ok so youre saying mix this;

with;
http://www.amazon.com/ONA-Liquid-Co...1?ie=UTF8&s=home-garden&qid=1269944204&sr=8-1

then what? are you saying just to mix it then let it set out? or do you want me to actually plant my plant in there

that would be interesting! plant wouldn't last too long in ona gel
idea is to pump out air from your grow chamber into a bucket with ona in it
search the forums for ona bucket, gives some easy plans for building one

this is getting too complicated lol cant i just let it set out cause its in a cupboard with a fan circulating the air so wont that work?

that's growing, it gets more involved the further you go
try putting it in a bowl and have fan blow air across and out of your grow area, that's a very straight forward setup
it will help some, not sure how much, good starting point, if you need better, take it up a notch

Hi everybody.

Thanks for your kind words.

The plants, as you can see from the pictures below, are reacting just fine.

The dome is made from expanded polystyrene cutted with a computer aided machine. If you go back one or two pages you will see more details.

The box is quite stiff even now without the lower end. After is finished it will be a computer desk so i will be able to roll it around, there is still a lot of work/parts/money to go inside.

Exterior dimensions: 30''w x 32''h x 47"l
Interior dimensions: 23''w x 29''h x 35''l (usable space)

Any questions are more then welcome as I anyway bore my girlfriend to dead.

Yeah i suppose that would be tall enough for some shorty plants. Those plants now look very strong. Are you planning on running all the lights in that thing? (Yeah my wife is not interested at all with my build, im like "honey come check out these plants" shes like "they dont look any differnt than a week ago. leave me alone!!" so she quits looking at them...LOL.)

Update..

I've changed the pots on 3 of my plants.

It is looking like 4 of them but I've run out of soil and changed only 3. Little Frankenstein (middle of 7th pic) went back in his half-bottle.

in the first pic i see only 6 tubes... you were using 9x2=18 tubes? I see that they were only on top and one side ..or you remove some of them to make the pics?

the difference between t12 and t5 is more than consumption..

Look at my plants.. they have the same number of nodes but only 4 inches... you figure this out.

I was running 4 in the back, 4 on the door, 6 up top, and then added 2 to each side.

They will vegy just fine. It is when it comes time to bud is when you will need more powerful lights to produce a bountiful flowering.

KlosetKing · Apr 9, 2010

My lights. From what iam told its all about making sure you dont exceed your sq/ft light ratio. with these i only plan on 2, maybe 3 plants tops and from what i gathered online it is more than possible to get a large, dense yield, you just need to make sure you dont outgrow your light.

A guy buy the handle Bezzin is in the middle of a T5HO grow, and to be honest it is looking QUITE promising, and he is going t5ho from start to finish...

moobyghost · Apr 9, 2010

Pupu, great set up. It would be awesome if your timer could turn one light on at a time. That way you could have light that goes around in an arc like a sunrise sunset effect. When the lights come on it starts with one. Two min go by, the one above that comes on, repeat until all the lights are on and it is like the sun rising. It would feel more natural to the plants....that or i am totally baked. lol.

Either way, amazing setup.

In my experience i've found that the t5/t8/t12, whichever, are very good for vertically mounting in a flowering chamber, but not as a primary light. As it has been mentioned, keep them to the clones and let some real lights handle your flowering needs. If you can't afford the HPS/MH lamps, then I would sudgest using 2+ of the big boy CFLs, per plant. (I belive they are a 65w bulb with 200w Eqiv.)

Boston's Best · Apr 10, 2010

The quality of the cannabis is directly related to the quality of the fluorescent. T5's put off the most lumens per watt, so for the electricity you draw you get the most yeild. T5's are a great full term lighting source for flowering. Use the 6400/6500k (depending on bulb manufacturer) for veg and then switch out to 50/50 6400k veg and 3000k bloom bulbs for flowering. T5 still put of quite a bit of heat and are not air coolable, so plan on using an intake and exhaust fan to keep temps in control. Still, there heat output is nothing compared to HID lights. The only downside to T5 compared to HID is light penetration. The T5's don't throw light as deep as the HID's. If you keep your plants under 30" you should be fine. If you want to go taller, just throw some more T5 strips down below for coverage on the bottom buds.

If you consider T8's T12" and Compact Fluorescents, then the quality and yeild starts to come into question. CFL's really arn't cost effective enough. By the time you go to home depot and get all the cords and bulbs, at $6 a piece for the bulbs and $10 for the cord, to get the wattage you want to get the yeild you want, you should have bought a $150 4' T5 light. T8 and T12 can start seedlings, house mother plants, but not adequate for veg or bloom. Anyways if you ran 100w for T8 and 100W of T5, the yeild difference between the 2 would be substantial, with the same power usage.

I just did it because I couldn't use my HID at the time and it was good quality but very little in terms of quantity.

This set up has 8 t-8's on the sides
& a 150watt hps on top
It started with the t-8's because they are cheap and available.
Then I realized how cheap the hps was ($80) and added it

almost exactly what i have planned for my end setup, just going one step at a time

Hi evereybody. Long time no see.

My box is working just fine.. now are lited 15 tubes: 13 of 21Watts /1900 lumen/HE; and 2 of 39Watts/3100 lumen/HO

As you can see from pics everything is looking great ..to bad that only one female was in a big pot.. 3 males went to hemp heaven ..and 2 other females are in really small pots (last picture.

Today is exactly one month flowering, one week 14/10 and three weeks 13/11.
All the buds are hard ..no popcorn bud.

Big plant is now about 16 inches.

one more thing... ABOUT COSTS: My setup was quite expensive.. I've could had two 400 watter setups with the money invested.

I've wanted to explore the fluorescent side of growing ..push the envelope a bit.

PLS tell me your opinion on how is this plant looking for a 4 week flowering plant.

growone · May 12, 2010

looks primo to me,at least the larger plant buds look good
cost is a negative, but as you say, it's more of a proof of concept
looks like there is plenty of spare space at the moment
