Need your experience

Ηello everybody ! I am new to this forum. Could anyone tell how could i use my 250w lamp hps/mh in order to achieve max results from it? my goal is to achieve 200g of dried product? is that possible from a lamp like this or i need more watt? if u have any suggested seed that would work optimally under this lamp i would like to hear it! or any other advice for setup that could help me achieve my goal! sorry for my bad english.thank u in advance

Probably not going to make 200g dry with a 250w. You are more likely to get 200g from a 400w. Maybe if you run hydro like DWC you can get some crazy results, but probably not if it's your first time growing. Don't count your buds before they grow. You will be disappointed probably.
Last season I had one outdoor plant, and it only gave me 100g dry. I babied it and fed and talked to it and gave it the best of everything, topped it. Sometimes the plant just gives what it can. You will get better in time.

ok so for my 250w lamp how many plants under this one? any suggestions ? i don't have the money to buy another lamp-ballast etc right now so i ll try with this one this time? i also don't have the time to grow a photoperiod plant i ll try with autos, so about 2 autos will be ok do u think ? thnx bro i am happy i found people who love cannabis and can talk with them.

I say try it out with two and see how it goes. I don't know much about autos, but so long as they have room to grow and good light, you should be good. You might want to follow some growers who do autos regularly. Off the top of my head, I know that "justugh" is a really knowledgeable grower who likes the autos.

What do you mean "you dont have time"?
Autos are shit and a lot of them take just as long as real strains.
I have auto critical hanging right now that took 10 weeks of flower to finish.
I could have had a 8 week C99 that would have blown away an auto.

i want to finish my grow in max 70-80 days so thats why i thought autos would be best for that time. i have little experience with plants, i have acquired my knowledge as far as concerned cannabis grow through forums the past 2 years. so forgive me if i say something wrong. for example i thought how would perform 2 think different plants under this 250w lamp(i know that t.d has a longer flower period ) thats why i asked this question. auto critical from which seed company? flower for 10 weeks or from seed to harvest?

Auto Critical from Female Seeds. 10 weeks after the first hairs started showing.
Most autos will finish a week or two before photoperiod, but then I ask, why give up that much quality for just 2 weeks?
A batch is going to take 90 days from seed to finish, 10 extra days for more yield of much better bud isnt very long.
In fact I cant see why any sane person would diminish their product to save 10 days.
