haha, that's hilarious bro!! Hope those work out for you!!lol customer rating on this bulb
"I purchased this bulb to grow vegetables indoors and it works great. It's been on an outlet timer with an eighteen on six off cycle for about two months and it's still going strong. The bulb gets hot to the touch but not hot enough to burn the plants at five inches away. The plants are flourishing and the bulb is obviously a key factor."
yeah vegtables.....mmmmmhmmmmm. i should tell the dude that 2700k is not for Veggatative growth LOL
my area is only 11x14 Inches 4 bulbs will be alot in such a small space.I would recommend a larger number of smaller bulbs than fewer larger bulbs. You get much stronger more even light dispersal and can run more wattage for the same price.
Say you purchased 3 of these 36" 6 bulb fixtures for $13 each (look around you can probably find the same fixture for $6) http://shop.ferguson.com/product/Craftmade-CRM13036-Chrome-263264?N=102+214+3000650&cid=ga_falllt11_bathroomvanitylights&gclid=CLvY3eaNwawCFQNShwodbztWrg
Look for 23-26w CFLs at the dollar store or on sale - you should be able to find them for $0.25-1 a piece. For $60 you would get 400+w of CFL and it would be nice and evenly spaced over a 3x3' area (perfect for a scrog). You would also be able to stagger different spectrum bulbs to maintain the ideal 3:1 ratio.
Also keep in mind CFL efficiency; CFLs are most efficient lumen/w at 45w. The further you get away from 45w the less efficient the bulbs are - 23w and 68w bulbs are about the same as each other and just a bit less efficient than the 45 an 48w bulbs, the huge bulbs and tiny tiny bulbs are much much less efficient.
In short you will be providing alot more light to the plants by using separate smaller bulbs placed closer to all the parts of the plant then just a couple larger bulbs close to parts of the plant but far from other parts of the plant (keep in mind anything over 4" from a CFL is pretty far).
i was going to try for around 12 tops. 4 tops just seems like its not trying to push the limits of my space enough and thats the main idea.If you mounted those bathroom vanity lights to a sheet of plywood they would take up just as much vertical space as the two larger bulbs.
You would be better off with 4 45w bulbs than 2 105w bulbs. If you can only put two bulbs then get the highest wattage you can - it's less efficient light but it's still more of it.
11x14 inches? Oh... In a space that small and with the longer straight high wattage CLFs I would really recommend hanging them vertically and growing lollipops with the bulbs hanging parallel to the colas. It is going to be really really hard to get a good scrog in such tight conditions. Maybe just top once and then trim for 4 main tops - anything over 4 tops is going to be way overcrowded.
nah your fineLet me know if you want me to get rid of all of these pictures.
12 seems like a lot to me but Id much rather you say "told ya so"i was going to try for around 12 tops. 4 tops just seems like its not trying to push the limits of my space enough and thats the main idea.
but your more than welcome to say "Told ya so" when i dont succeed
thanks for the support . i really want to fill up that SCROG screen as much as possible for maximum yeild. I guess we will never find out what the limitations of the setup are unless we "Push it to the limit"12 seems like a lot to me but Id much rather you say "told ya so"
I'm rooting for you.
i have a small PC fan in the top of the box (there are a couple pics of it earlier in the thread.) right now i have it blowing air into the box to push air across the seedlings to help them strengthen their stalks. i can easily turn it around to suck heat out of the box .2x 250w CFL will cost more than a 400w HPS system so im not going to be considering that option anyways. i did look at the 105w CFL and they are in my price range. still a bit pricy but do able. right now the temps in my box are a little less than desired. probally 68-70f so a little more warmth would be good. i thought about placing a heating pad in there but didnt really follow through with it. they are growing fairly well with the current temps so i dont think they are bothered by the non tropical enviorment.What is your ventilation situation? Generally more light the better but I can't imagine say 2 250w CFLs in there - the heat would just be ridiculous and although the amout of light at the top would be super high I don't think it would be able to get to much of the plant matter and changes are you would just be wasting electricity. I would say go with x2 105w like you were thinking - even then you might have heat issues.
