Hi,
90gallon, CO2, with 4x55W compact flourescent bulbs (AH Supply). Black Flourite. Plants coming in for new start up.
I plan on dosing 1/2 EI for the first 2 weeks, then switching to full EI. Lighting at full will be 8hr total, front bank on in AM, 2hr overlap with both banks on, then rear bank on for remainder day (front bank only -->2hr front+rear --> rear bank only: total photoperiod = 8hr)
Questions:
For new start up, what would be sensible lighting strategy. Or just start lights at full?
For new start up, 1/2 EI for first few weeks good?
Any recommends for iron dosing at start up?
My "full" EI below look about right?
Full EI means:
3/4 tsp KNO3, 3x
3/16 KH2PO4, 3x
15ml Tropica Trace, 3x
2 TBSP GH Booster, at water change
(lots of GH Booster, GH is normally 1 with nothing, and 1/2 TBSP GH Booster brings my 20gal GH up to about 5 [so .5 TBSP x 4 = 2 TBSP, approximating amount for 90gal])
thanks,
