If you don't add CO2, that's a bit warm. Not sure on break-even with the extra light... depends on if you are near cap already for DLI -- see DLI chart in my profile comments. convert your lights umol/s per your area^2 to umol/s per m^2 and that's "ppfd" portion of table. DLI is found by hours you use the light per day.
But, if already near the cap sans CO2, no reason to add the heat.
if not...
What about on for 30mins, off for 30 mins? or 15m intervails.. in ratio to get any amount of extra hours worthwhile to get without damaging the plant.

You'll have better coverage with the two for sure.. Dial them down to control the temps imo! Happy growing! 👊

Which of the two options do you choose and why:
Option 1: 1440w over 40sqft giving 36w per sqft
Option 2: 1440w over 48sqft giving 30w per sqft.
The difference is an extra 2x4 of grow space. Do i go for more lumens or more plants? This is my first LED setupWeek 4

feeding great on a really low EC at 0.8, but i see other grows at pushing 1.5 at the same week. im flooding (Oxygen Pot w/ hydroton) every 4 hours, which feels pretty often. are the amount of floods proportionate to the EC? ex. if i flood less then my ec should be set higher?5 years ago

Light scheduleSo I got a new timer and messed up schedule. Plants got 16 hrs of light, turned lights out as soon as I noticed (5am).
11am-11pm light.(5 weeks into flower)
Should I let plants have 12hrs dark now and resume 12-12 , or let lights come on at 11am(6hrs dark)

Thoughts on providing enough nutrients in the soil for the plant to uptake as needed; rather than feeding while watering? According to Ed Rosenthal if you start with a rich enough medium, you don't have to feed. This is my current method, as I am still a noob. Gracias friends.Week 7

FloraCoco Grow instead of FloraGro in Hydroponics DWCIs it OK to grow in DWC Hydroponics using FloraCoco Grow (4-0-5 with also 0,8% of Magnesium) as one of the nutrients, combined with FloraBloom and FloraMicro? I'm asking because the store near home had finished FloraGro (3-1-7) and sold me FloraCoco Grow.Feeding. Schedule

Hi guys.
Considering the several problems of this grow, how I can change my setup for the next grows?
Now I'm using Plagron Alga fertilizers and the Promix substrate (no fertilized). Do you suggest to set the lamp in bloom mode (more reds) also during the veg phase?
Thanks,
M

I'm already seeing yellowing and on the largest plant, #3. Is that due to growth or am I over watering? Approximately 2 gallons in the wick bucket every few days when it starts to feel dry, but I generally spray the top with water on a daily basis, not more than a 1/4 - 1/2 cup.

Switching from seedling to veg feedingWhen should I switch from seedling to early veg feeding schedule. Im using General Hydroponics Flora trio in a DWC setup. I have read that a plant is no longer a Seedling once its new vegetation has the number of blades that the final leaf will have. Is this true?

Maximizing terpenesHow to maximize terpene production? I'm growing a strain that is supposed to be super stinky, and I so desperately want to get the full potential from this Chemdog cross. What does the plant need for producing terpenes and thiols? (My setup requires fully dissolved nutrients.)Week 9
