Shes 33 days old and getting fed twice a day..1 litre at a time with around 12 hours between feeds.. the problem now is that shes about to stretch and looking at the growth under those big fans she may well want to squeeze the Grape Crinkle out of the way..

Tomorrow I'll be hooking the Mars light up again and trying to get it on their app and dialled in at a level that the plants can handle.. I need to get temps up a few degrees all round.. im hoping I can do that with the light as when I had it in last time that was the problem.. high temps low rh.. messed up vpd.. so if I can find the sweet spot on the dimmer I reckon I can use that to my advantage bringing my temps up.. rh down and vpd into the range i want.. which is the ultimate goal at this point.
This wee ac infinity box has already proved its worth.. so for anyone wanting to take a closer look at their conditions its an amazing tool for monitoring.. and the info it gives you for the very small outlay by 'grow shit' prices is top drawer. I cant recommend it highly enough.

Now.. im off to open those vents i closed earlier.. I hoped they lift temps.. but rh has gone up instead.. way too high for my liking.
