Not my first grow but first grow log!

• Indoor grow cab (converted Home depot wardrobe)
• 4 pots, two left over KC-36 and two Dutch Passion Oasis
• Makeshift growlight - featuring a 125 watt CFL (rated 5000k) with an aluminum turkey pan reflector
• one bottom fan (and digital thermometer) blowing cool bottom air at the pots
• One top fan 'sucking' the warm air up
• average cab temperature 27 Celsius
• After 3 days of sprouting only one seedling (one of the KC 36's) popped out of the soil (I did presoak the seeds for 12 hours) on Aug 5th
• Still no action with the other seedlings, so I'm soaking 3 more Oasis seeds. This time I'll monitor every 12 hours and only plant them once the seeds have split open.
• I'll add a 45 watt soft white CFL to the current one when flowering for extra red spectrum.

Here's what it looks like so far:

I like the light setup haha pretty ghetto :D
good luck to you mate! keep us updated!

u get much bud with that amount of CFL light?

Good luck man! I sprouted under a 12" fluorescent above my sink when i was just messing around, can't wait to see how it goes!

Yeah what kind of yield was your last grow?!?! Don't let them give you shit about it either keep trucking rubber ducky!

CONVOY!

err...... sorry flashbacks of old movies.

"featuring a 125 watt CFL (rated 5000k) with an aluminum turkey pan reflector"

I love this m8.
This one I'm gonna follow. I love when people just look on ther situation and see what they can do and jump right into it.
I am sure you will get bud, hang in there and don't expect loads of it. Do keep us posted though man there are far to few grows like this here even though I am sure they represent a very large portion of the growrooms around the world.

Best of luck.

Yield...I really have nothing to compare it to, I guess it's passable for a small grow of a few plants at a time? I've been changing things at every grow too, keeping what works and improving on what needs to be improved.

The big 125 watt CFL and the Home Depot wardrobe I got last year. I've been adding various CFL's and light fixtures over the past two years. Heck my first Mango grow was in a much smaller cabinet, using a pair of 45 watt soft white CFL's.

As long as the cabinet temps stay within a safe range I could use the 125 watter with both 45 watters for a good light spectrum with enough reds...that would give me 215 watts for a surface a bit smaller that 2 feet square.

The current setup is discreet enough not to raise attention and the wardrobe doubles as an actual storage compartment when I ain't growin'! ;)

Based on Roughrider's info:

2000 lumens sq. ft./21500 lumens sq. m. = Absolute minimum for growth. You won't get much from this, especially after the plant has grown a bit. Not really enough to flower well.

3000 lumens sq. ft./32250 lumens sq. m. = Pretty Good growth. Enough light for the entire light cycle, although your yields may be lower.
4000 lumens sq. ft./43000 lumens sq. m. = Very good growth. Once you pass around 3500, growth rate and ability goes up fast.

Over 5000 lumens sq. ft./53750 lumens sq. m. = Optimal growth. Dense growth in all stages.

I measured my wardrobe's floor and it's well under 2 square feet. The 125 watt CFL generates approximately 13895 lumens, which would fall into the "pretty good growth but limited yield" area.

I went through my CFL box and came across a 45 watt rated at 3000 lumens, 4100K. So I figured that by supplementing the 125 watter with the 45 watter I'll be in the very good to Optimal growth area...

The three Oasis seeds I was soaking have begun to sprout, so I planted them. Here's the setup as of this morning. It was a bit of a challenge to get everythig to fit, but I've come up with a good compromise I think...the 45 watter is focused on the KC Brains that already sprouted out, and the three Oasis are crammed under the 125 watter...current cabinet temerature with both lights on: 29.3 Celsius, within safe parameters...keeping my fingers crossed! :D

That's one powerful CFL. I noticed most 125 watt's are rated for between 12,000 - 12,800 Lumens after googling it. But still that's alot.

I just might have to go get myself one.

It was an approximation based on a chart I found (should have saved it) stating that a CFL with a 5000K temperature can generate 111 pupil lumens per watt, so I multiplied it by 125 which gave 13875 lumens (someone 'splain to me the difference between lumens & pupil lumens?).

I calculated that for optimal growth my cab requires 15500 lumens. As you state, 12000 sounds more like it, so if I add up both CFL's, 12000 + 3000 I get 15000, so I'm still pretty close to optimal, if it's more like 12,800 then I'm actually exceeding optimal!

Temps settling near 31 Celsius...still acceptable but I'll really have to keep an eye on it an make sure it doesn't exceed 35C...

Found the link! There's a chart towards the end of the document. While not fool proof it can serve as a guideline to determine lumens/pupil lumens per watt when it's not specified by the manufacturer!

the chart is pretty usefull!thanks alot!
