Ac infinity pro 69

[Hdk40]

Hi to all! Ok…3 blueberry matics in germination (one popped can see tap root, waiting on two more fingers crossed) Anyway, just about to set the ac infinity controller to the right temps/humidity etc. What do you set everything at for just planted seedlings? I don’t want to ruin these. I also have the ac infinity humidifier/exhaust fan/small standard fan and ducting. Also, do we need a CO2 bag at the seedling stage?

TIA - HDK

There are lots of ideas but you need a system not some answers to this question and some other answers to the next. If you can't find a good grow diary for your exact strains then I'd follow the generic advice given in the upper left menu.

No CO². 21⁰C 80%RH on first leaves, 100% prior. Slowly increase temps to peak at around flip stage (26 to 28⁰C) and slowly lower humidity for around 60% at flip. Keep night time temps 2 to 4⁰C lower.
On flip slowly lower temps to around 23 to 24⁰C mid flower and continue to lower RH to low 40's. If pushing the last 2 weeks with monster buds aim for 30%RH but must be able to not let temps climb.
CO² bags make little difference but if running CO² enriched environment say 1500ppm then increase lighting by 50% and temps above 32⁰C ideally....too hard if you ask me for a up to 20% yoeld increase
