Cheers bud,

Turns out the reflector inside the cool tube had slipped round a bit so I think I have to agree, I've also reduced flow to co2 to the bottom shelf.

Will the bottom shelf catch up, harvest later or just be a bit stunted? Size wise they are all the same but bud development looks at least a week behind?
StickyFingersAgain Reviewed by StickyFingersAgain on . Puzzled... Can anyone explain why? Started to flower all the plants at the same time. They all went on 12-12 and I have noticed on the top shelf the flowers are a good week if not more in front of the bottom shelf. Can anyone offer an explanation. 1-The only contributing factors I can think of is the inlet fan is positioned at the bottom but the air is temp controlled so shouldn't be shocking them. 2-The cool tube has sucked a bit of dust into the glass housing and it needs a bit of a clean- could this be the reason?
