Thanks
@AeonSophia glad to have you here!
I've been using all the veg nutes but the BioMarine @ 2ml/L. Keeping it simple. Got tired of the smell (gagtastic) and oily residue it was leaving on pretty much everything. Should be switching from the veg. to bud as soon as they stop stretching.
For as cheap as these cobs were I've been pleased with them so far. They don't seem to be the most efficient lights. They make more heat than I was expecting, but not nearly as much as a hps bulb would. However, the proof will be in the yield after the chop. Not too concerned with max weight as I am with quality meds.
If your looking to add cobs take a hard look at the AFN lights that
@BigSm0 has been putting together. They are incredibly efficient for the money.
Do you have a journal? I'd love to follow along!
