And im using 2 400 w MH for these stages , isn it enough ?

Are you using, 2 x 400 w lights for 170 seedling/plants? If that is the case then that is definitely not enough light for all those plants.
the more plants you have, then the more lights/watts and room that you need.
170 plants is a lot and you will need a lot of powerful lights to grow them good(your current lights will not be good enough).
If I were you, I would scale down the number of plants you are growing to a reasonable number of plants( about 6-12 plants IMO) and then use reasonable lighting.
If you do want to grow a large number of plants, then you will need to get more lights/watts than you have right now.

i think the stem is very skinny and tall ,
dont u think is a little bit late for fixing it, its about 2 weeks from germinating

Marijuana will grow pretty much under any condition. So even after being far from the light during early vegging state, the lighting can be fixed and the plants will grow much better.
But because of the mistakes you made, the plants will not reach their full potential, and will turn out weaker and have less buds then if you did not make the mistakes.

The decision to continue growing or starting over is up to you. In my opinion the direction you are headed with your current grow project is NOT good, and I think you can do a lot better if you educate yourself on marijuana and start over. I would advise for you to start over since you are only 2 weeks into the project. You do not want to waste your time continuing growing for months, and only get a very small harvest at the end. If you do start over, and have good basic knowledge of growing marijuana, then you can grow some high quality marijuana.

If you do start over, then you should do A LOT of research, so that you know all the basics of growing MJ. After you have done your research, you should estimate how many plants you want to grow, and then you will need to estimate how many lights/watts you need to grow them. It seems like you did not do much research in your current grow, and because of your lack of knowledge on growing MJ, you have made a few critical mistakes. Growing marijuana is not as easy as it looks, and it requires a lot of your time and attention. Not just putting a bunch of seeds in pots and putting it under a couple of lights.

I would also suggest you create a grow log with all the details and information for your grow set-up in BASIC GROWING. If you do create a grow log, then you can have a well documented grow project, so that people can advice you on how to grow your plants better. you can also get advice for your day-to-day problems that occur, so that the problems get solved right away, rather then wait until it is too late(like your case seems to be). If you do not want to create a grow log, then at least look at other grow logs and learn from those logs.

I am no expert in growing though, I am just giving you basic information that might help steer you in the right direction. You will get a lot more interest, attention, and help from experienced/expert growers on BASIC GROWING section then you will here in the INTRODUCE YOURSELF section of the forums. People on these forums are always willing to help out, but you will need to do a lot of your own research first before asking for a lot of help and answers for questions.

Peace be upon you:hippy:

I'd like to help out here.

I was just surprised that you started with soooo many plants. You are going to spend so much time pruning them.

Anyway, my opinion is a little different. I would NOT say start over again, but take a little different approach.

First, there is no way to successfully grow 170 plants with a total of 800 Watts. I have a 250W setup and I have problems getting enough light on 3 plants...I like them to get as much light as possible. I am sure the light is good for up to 6 plants, but it won't cover the entire plant.

Option 1. Install more lights. My opinion, get (at least) 3 x 1000W MH and 3 x 1000W HPS and set them up all at the same time so you have 6000W shining all the time. MH will help vegetative and HPS will make them grow faster. This is a technique used by greenhouses.

How to save on power cost? You use the professional marijuana growers light schedule instead of the standard 18/6 (18 hrs on 6 hrs off) or 24/0 (lights on all the time).

Use this schedule instead - 12 hrs on - 5.5 hrs off - 1 hr on - 5.5 hrs off.

The average yield per watt (how much weed you will produce) is approximately .5 grams per watt, so more lights, the more results you will get.

Second option - Poor mans approach.

I hate killing plants just because. Especially these ones...

If you want to keep the same lights as you have without buying more powerful ones, then move 150 plants into another room and just leave the light on for 24 hrs. I did that once, so I am speaking from experience. I left a few plants on my desk and by the window because I didn't have a grow box yet and I grew them for about 4 months under a 50w light (the 50w light was the regular room light, not a lamp with CFL shining on the plant. The light was the one on the ceiling. It was so weak that the plant didn't even bother stretching 8-))..it grew SLOW. That's ok, because when you take them back into your grow room, they grow like crazy because the root systems are much more mature. You could almost SEE them grow, it's that fast.

OR (spend a little extra money)


What I suggest is to buy 2 x 1k Watt HPS lights and make another room. When the first 20 plants are ready for flowering, you put them into the HPS room, then move 20 more plants into the MH room and when the second set of plants are ready for flower, move them to the HPS room and keep doing that. I think by the time your third set of plants are ready for flowering, the first set of plants should be finished flowering.

Sooo...

Move 150 plants into another room with a regular light and near windows, so the sun can get in. Start with 20 plants under your 2 x 400W MH lights. When they are ready for flowering, move them into the flowering room with 2 x 1k Watt HPS lights (12/12) (there is an advanced way to do this as well, but it won't work with this setup because of the moving of plants). I can explain this later for a stable grow.

Move second set of 20 plants into MH room...grow until they are ready for flowering, then move them into the HPS room...by this time, your first flowering set of plants should be around 4-8 weeks into flowering. Depending on your plants, flowering should be done by weeks 8-14. You will have to research on how to see if they are ready to take down.

Keep on doing this till you are finished all your plants..THEN..dont do 170 again unless you have enough light.


I hope you are in the middle of nowhere or have real good carbon filters because they will STINK! 8-)

nice advice Steveat.

I advised him to start over because, even if he puts the light closer, he will still have the problem of not having enough watts to cover all those 170 plants. It seems like he overlooked a lot of things and just winged the whole growing project. I personally think it is best if he just starts all over, rather then waste his time with weak plants that haven't had any proper lighting for multiple weeks. If he starts over with 10-20 plants, and adds a couple more powerful lights, then he will be much better off then trying to continue the mess that he started.

But that is just my personal opinion on the whole subject. I definitely like the alternative that you have given him though, that way he could still use all the plants that he has already grown.

it seems like he has some major problems that he has to fix regardless of whether he starts over or continues.

1) light is not close enough to plants - this is easy to fix, just put the lights that you have much closer to the plants, but not to the point it damages the plants.

2) too many plants - I would suggest to scale down significantly(10-20 plants), but if you want to keep all those plants, then you will need a LOT more lights and powerful ones.

3) not enough lights and watts - whether you keep 170 plants or scale down, the current lights that you have do not produce enough watts to grow marijuana optimally. so you have to get better and more powerful lights, or just a lot more lights with more watts.
