Cobs on or off 2nd week. 1st grow

Qpalzmstarted grow question 3 years ago

Cob lights. I can only run one light with cob on without the room getting to hot. Am I better with 1 light with cob or 2 without cob on. Philizon 3000w cobs. 20 11 day old plants. Hanging 24" atm. Mainly blue red without cob on.

I would run the cob and get an extraction fan to pull out the heat at the top and fresh air in at the bottom. An inkbird temperature controler really helps here.

Bend Her Over?Any chance of super cropping a thriving auto on day 42? She hasn’t flinched at training yet; and got hacked on. I’m running out of vertical space with some developing runners. She’s going to stretch a bit yet, and currently 12” from light with 650 PPFD. Bend, or not to bend?

Hi first time grower here. Been vegging 4 plants in 80cmx80x160 tent with 150W LED (Mars Hydro TS1000). Start of 2nd week flower today and I added another 150W LED. Could that potentially increase my yield? Thanks!
