How Much Yield To Expect

[Gary Busey]

^I agree, now that I notice the setup he's using. That SH setup isn't designed for an 8-week veg period, more like 3-6, depending on how many slots you fill, and how fast they grow. His idea doesn't sound too far off though, if he's only expecting 100 grams per harvest, times 2.

How many watt are your bulbs? You can expect about 1/2 gram per watt, per harvest, if your plants are healthy, and your lights are setup properly. If you wanna boost things, and are on a tight bidget, grab a bunch of 23/26 watt CFLs and throw them in there, the more the merrier, illuminating the areas closer to the edges, where the main lights won't penetrate.

The site that sells those SH systems has their own forum, and there are a lot of decent smaller grows/journals using those. I've seen 3-6 smaller plants go all the way from seed to harvest in those on that forum. But at the same time, being that is the site that sells them, I wouldn't be surprised if the results they claimed are not so accurate. Decent forum and decent product nevertheless.

And those smaller CFLs do work wonders, if you use enough of them. They're perfect for filling in light gaps.

shrinkage is a bitch

Especially after swimming.

Well, thanks again everyone for the feedback! I will try to optimize my lighting, and hopefully I will reach my first grow goal. And that is to succeed in making at least 100 grams out of all 5 plants. xD If I can do that, I am happy. I will improve from there in further grows.

 

[Gary Busey]

I do wish you the best of luck there.

You could use LED or HID lighting to increase yield in addition, or in place of those CFLs.

Blackstar LEDs are pretty decent for the price.... And there is a nice 150 watt HPS for $66 at HTG.

from seed stores i always see growing period is 7-10 weeks. does this mean from the day we start planting till the day we can smoke our own mj is 7-10 weeks later?
From above as stated should expect to pull around QP per plant...but on all seed stores i see its around 500grams per square feet or something...so thats about 17.5 z. so which is true?????

thanks!!

 

[Gary Busey]

The time they refer to is for flowering. That is just your 12/12 cycle. Not veg or seedling stages.

And it is X amount per square meter, which is 10.7634 square feet. And that is for a 1000 watt light per that square meter.

since theres someone good at replying here im just going to throw this at you.

ive gathered information for a week now and here is a list of equipments im going to be using....after you folk's suggestions. Please feel free to tell me whats good/wrong with these equipments, or even how to get cheaper versions. Im going to plant 4 plants aiming around 80cm tall as room is an issue for me.

1. Dimmable lumatek digital ballast 600W ($263)
2. Sunmaster 400W and 600W Dual spectrum grow lamp - 55,000 and 90,000 lumens respectively ($63)
3. Euro budget reflector ($30)
4. pair of easy-roll adjusters ($12)
5. maxiswitch 2-way light controller (10A) - day/night ($63)
6. RUCK100A - acoustic ducting - 230m3/hr - good for 600watts of light ($191)
7. budget 5 filter use for 125mm ($70)
8. bud box 75cm x 75cm x 100cm ($124)

Total of $814 but with discount and finding some other cheaper prices on ebay i believe i can get it down to around $650

Is this a good setup though? i dont have the chance to talk to anyone about it so i rely fully on this forum but people tend not to reply my threads....

Also do i need another fan for inlet/exhaust?

And is the 2 way light controller really necessary?

Also i gather with my light setting my plants may get sun dried??


What other equipments apart from nutrients and soil that i need?



SORRY about all the questions, just cant stand to wait anymore to ask one question one by one.

everything sounds fine on your list but this light timer will work http://cgi.ebay.com/POWER-STRIP-SURGE-GROW-LIGHT-TIMER-8-OUTLET-15-AMP-24-H-/120679784720?pt=LH_DefaultDomain_0&hash=item1c19136110 only $28 instead of your $63 one, also how big is your room? you might be better getting a coolshade for your 600, makes it easier to control temps if your limited on space. your 4 inch ruck fan seems to be expensive when you could get this http://cgi.ebay.com/6-Inch-Inline-Duct-Fan-Exhaust-Blower-vent-Hydro-NEW-/230639152700?pt=LH_DefaultDomain_0&hash=item35b32a2e3c

I need to hide from landlord so is not much of a room really. can only devode 60x60x160cm and a closet for hiding for plantation. I have selected the fan and light settings as above, but i am uncertain if its the correct equipment for my particular tent size and number of plantations (four).

