Special Kush 3x3 Sea of Green

I'm spending lots of time just staring at my plants. They're growing so fast now. I'm adding root stimulator to the water and lower the PH level of the water to 6,5 with lemon juice. I read somewhere that using lemon juice is less effective on the long run than phosphoric acid. If anyone has more info about this, please leave a comment. Used iron spray on a weekly basis to keep the leaves green and healthy My Spectrabox Pro 4s light has a flux density of ~ 400 µmol s/m² and a max power consumption of 240 watts which I think is a bit small for my 90x90 cm tent. I researched for days and finally bought the Hans Panel 180w to accompany the other led. I'm loving this thing so far. For 250 euros you have a a panel with strictly high quality Cree diodes, a dimmer (great for germination and saving energy in early stage) and a bloom switch for extra red + deep red LEDs. The panels are developed by Hans himself, you can see mutiple test grows where pulls 1,2 from every watt here: http://www.ledgrow.eu/test19.php Total flux density is 1140 µmol s/m² now which is comparable to a 600watt HPS. My total power consumption in flowering will be: 240 watt led + 180 watt led + 15 watt exhaust fan + 5 w eco fan in room = 440 watt Compare this to a 600w hps setup: 600 watt HPS + 70 ballast + 60 watt powerfull exhaust fan + 10 fan = 740 watt total So the LED setup uses 63% of a HPS setup. This means less money spent on electricity, less fire hazard, longer lifespan of LED's, etc.
