first time grow first time here need help please

Some seeds man. Did you make that or is it a pre built.
Looks like a DWC system. (maybe aero clone table) I would suggest some rock wool, clay pebbles. DWC neuts, 1 pink tube(or spectrum light) in the lights, time and TLC. If this is your first grow and youre starting with DWC good luck and power to you. It is hard to get it all right, I suggest being slow and neuting very little changing your water OFTEN unless ther eis a O2 and filter system involved.

The airbubbles thing is under co2, you need o2 in the water to prevent stagnate stuff and root rot from what i have experienced. the co2 during flower to aid in fluffy and big buds. I only use co2 in small quantities for very little time.
other than that man. Plant some seeds and get it rolling.

 

Roy, you have lots of options. It's all about light output, and the accepted standard measure for this is lumens.
CFL's generate less leat, but the least lumens per watt, about 50.
T-5 high output fluorescents generate more lumens per watt (about 90) and a little more heat.
LED's are promising but unless you go high end American made results are hit and miss. The good ones are expensive. The regular POS ones are about comparable to CFL's. Many LED's are deceptive in that they do not draw full rated power.
High intensity discharge (HID) will generate the most lumens per watt, about 125, but also generate the most heat. You need heavy duty centrifugal fan cooling and cool tube reflectors to use these in a grow box.
A 4X4 plant canopy needs a lot of light. A typical grow would use at least a 600 W HPS to cover that area and generate decent bud production. Two 400W's would be better. With the right ventilation, it could even handle 1000W.
If you're not trying to fill it up, you can get by with CFL's - get 100W total actual for the first plant, and add 50W more for each additional plant. Minimum.
T-5's - each 4' bulb is 55W. A four bulb 4 foot fixture is 1' wide & provides 220W, OK for a 1X4 grow area. I'd recommend two of these over a 2X4 canopy, and some side lighting.

We could go on all night... Do some reading in the lighting section here - Lighting - Grasscity.com Forums
Play with the options, check your pricing & budget, & go do it!!!

Hope this helps, Bestaluck to ya.

 

That box is pretty badass. im liking it

 

you could probably even make that box into a flowering a vegging box. the lights, if you go with cfl's just make sure they're 6500k for veg and 2700k for flower or a mixture of both and use it through your whole grow. what is it that you need help with? i'm new to. already on my first grow. but been doing so much homework. maybe i can help

 

Hey Roy, been away for a few days but finally getting back to you. In my first pass at answering your question last week, I didn't really zoom in on each pic, just glanced at the thumbnails. But after reading your follow up questions, it's a little more clear. Unfortunately the answers are not that straight forward.
That's a purpose-built box and its bulb type is going to be dependent upon the transformers and ballasts built into the unit. You will have to match the bulb(s) to the ballast / power supply, or bad things will happen. Like exploding glass spewing hot plasma all over you and the surroundings. NOT GOOD!!!!
The big socket with the white reflector above is the mogul socket for high intensity discharge (HID) lighting. You can try tracing the wiring from the HID socket & see if you can locate the ballast driving it - it should be a metal enclosed box with a 110V AC power input. The ballast should be about the size of a shoe box. Probably also has heat sinks / metal fins on it to help dissipate heat. I didn't see it from any of the exterior views in your pictures, so it's either built in or it may be missing completely.
If the ballast is a built-in, you're going to have to locate it and search the safety labels for the ballast type (high pressure sodium is most common; but metal halide is possible) and wattage output rating. You may also be able to do some research & see if you can locate an owners manual, or call the manufacturer.
If it's missing completely, you should be able to replace it with whatever type of HID light you decide to use. Just be sure to check the connector type for the socket to be sure it's compatible with whatever ballast you select. And pick the wattage and type for your grow area.
Now that I understand this is a combo veg - bloom box, the wattage / lumen recommendations may change. You'll need to tell us the inside dimensions (L X W X H) of the bloom chamber only, then recommendations can follow.

Hope this helps, or at least gets you started in the right direction. Will check back in a day or so to see if you have found any more info.
Bestaluck to ya.

 

Yeah, saw the 120V AC on the pic; but that's just the standard line voltage for any electrical circuit / outlet. You're going to be looking for the HID ballast output wattage specifications; and whether the ballast is for high pressure sodium (Probably / most likely) or metal halide (Possible). These two types of ballasts have different starter circuitry to start up the bulb.
The ballast takes the 120V AC current and provides a preset wattage for a particular size of bulb. Most are preset for one wattage - 250, 400, 600, etc., corresponding to the bulb's rating. Some are switchable between two settings, most frequently 400 or 600 watts.
Keep feeding us info, should be able to get it figured out for you.

 

I believe those are digital timers that are labeled? A decent digital timer will run any ballast up to 1000 watts. But I would not trust the labels to define what type of ballast you have.
Did you pick this up used? Can you contact the previous owner? The more I think about this, I'm beginning to believe you did not get a ballast with the box. Which means more to buy than just a bulb, but at least you can tailor it to your needs.

The grow chamber is 33" high? That's limited headroom as you'll have to keep the plants no closer than 10" away from the light, leaving 23" usable vertical space. Are there hydro containers underneath? Or can they be fitted? Thought I saw net pot holes....
So 43" wide by 25" deep - that's 7.5 sq. ft. of usable plant canopy. I would bet it calls for a 250W HPS ballast / bulb. A 400W might be workable but with that extra light intensity, resultant heat and limited headroom you would have to rig a cool tube and a high capacity centrifugal fan.

Keep the data coming

 

OK, all good info. But all I see on the inside electronics is a fluorescent ballast - the long slender black box by Sylvania, 120V. I still don't see a high pressure sodium ballast so I'd wait for the owner's manual for sure.
As to 400W HPS bulbs, my first recommendation would be the Phillips Son T Plus. The Hortilux Super HPSTM is also an excellent choice; or the Sunmaster Super HPS Deluxe. All three of these are rated to produce 55,000 lumens. Get the one for the best price, after you 100% confirm the HPS ballast wattage question.
So the bloom box is essentially 3' wide, 2' deep & almost 3' deep. That's 6 sq. ft. of plant canopy, 67 watts per sq. ft. to the plants, which is very good (actually higher than I run- I run my 400W over a 9 sq ft area). You could get by just fine with a 250W HPS over that 6 sq. ft. grow area and not have nearly as much heat build up. AND be able to let the plants get a little closer to the light without burning them. So worst case, after you get the manual, if we discover the ballast is missing, you have options to add a new one. 400W will grow more bud, but 250 will be way more manageable for heat
The link you posted answered my other question on what type of hydro system it is. The thin lines running to each net pot look like drip emitters. Not my first choice in hydro due to their propensity to clog, but it's what you got so make use of it. You can always convert it to an RDWC later. Be sure the reservoir container underneath is intact & the pumps all work. Easy enough to test for a trial run.
Filter - looks like you have one. The long perforated aluminum cylindrical tube attached to the black gooseneck on the rear is your filter. Take it apart & make sure it still has your activated charcoal inside. If not, refills are available online or from most hydro stores. You can test it by firing up the filter and smoking a bowl. Exhale inside the box & run around to the rear, you should not be able to smell it. I can smoke inside my grow room & 5 minutes later you cant smell a thing!!!

Keep the info coming, we're getting there