 

[ROBSTERB]

the 600 hps is over kill really for a 2 foot by 2 foot room but if your going to use it you will probably need a cool shade to keep temps down, also you will need an osculation fan to blow the air around inside the room,

alright mate, i dont have to use the 600W lumatek ballast nor the euro reflector. i just read them on a web and their description seems good. out of all the lights the 600w ballast is the most expensive so i though the price reflects the quality.....obviously not now.


So what light and reflector should i be using in this 60x60x160cm tent?

 

[ROBSTERB]

well the 600 is the most efficient at puts out 90,000 lumes compared to the 400 at 50,000 so for the extra 200 watts your getting twice as much lumes, the 400 hps covers an area of 3ft x 3ft so would do that room nicely so you could buy the 600 dimmerble and dim it to 400 during veg then if you can control the heat turn it upto 600 in flower! you will def need the cool shade though some thing like this, http://www.rightpricehydroponics4u.co.uk/powerplant-aircooled-aerowing-reflector-no-cord-374-p.asp i use this hood and works great hardly any heat with a 6inch 450 cfm fan sucking through it.

Great man i was just looking at the same reflector. I was just speaking to a friend of mine that has been growing for several years now, and he said those 600W dimmable are shit!! i am now very confused cause i honestly though those are the best available for my price range. any suggestions???

 

[Nocturn3]

If you only have a 60x60cm area to work with, you should be looking at a 250 hps. You may be able to handle a 400, but you will need to go overkill on extraction, and draw your air from somewhere cool.

I'd go for a 250 if I were you.

With a 250 does this mean yield will fall since less lumens are reaching the surface of the plant?

 

[ROBSTERB]

probably yes i would go for the 400 as long as you've got a good fan sucking the air out you should be ok, like i said above 600 is overkill but will penetrate further down the plant producing bigger buds, the 400 is also much better than the 250, instead of digital just buy the magnetic ballast, a 400 is only about 70 pound and that's with the bulb

also have you not got abit leeway with the space? could you not make it 3 ft by 3ft?

www.bulkhydro.com has lumatek 600s for 174 bucks and free shipping. Hotilux HPS bulbs for 82 bucks.

 

[Nocturn3]

Yes, 250 would generally yield less than 400, all things being equal. However, a 400 will, in my opinion, cause you too many problems with heat, especially since it is your first grow. The ideal floor space for a 400 is 3' by 3' (90x90). A 250 is most suited to a 2' by 2' (60x60) area, and you will still get plenty of light for the plants, due to the fact that the bulb will be able to be kept closer.

A 250 should still yield well enough (250 grams is quite possible, but you should probably only expect half that amount, until you get things dialled in properly)

 

[ty816]

thanks for the info man. but i dont get it, how can it overkill? i though the more lumens or watts the better - given temperature is not a problem

 

[Nocturn3]

There is such a thing as too much light, at which point the leaves will start bleaching and not process light as effectively. Anything over around 10,000 lumens per square foot is overkill, according to what i have seen and read. 5000 lumens psf is a good minimum amount to aim for, and even a 250 will exceed that in a 2x2 area.

A 600 will definately be overkill in that area. A 400 is do-able, and will probably increase you yield over a 250 if done properly, but even then you will have teething problems, and will have to keep the bulb further away from the plants (reducing the light intensity available to them), or get an air cooled setup.

 

[jawbrodt]

^Not really, positioning is everything. I use a 600 to cover a tad more than 3' x 3', and with it placed about 18" from the tops, i get around 8,000 lumens per square foot. I use a light meter, which is the only way to really KNOW what kind of intensity is reaching your plants.
