Ok, this is my first hydroponic grow and Ive done tons of research and of course welcome any tips, criticism and the like.

My flower room is not done yet, Ive got a 400w hps and a 4" centrifugal fan / carbon filter and that side is gonna be an ebb and flo system. Ive got some time to build that tho so im not worried.

On my vegetative side Ive got two four foot two bulb fluorescent with a cool white and a warm white in each one. The system is a rock wool recirculating drip system.

What i have growing so far, and they seem to be doing quite well, is the two on the right are my white widows, the 4 on the left are bag seed of haze. not sure of exact kind, but i know i like it.

The bigger ones are the ones i had started first, i think my nutes were a bit too strong the first go and i was a little worried about them, so i quickly started a new batch of seed just in case, and those are the smaller ones. So if the solution was a bit strong, they seem to have bounced back once i changed the solution. And the ones you see in the dome, those are 4 white widows that just popped. (If you look close see how they are yellow tinged? im thinking maybe too much nitrogen? hopefully they will be ok.) took a little bit longer than the haze.

and now im just maintaining them, they've been going for about a week now.

Looking good. whats your current drip cycle? how many times a day. approx how many drops per sec?

That is the one thing that i could not find a satisfactory answer for. Right now im on 18 hours of light. on at 5am off at 11 pm. I have a 160 gph water pump that waters 3 times a day, 6 am, 2pm and 10 pm. figured id just split it up evenly cause i cant find a straight answer on that. And thats the other thing i wasnt sure of...i found these drip spikes, you just plug in the 1/4" line and it drips down the sides of the spike, which then hit a little bar half way down the spike that kinda disperses the water. so, its kind of a constant flow, but not hard, very light, and it seems to just serve the purpose of saturating the rockwool for 15 minutes, 3 times a day.

If theres any other other tips and suggestion out there please post thanks

Looks good, though I'm not too sure that this is your first rodeo...

heh. Good luck.

LOL i swear to you this is my first time. i took a horticulture class YEARS ago, and besides a basic garden ive had no other experience. especially with hydroponics, but the concept seems extremely simple, ive done studying and research up the ass, and now im putting it into affect. see how it goes thanks

yeh 3 times a day is what i've currently got mine set to. u can check some of my other post. Thinking i might have to add another 15 min cycle in there as some of my roots have hit the bottom of my tub

for the most part. A few minor details that ive got plenty of time to take care of.

The flowering room is finished, aside from throwing up some mylar and putting the last piece of plastic sheeting to seal off the area completely. The ebb and flow system that will be in the flowering room is not complete yet either, but ive got all the parts i need already. One thing i am worried about is the table ive got in the flowering room might be too big. I wont want to put that hps up too close to the ceiling, but i got a 170 cfm in line fan and carbon filter venting out, should be plenty of air flow for the 4 x 3 area.

Also, the babies are doing amazingly well so far. I was a little worried about them all at one point, thought i gave it too much nutes in the beginning to start out, but it looks like i changed it early enough.

Keeping the ph down is definitly proving to be a bitch, every day it seems i have to add some ph down.

I just upped the nutes today to mild growth....keep my fingers crossed there

great stuff mate. just came to look for some updated pics

what ppm are ya on now? my grow is on 4 waters per day now

hopfully bumping nutes up some more. its currently EC 1.0 (700ppm)

what u using to get ph down?

I dont have a ppm meter just yet, for the simple reason that i just haven't been able to afford one. So, ive just been going by General Hydroponics nutrition schedule for a 16 gallon tank and i change the reservor every 12 days and its got an air stone in there. I figure that should be just fine, and it definitly looks like it is, cause they are growing so fast and good, im amazed really. And i test the ph everyday and i use GH ph down. The problem with that is there no good directions on how much to use, so i just kinda squirt like 7 ml in there if its lookin like its going up. I keep it around 5.8, but it fluctuates almost daily so....i dont know, im not too worried about it.

7ml of the ph down? hopefully u get a ppm/EC meter soon. ebay have em fairly cheap and its WORTH it.

u may find sometimes with too much ph down it increases PPM/EC (salt) levels.

I went to the hydro store and got some ph down ultra concerntrated for about $3.50.

few drops (prolly less than a mil) and it drops ph down quite a bit. Bad ph down was causing me major headaches in the beginning.

i must admit i splurged on my EC metre went and got a proper bluelab nutrientr truchneon bout $120 but ive seen some on the ebay for around $40-$50

i was finding that even if i followed my instructions down to a T, EX/PPM was still off lol.

EC wand solved it all lol

but hey as long as your babies are happy and healthy your doing it right
