Thanks for the reply Chris….yes both those photos are of tops & you’re right there’s virtually no ambers atm. My girls always seem to run a week or 2 over & I’m fairly sure it’s because I’m only running a sf1000 (100w). Ive stopped feeding them now & the gorgeous colours are just bursting thru, we’ve also had a bit of a cold snap here for the last week so that could’ve helped to bring the purple hues out. I’ve just had another look prior to sending this & the 1st ambers are just starting to appear…woo hoo
