got some questions, need some answers!!

setup

-400 w hps
-150 w hps which i move all around the room

10x 13x room
grown in soil

nutes i have been useing... sensi bloom part a and b, organic bat guano as fertz, and some normal 15-30-15 plant food(blooming) and RO water

8 plants flowering at 4 weeks old
6 plants were just put in

soo 14 plants total under that wattage.

they are all growing very well the 4 week olds are already getting to that frosty stage and getting there way to turning into nugs not just hairs

my questions are.....

1. how much yeild(dry) would you think i get out of that 8? please just geuss dont give me the bs. juusst GEUSS yall.
2. i have heard to gain a nice ending yeild and a bit more frostiness that you put your plants in a dark room for 3-7 days with no light then chop it down?
3. whats your way of flushing soil?

btw the strains that are 4 weeks old right now are ice, ak48, and nypd

so you only vegged them for four weeks before flipping the lights i take it? how big are your containers? i would guess anywhere from around two or three zips per plant should put you in the ball park, maybe a lil more, hopefully no less than that..
i've also read all about the dark period at the end of grows but don't have any concrete evidence either for or against it...
as for flushing in soil.. i don't.. i think its a crook of sh#t that has been passed on from one ignorant grower to the next, again with no concrete proof of it doing anything other than starving your plants in the last two or so weeks of flowering..

the strains sound potent. the yield all depends on the light you give them and how you treat them... I'm going to guess that you will get about 5grams to a Pound. I think I'm in the ball-park

thanks guys, and ya im using 3 gallon container like i said with a 400 and 150 watt hps. and what was this thing about starving ur plants?

18plants in three gallon pots is alot of foliage for such little light; therefor, i would guess maybe half LB since the bud might be fluffy. But, on the other hand, if you keep your lights close together the plants canopy near the buds should bulk up. Now. That me being honest! Again, with all respect but I run 10K for flowering. I would upgrade to a 600HPS or two You have the room to run 4k no problem! Even better, run a 30amp 12gauge line thats 240v and you have all the juice for your room. And get a box made for your 4 time 2 continuous (120V) box for your ballast. Doing it this way would keep you smoking for six months! or help pay for school, mortgage etc But you would not sell your hard work would ya! lol
