ok.. the last guy is way wrong.
The SUN gives 10,000 lumens per sq foot, 50,000 lumens per square foot would be retarted and unproductivly wastefull. To even get 50,000 , it would take 3, 1,000 watters in your 3x3 area to get 50,000 lumens per sq foot.
A 600 watter is best for efficiency and it will provide almost 10,000 lumens per sq foot to your tent at 85,000 lumens per bulb divided by 9 sq feet.
If your looking to get a good yield fast, id recomend doing a hydro scrog with rumple bubble buckets. Easy to DIY and make for a reasonable price. Thats just my oppinion and what I personally did myself.
He also has a DIY cloner that is crazy useful, but you would need a reverse osmosis water filter. If you have that, its just add water and let sit. no special anything. and a claimed 100% success rate
Scrog method will increase yield , tho it would be ideal to be able to get to 3 sides of your tent from the outside, otherwise you'll have to cut like 1/2 of a foot off the front part of the screen to be able to reach.
Here is a pic of results of one plant that rumple did his his Bubble bucket scrog. He uses co2 so without co2 it wouldn't be quite this good, but still. It's what inspired me.
Below here is a post I made to someone else in the beginner forum trying to convince him that the bubble buckets were the way to go in my opinion. I was going to link the links for those here, so i figured to save myself time i'll just quote that post.. Pardon the hugeness of it, Tho it does have some information in it. Gardenmaster a high rep guy on the site liked the post so it must not be that far off.
First let me start by saying, I know where your coming from. Had I had the funds ready when i started planning a grow. That exact Kit on that Exact website would be in my house right now. (it was a cheapo hydro kit not worth time that he had linked)
Let me elaborate as to why I am infinitely grateful I did not go further with it.
Not that it would do poorly, but you have the chance to start right, and in my honest opinion that kit is not the one. Firstly it can be built for cheaper, Secondly, there are better ways. The only thing in my newer plan that I considered keeping was the 6 way water manifold. That was only because I was too lazy to try and figure out another way to split water into tubes with one pump.
Now I know you said you would prefer to have it be one large container. The issue with this is, Roots on different plants don't want to live together. They get all tangled , and all share a relatively smaller root zone area. The larger your root zone per plant space the larger your plants can get. That kit you linked holds 6 gallons of water for 6 plants (or 3-4). Lets go with 4. 6 gallons nutrient solution divided by 4 is 1.5 gallons per plant. As where the link I'm going to link is a very successful bucket design from a highly reputable source on here, and his buckets give One plant 3.5 gallons. More roots = more plant, faster growth.
In his design, It's one plant per bucket. However all of the buckets link together in one system, and the beautiful thing is. One bucket doesn't have a plant, so you can use a water pump to empty your system if you want. The extra bucket helps PH buffer the system, and gives you one to work with. Also with a bigger bucket with 6" pots hydroton rocks and plant shade the opening enough you don't need to bother with covering the holes. (light is bad for roots). On top of all of this. One bucket has a Fill indicator tube so you know how much is in the system at all times without opening the lid; also fill and drain spots where you don't have to open the lid either. This opened up the opportunity to do a scrog where before a hydro scrog seemed unmanageable.
The main advantage over and beyond what I've already mentioned is that If one plant has 3.5 gallons of oxygenated nutrient solution to sit in and fill with roots. Your plant can show a much greater potential than if you had 6 plants sharing one small container. In the size tent you use. If you (and i advise you do) look into the SCROG method, With this bucket design you could fill that tent with 3 buckets, 2 plants. You want to make sure you get an MH bulb (hopefully your ballast is digital and can take MH bulbs) for Veg.
As for oxygenation that was mentioned. Its extremely important. The more oxygen you have the faster the plants will grow, and the more it will help prevent any root zone issues, some of which can ruin crops. So don't skimp on the air pump, get a good one. I'm getting a dual diaphragm air pump from general hydro, may be a little overkill but I want too much oxygen if anything. You could just buy a smaller GH pump for each bucket. The "work" bucket that doesn't have a plant , doesn't need a pump. Tho i will be putting one there anyways.
All in all, If you make the bucket I'm going to link , its everything that kit you linked is and much more. The only addition you will have to have is in one of the buckets with oxygenated water you will have to have a water pump , splitter, and tubing to get two streams of water going to your rock-wool cubes like demonstrated by that Kit
(IF YOU HAVE TO START FROM SEED, if you can start from clone (grow a mother in soil in a closet or something or buy clones) then you dont need that at all you can just raise the water level an extra inch so that the bubbles splash water on the hydroton, and the hydroton will wick it to your roots for the few days until the roots hit water, then you lower back down to 3.5 gallons[varies based on net pot size, this is for 6" net pots).
Unlike with that kid you don't need all six manifold exits, you'll only need the two. and you don't need it in that cheapo mock up they did. You'll get better yield off of 2 plants in separate buckets than 6 in that one. Or even 6 in a 10+ gallon one. This route may end up costing a few extra dollars in the end. But with the comparison on how much you will spend on electricity over time compared to the potential improvements this set up would give over that kit , the cost differential at start up is minuscule at best. Now bare in mind this is all opinion , but seeing the results people get off these buckets , I, Myself would grow no other way, even tho ive seen many, many other ways that work. PS if you find pictures somewhere in the thread I'm going to link that Rumple himself posted of his fully grown garden, Know he also uses a 400 watt hps, normal 2x4 closet. Tho he uses co2 and his grow is controlled by an environmental controller to keep the temp and humidity right.
Either way go check it out. I'm going to use my own air stone set up, he has a DIY one that isn't really needed imo. I'll also link his clone bucket, cus I feel its valuable information. Also the Aluminum tape idea is great. You want absolute zero , in the amount of light in the res column. Light makes roots grow root rot, and that's disastrous. Also keeping root temps at 60-65f Is ideal, above 70 can cause root rot. The cooler the water is, the better it holds oxygen. and on another note. I know I briefly mentioned this before, but I personally wouldn't be caught dead doing anything except a Scrog regardless of the rest, based on Your height situation alone.
Feel free to re post and let me know what you think, or if you have more questions. :smoking:
P.S. I agree with the other poster that said It would be better to grow one strain. Go pineapple express, thats what im currently growing, and I did so because it is also my first grow. =D I bet it will smell like god's vagina.
Feel free to post follow up questions if you like
