That's not good about the shop lights, since the other day I bought a second one...Think a T5HO would be more consistent / accurate in Watts, or think we could even out the shop lights?
For gnat control.. have you tried Predator mites? https://www.planetnatural.com/product/fungus-gnat-predator-entomite-m/
Last year, my bag of Ocean Forest had some.
I use Ocean Forest bought from amazon for the last two years.. haven't had a gnat yet. For some of my desert plants that I used MG soil for.. I pour boiling water in the soil before use, and let it cool down overnight.
It is! I'm shocked by how much. I have the light 13 inches away. 16 hours on. That's the last time I buy a blurple. I definitely need to buy at least three more lights.
I had a Black Pearl last year that was root bound, and it looked a lot like that. Leaf loss, curled/ deformed leaves.. nothing I gave it helped until I looked at the roots.
LOL! Sorry.. Mil-spec stuff lying around. I do want to get one more though.. my store only had one.
I will let ya know how it works out.. I have a two month old Choc Primo, four month old Naglah, and a Lava Scorpion. I'll let you know how the light does with "older" plants.
For the...
Just bought one of these myself, and hung it up using 550 cord.
I found this looking for the specs: https://www.digikey.com/product-detail/en/everlight-electronics-co-ltd/EAHC2835WD4/1080-1460-1-ND/6002478
Not sure if these are in the lights.
Ugh, long day fog... Just remembered that I started to try out Blackstrap Molasses... it's unsulphured, and it has Magnesium, calcium, and some potassium... not sure it's enough for a plant though.
