| What about the seeds that are only suppose to grow plants about 2ft tall. I know someone that let them germinate for 5 days then put them in the rock wool about 7 days ago. They are just starting to have leaves. Should you let them grow to a certain height or a certain length of time before blooming them? |

You can flower your plants when ever you would like.
The longer the veg time, the bigger the plant will get in flower. |

| I'd say wait at least 2 weeks maybe more depending on how well they are growing and how fast. |

| It's been a week and they are just barely sprouting, one still has the seed hull on it. I read some where that you should just use pure water until the first leaves grow, is this right? The water is tap, but it goes through a filter system first. I'm going to have to have my friend change bulbs, it still works but I'm not sure how old it is, I thought it may speed up the growing. Maybe this is normal for this type of plants. |

I combined 3 if that's okay, because they are all applicable....

I assume your talking about AF's? (Autoflowers?)
AF's will essentially , under 24/0, anytime, anywhere, begin to flower....indoors, out, any light cycle....
Anything else can be vegged to any size and triggered to any size you like....

Veg time is dependent strictly by headroom and space available......you can flower them now (essentially 12/12 from seed.......) You can wait a week...you can wait 3.....
Whatever you like......but, make sure the person who has them has the space and headroom....
Note: Stretch is strain dependent...if heavy sativa, your looking at a significant stretch...if a heavy indica, you might be looking at minimal stretch and be sorry you didn't veg longer..so...something to be aware of.....if somewhere in between, results somewhere in between, so....(you also might want to give them a little veg time, then shave them a little (take a couple clones), and then trigger them.....
Note: Don't switch to flower nutes the same day you flip down....

And of course the reverse......and, applies to indoor or outdoor across the board as a rule of thumb (earlier in season, more veg time, larger they are....as one moves farther into the season, less veg time, the smaller they will be, etc......)

1. If unsure about bulb, should definitely change for new round....
2.First week or so is a little slow....after that, they will grow pretty fast.....
Feeding/water...your looking at till first set (coty's, first set, not first true set) yellow...as this is what they are utilizing......some start with extremely light feeding sooner, but, if a new grower, one should always be careful feeding....wait till they start to yellow and this is the sign...
Note: Feeding and needs will increase with size, so, expect an increase in diet as you proceed.....(Lot of new growers have deficiency issues early on due to this.......The larger it is, the more they eat...and more often..(but, depends on system/method also.......soil you'd be lighter dosage and less often than hydro, etc....
One reason for controlling size is even with 1k's......your penetration of canopy could be minimal.......ie: 1k and 6ft tall plant....1k and 3ft tall plant, etc........controlling veg and size is also controlling penetration of canopy....(6ft away from 1k is essentially useless......you'd still get something, but, would be better off trimming bottoms (use for clones) and focusing on upper plant/canopy, etc....
Light and genetics are your yield....and light is also density...(but heavy heat can also affect density, etc, so, always assuming all factors are in line.....)
Note: Issue with any SOG method (many plants, short veg) is your numbers determine your penalties...so.....something to be aware of and easily double checked at Norml site |

| The light is going 18/6, he should be letting it go 24/0? |

| There is about 8 ft for height |

1. 18/6-24/0....either is fine.....many do both....some say 18/6 will give better growth as "rest" period, but, some would readily state 24/0 extremely rapid rates (I would agree with the latter, and prefer it...)
2. Remember, your "headroom" isn't ceiling height, it's 2' more or less under reflector/bulb at max height!
If 8ft ceiling?....well, might be looking at, in the end, 4.5' max plant height, etc...distance from ceiling to bottom of reflector/bulb, then adequate distance between bottom of reflector bulb and tops of plants..(which is also determined by what lights....if cooled/vented hoods, or not....heat is the primary issue, not light....
Note if not a cooled hood.....heat rises... |

| How far should the bulb be from the plant? It's in a closet and he has a vent that comes on when the light does, it sucks the hot air into the attic, but the temperature at the base of the plant is still about 110 degrees. I read somewhere that the ideal temp is 70-80 degrees. Is this a big deal as long as the plants aren't showing signs burning? |

Vern in Joe's last post, its 2' more or less under the reflector/bulb. or always as close to tops as you can with out burning them.
peace & overgrow |

110 at the base would make me assume medium/rez is similar temps....which is an issue......
That's running way too hot man.....slower growth, possible root rot and such, etc.....
Regarding slower growth...if that is the temps at base, think of canopy temps....result going to be looser/not as dense product....
Gotta cool it down in there....work on all aspects (circulation, canopy, rez, medium, etc)....from the "sophisticated" (fan, cool hood,etc) to not.(ice cubes in rez, etc...) |

| There is a fan going to the attic running 24/7 but it isn't enough. I was looking at some of the self contained growers, some have built in AC's. They cost about $1,500. Do you think these are worth the investment or just wait until the temp drops in a couple of months? |

Well, as above, lot of people vary their activities with seasons in mind..(outdoors in summer, in during the winter) for exact those reasons...)
Some regions, even with a/c, difficult to control temps in the summer due to outside summer weather.....
Could look into changing hood.....(cooled/vented hood)....could add light in winter....
Attics always going to have temp issues due to the basics (heat rises, winter cold issues, etc)......such can be a problem in "dialing in" certain spaces with temp issues, etc...
Equipment usually a great investment....returns it 10 fold (see, people usually try to rationalize how much it breaks down to per batch..(ie: $1500, so, say 1/2 p more or less)....when really, the question is how much does it break down to over the 20 batches one will use it  (which might be a quarter z, etc...)
Not to mention might be talking increased productivity and yield....ie: the equipment might change yield in itself by cost.....)
Could also do a combination...ie: cool hood and also cool space which will heat up without a light up there to begin with, ya know?
Attic spaces notoriously hard to deal with in areas with extreme hot or cold.... |
