Took the plunge and got some cobs.
I pay 0.13 per kilowatt hour.
Vegged for 3 weeks 24/0 under 100 watts, 0.32 per day. 6.50
Vegged for 2 weeks 24/0 under 200 watts, 0.64 per day. 8.96
Total running cost of lights =15.46
200 watt dimmable light bar cost 200ish (parts cheap from kingbrite)
215.46
Under 600w MH would have cost 65.52 to run.
I know cfl, t5s, etc could be more efficient/cheaper, but basing it on a 600w MH for veg.
Cheapest dimmable digital lighting system 85 + 65.53
140
light bar expectancy 50,000 hours
MH bulb 5,000 - 20,000 hours. Cheapest bulb costs about 20
HPS bulb about 20 per bulb
Going for a quality system you an double these figures easily
To replace the cobs on the bar would be expensive but chips are getting cheaper, if I could start again I would buy a cheaper cob but just went with what I'd read from Supra and Growmau5. I'd also mix the kelvins, I don't know a lot about the sciencey stuff, 3500k was recommended as a good all round spectrum. From what I've seen there's something lacking in flower which prevents donkey dick buds. Just my opinion based on absolutely nothing.
I'm not advocating COBs yet, I'm hoping for the best but I'll be completely objective and prepared to sell the lights if they don't perform!
Made a few fk ups during veg, plants got very stressed a few times. Trying to adjust to new systems, different heat/humidity, trying bubble buckets. Was originally going to try capn style buckets but think Ill hand water rockwool since I'll need to hand water the coco/hydroton mix. Might still automate it, see how it goes.
4 x critical +2.0 clones in bubble buckets. About 5 weeks since cut. Some topping. Super cropped early. 1.2 ec
2 x Black D.O.G. Coco/hydroton mix. Trasplanted once, will transplant into 35 litre fabric pots. From seed about 6 weeks old. Both topped twice. 1.2 ec. Theyr'e thirsty so watering every day atm, mix doesnt hold much water.
2 x Incredible bulk from seed. In rockwool, will be and watered in rockwool the whole grow. 0.4 ec.
GH Gro 3. Micro 2. Bloom 1
SIlica 1ml per litre (also PH up)
Cal Mag .8 ml per litre
Rhizotonic, varying amounts depending on need, roughly .5 ml per litre
Cannazym, varying amounts, 1 ml per litre when I see any brown on roots
22-24 Celsius
60ish humidity. Ambient is about 45, I lay wet towels and pillows around the tent to raise it.
PH adjusted to 5.8, runoff in coco is usually about 6.1.
8" oscilating fan not directly on plants, leafs all trembling. Used a dremel to bur holes in the front and back of the base so I could hang it with bungees.
12" Mountain Air filter
10" Phresh Hyper fan silent, connected to filter with a plant pot.

Bit droopy, transplant shock and establishing roots, just put in buckets
