400w HPs Soil Blue Dream GSC Auto & Critical Kush Grow

Hi, new here but an older grower that just started back up after 10 years of not being able to grow. This is my 2nd grow. Last one was in summer and had a lot of problems like not getting the strain I had ordered, too many plants (10), mold, mildew, no fertz, heat problems and the dreaded spider mite infection, it wasn't as bad as I thought it would be but the quality was extremely diminished. Though the cookies were good we made from the cuttings.

OK so now that the wedding is over and it's colder I just started a GSC Auto of jan 7th & Just Planted a BF Critical Kush 15 mins ago. Planing on planting 3 HSO Blue Dream fem as soon as they arrive.

Set-up

Small fan

400w HPS bargain HTG supply version

Ok so heres some pics of the grow room

Any thoughts or advice?

Ceilings are 3 meter or 9ft high BTW

I've used that promix.. It's not bad but be careful if you're not using fabric or airpots.. It can hold water for awhile in regular pots. So watch for that and fungus gnats.

Oh yeah!
Good luck with your grow
