flowering.

i also have 2 42 watt cfl's and a 2 daylight bulbs. the daylight bulbs give off 640 lumens each and the cfl's give off 2700 lumens each. should i be using the cfl's or daylight bulbs for veging?

What type of light are the daylight bulbs and what kelvin temperature?

As long as the CFL's are 5000k or above they should be fine for vegetative growth. Keep them about a foot above the plants for about the first week and then lower them until they're about 2 or 3 inches.

Lights that output a lot of light in the red/orange end of the spectrum tend also to output a fair amount of infra red light as heat which will raise temperatures and cause the plants to stretch for the light. This causes thin weak leggy plants instead of compact bushy ones, with tight internode spacing between the branches. The taller a plant gets the harder it is to pentrate the foliage with light in flowering.
