Spider COB LED

Okay, this is 3rd week of bloom. I can fast track this diary because I'm actually at week 8 of bloom and starting flush so I will put them up as I get time. In my last dairy I got a really good bud structure using my custom spectrum 36w par lights for veg and start of bloom, but spindly buds, I think from over water, because the roots in the 50l pots went straight down to the air stones I have in the bottom of the pots. This time around I dropped the water from 1-3 litres a 50l pot to 0.2-0.3 litres a 15l pot. The buds are diffidently a lot denser. Normally my co2 bottle only uses 1/8 of a bottle for the whole run but unfortunately in the last week of veg I had the 450w leds on and the power went out coursing the co2 controller to fail and it used about 2/3 of a bottle in 3 days before I realised. the plants grew about 10-15cm but really spaced out nodes and lanky stems in the end smaller buds. So I don't think I got conclusive results in my change of watering experiment with Purple LEDS .
