How long to vegg in order to yield 2.5 plus lbs with 2x1000 watt hps & 10 Plants

Hi all,

I am just wondering how tall I should let my plants vegg to before flowering in order to yield 2.5 plus lbs at harvest? Hopefully more than 3 if its all dialed in.

There will be 10 plants under 2x1000 watt hps in an 8ftx8ftx8ft flowering room.

Currently vegging 3 G13 Labs NLxSkunk feminized, 2 Greenhouse seeds Himalayan Gold Fem, 3 Barney's Farm Blue Cheese Fem. Also one Candy Gram clone that is already about 15-18 inches tall (may also take some clones to throw in there too) but should only use around 10 of the healthiest plants.

Thanks for all your help :joint:

They don't necessarily have to be tall. Your lights aren't gonna penetrate very deep on a 6 foot tall plant. Check out 'mygirls' grows, he gets quite a lot for shorter plants.

2.5lbs with 10 plants,well thats 40 ounces,so you have to get a 1/4lbs. per plant,6-9 weeks of vegging guesstimated.Some LST is probably your best bet to get light to penetrate to lower branches and topping them at the right time to get multiple main colas.This will also increases yield

Do you think i would be better off doing a larger number of plants like 16? and vegging for a shorter period of time? Thanks for all the replies

get em' 24 inches(2 feet) tall, then clear off the bottom third of the plants..so the light is directed only at the canopy!!!fuck i just noticed you're growing different strains..oh well try to keep an even canopy by bending,topping, tying ect.good luck!!!

you shouldnt have to do much to or veg out your plants long to get 2.5 lbs with 2000ws of light.. maybe 3-4 weeks of vegging as long as you get good growth... with 2000ws of light, 2lbs would come out to a half gram per watt.. 2.5 pounds is just a little over that... that shouldnt be hard to reach at all.. but as was said if you cant grow then it doesnt mater how much light you have...

Thanks simpson..

how many plants do you think ill need to have in order to obtain this goal or even exceed it and hope for maybe 3 lbs.

Thanks everyone for all of your replies

You dont mention if you are using dirt or some kind of hydro setup. Or what kind of nutes. These will make a big difference in how much weight you get.

I think you are good to go. Using pots that size with decent nutes and soil, AND plenty of light, I see no reason you couldnt meet youir goal.

well if your goal is 2 to 2.5 pounds, which is 40 ounces, it depends on the bud structure you want... you could easily grow 5 plants the yield a half pound each.... these would have large heavy buds... or you could grow 40 shorter plants, such as autoflowers, and pull an ounce per plant... also take into consideration grow space... if you would choose to grow 5 large plants they are going to need more space to grow... you DONT HAVE to prune them, BUT will get much better results if you supercrop or top them.... personally i havent tried supercropping or topping much.. im sort of a let it go as is... mainly because i wasnt ever able to know how strong the seeds i was using were and didnt want to risk males and hermies due to stress.. i am getting some seed bank seeds and will be starting to supercrop though... anyways.. back to the subject at hand... you can fit a lot more smaller plants in the same space if you want smaller buds... not at all saying popcorn.. just not as big.... basically its like this... you have PLENTY of lighting whatever way you choose to go.. you ultimately have to decide what you want in the end and decide from there...

IMHO, with you having 2 - 1000w HPS lights that can easily penetrate about 3 plus feet worth of canopy, and i were you, and heat wasnt an issue, and space was plenty... i would do this....

5-10 large plants depending on the size of the room... veg them out for 4 to 6 weeks... somewhere to around 18" to 24"... then i would flower... i would do what i can to keep an even canopy... assuming they double in size you will have about a 4ft canopy... anything over say 4 ft would be lightly and very gentely tied down... a 4ft canopy will pretty much mean your entire plant will yield... this is also assuming the light will be WELL vented and can hang closer to the canopy without burning the plants...

there is a lot more to take into consideration... if you want an accurate answer where im not assuming stuff and can give you my real suggestion i need to know a few things..

1) is heat going to be an issue?? can you afford to properly vent your area?? with that much lighting heat WILL be an issue and can have adverse affects if you cant exhaust it properly... if you cant maximize your lights potential by keeping it closer to the plants because of heat then its gonna affect your plants and yield...

2) what size space is your grow space??

3) what kind of bud structure are you looking for?? ie 40 - 1 ounce buds or 10 - 1/4 lb buds... just as example...

with those questions answered itll be a lot easier to help you out and be more accurate and thorough in my answer... just at this point there is still to many factors to consider...

veg for 2 months in 7 gallon containers. Then flower. In veg transplant from a 1 gallon then to the 7 gallon. Either top at the 2nd node or wait until like the 6-8th and lst 90 degrees down so either way the 2nd nodes and all others become colas. I have at least 6 colas on my plants doing this. Lst and keep them short all the way. Keep the temps perfect. :)

1.Each light will be air cooled and sealed off. We will be using atleast a 360 cfm fan to suck hot air off the buld and out of the room.

2. The room is 8ftx8ftx8ft walk in closet

3. The fewer the plants the better, but we would only like to vegg for 4-6 weeks from seed. So far we were thinking 16 plants, 8 under each light and vegg for a 4-6 weeks from seed. how does that sound?

Honestly, that isn't much light for such a big room. And I hope you don't mean a single small fan for both lights. Single fans work fine, but 1k's produce a lot of heat and that is a pretty small fan to try and sweep it all away. I use a 450 cfm for a single 600. Granted it's a much smaller room, but still. Not saying your idea won't work, but your gonna have a build up of heat to get rid of somehow.

Have you looked into sog? If your going for strictly quantity than I would take a look at it. Especially if you've never grown a plant before. It's easy to say your gonna grow a certain amount of a crop, or have a goal of a certain amount, but actually getting there takes some practice, some knowledge and some skill.

2.5 lbs is a lot of weed, and if it were as easy as sticking some lights over some pots, then this would be childs play. Lots of things factor in and a lot of variables come into play. take a look around at some guys that grow big quantities and see what works for them. There is no one single and only way to grow, different methods work, and nobody can tell you that a certain method is the way to go. Because if you don't know what your doing with watering schedules, fertilizers, ph balance, strains, humidity, air temp, or air exchange then it's pointless. Experiment for yourself.

I will have 3 seperate fans for the room. 1 exhaust fan with carbon filter exhausting around 650 cfm, 1 intake fan pushing cool air into the room from the room next door at around 280 cfm, then one inline fan sucking hot air off the bulbs at around 400 cfm. I'm pretty sure that will be able to keep my temps under control.

and since my lights will be in cool tubes, I will be able to keep them a lot closer to the plants in order to promote more growth and be able to further penetrate the canopy of the plants.

Plus you insist that 2000 watts is not very much for an 8x8 room, however, from the research i have done states that a 1000 watt lamp can cover up to a 5x5 area, so two of those should be more than enough. Plus if you take into account that i will only be using a 3x3 foot print for each light, and each footprint will contain 8 plants, i'm almost positive that my light for flowering will be more than sufficient for this.

I guess I need to just figure all this out through trail and error and see what works best for me
