During my IC absence I have been experimenting using only household led globes. Specifically
1 Utilitech WW RP (remote phosphor) @ 22w
1 Philips WW RP @ 17w
2 Utilitech WW SM (surface mount) @ 7w with globes removed
I replaced the 7w with CREE 9.5w WW
The original plan was to double the number of bulbs with the same bulbs, but the LED market is moving incredibly fast, and although I have very good results vegging 2 clones under this set up, I decided to change it up and go with 4ft LED tubes. Why?
For one thing, globes are point source - intensity falls quickly after ~ 10" which is why I planned to double up on them
Tubes provide an even spectrum balance across the entire canopy and can be positioned closer to the tops
I bought 2 Utilitech shop light fixtures (the T8 is sturdier than the T12!) and 4 iBright 4 ft @ 18w/ @ $35/, not bad when you consider I was paying ~ $30 per (including shipping for 54w aquarium HOT5s). Based on my last grow with globes + a R:B ufo 90, 23 w is not too dissimilar
Within 4 hours of adding them into the mix the plants responded, sending out a lot more pistils
Grow method is Bubbleponics, using 3G buckets with 2 efficient air stones per bucket. Air pump is 35LPM
I trimmed roots for awhile as I had let a few tap roots grow too long. Trimming caused more roots to develop from inside the net pots, BUT, I waited too long to begin trimming; it resulted in full size single blade leafs. Now getting 3 blade with newer leafs 5 blade
Nutes are Hydroponic Research V+B (thanks netprofit!)
Temp only increased 1 degree with 36 more watts, resting at 80 degrees
Plants were flipped from 14/10 to 12/12 on 6/6
No plans to add any blues or reds of any kind are planned. This thread/grow is all about "White Power"
