The plants were transplanted about 3 days ago from soil to hydro.

I would really like to know how much my estimated yield will be if i do not switch to HPS lights and just change the flouresent to 12/12 when plants are ready to flower and use them to flower.


any advice/tips would be great!
Thanks




Using
  • 15 gallon container
  • 2 2ft flourestent lights on 18/6 timer
  • Peters 20-20-20 nutes mixed about 7 tbls to 15 gallons
  • 8' air stone with fish tank pump
  • fan for oxygen
  • hydrotone

they look bad, peters 20-20-20 in a hydro setup? get some nutes made for hydro. whats your ph at? might yeild a quarter of bud dry. those lights need to be alot closer too.

OK the problem is that we dont know anything about our lights. we just bought to 2ft fluoros from wallmart and hung them up. Well funds are limited. Ph is about 6.8. i just moved the lights up to take a picture but there closer than that. So you think we will yield 4ozs as is? we obviously havent sexed them yet.

not even close to 4oz, 1/8 of an ounce dry maybe.

the light came w/o any packaging and dont have anything written on the bulb and ballast? Look in the lighting faq section and learn what it is that you need in a light and what all the various things that you should look for mean.

op-Pretty much nothing, even if you veg a long time that will just result in a bunch of fluffy as hell stretched buds that dont have enough light. Dialing in your setup perfectly helps, but lighting is very very very important. tubes only penetrate about 2-3 inches in, so if you want a decent yeild from them you would need to get alot of side lighting. Alot. lol. You should also get a few red spectrum tubes for them.

other guy Not really, you can make it through the seedling stage but thats not gonna be enough for good veg growth imo.

If you're growing with floro tubes you need to surround the plants with them as they only penetrate 4"-6" effectively. Add some CFLs.

Check out the grow in my signature for examples about growing with floros.
