yes, lumen counts are expressed in number of lumens

no, lumen counts are expressed in number of lumens

no, the surface area of the canopy in squared feet is what matters, not volume in cubic feet or the height of the plants... fluorescent lights should be kept within 1-3 inches of the plant tops cuz lumen intensity dramatically decreases about 6 inches from the bulb

yes, and more is better

i dunno i don't use 100W bulbs or shop online

would 5.5k lumens per sq foot suffice for a small dwarf plant such as LowRyder2?

Like, my container is fairly small, to small to have a ballast with an HPS, and 7k lumens per sq foot is a lot of lights for this small container.

sticky_bud

Aim for like 4000-5000 Lumens per square foot. 7,000+ lumens is like best case scenario with proper ventilation...

2.65sq/ft with 4000 lumens per square feet is 10600 lumens
I.E. (1) 26w cfl = 1600 lumens
(8) 26w cfls(208w total) =12800 lumens which is 4800 lumens per sq/ft

I use a 70w HPS and a 65w CFL for a total of approx 11,000 lumens in 2 sq/ft works very well with autoflower dwarf MJ check the link in my sig for more details....

that's the ideal cannabis plants thoroughly enjoy direct and blinding hot summer sunshine

but i think my plants yield decently with less than the minimum recommended 2000 lumens per square foot until i can offer more anyways

Ok, that's good. I was planning on doing something like.... plugging 2 4 way light sockets into my 2 lamps. Allowing for 8 lights in 2 lamps.

Only problem is I don't know what they called.

I called lowes and asked the guy if they had them, and after explaining it's like a Y socket but with 4 instead of 2, he got me and said they did have them. By the time I hung up I realized I forgot what they are called.


What are they called? a Y socket adapter but with 4 spots for lights instead of 2.


8 lights, 24 watts each = 192 watts, which at about 65 lumens per wat is 12480. For my container that's just at about 4-5k lumens per sqr foot. So if I can only figure out what those 4 way adapters are called I will have my lights covered.

Dr.Budz

Dude, just put as many cfls in as space/temp allows.

xtensity

Ya but I need to know what those adapters are called that you screw into 1 socket, and it lets you screw in 4 more lights.

Looks something like this ...

sticky_bud

those 8 lights will produce a comparable amount of heat to the setup i've described with a 70w hps and a 65wcfl....

i dunno if theres a lowes near you but they have 70w HPS for $34.99

HPS will penetrate a lot deeper than cfls.
In my box the plants under the HPS side do get heavier more dense buds.
I am considering switching to a 100w MH or another 70w HPS in that box instead of 65w CFL...

Does HPS not require a ballast? How am I going to hang that in a container with a lid, meaning lid from the top of the container.

sticky_bud

the ballast on 50w and 70w are little computer boards that are like size of a 3x5 card with capacitors on em and such....maybe an inch and a half tall.
the ballast are easy to remove from the housing as well as the bulb and socket...
I am an electricity novice and have done this with no help.
