geeze, not wrong bud, they literally ripped him a new a new @sshole!!
I had a hand at lettuce, outside no matter what i tried, they kept getting eaten. Slugs down here are packing ak47's and have iron guts. Inside under lights its was too strong, considering it was a communal planting with other veg. So no, i cant really give you first hand account of what worked for me, as ive hand limited success & decided buying it for $1 at the shops was ok...lol
I did research ways to get around it though, firstly there are types that are more resistant or go through blooming later.
Secondly, cutting down the total light helps, outside a higher ratio shade cloth can help based o your situation. And for captive systems, decreasing the nutrient temps can assist also. So abit of trail and error id say. However like i said, i gave it away.
Good to see your fish though bud, i'll confess though, 9min of the same shot is abit rich, i wouldn't even stare at my own privates in the mirror for that long
From the filtration stand point, yes its meant to be an 'on-par' ratio, so 1:1.
However you have raft system with no media apart of that ratio, so yeah, its logically higher.
However its only a guide, the real question is whats your actual tests showing?
