20 hours, how many seconds in 20 hours? 60x60x20=72,000s Ppfd x 72,000s will give you the exact micro moles. You want 40 dli? 40,000,000Ă·72000= 555.555 the recise ppfd to use to reach 40moles in 1 daylight cycle.

The max DLI you want to put on autoflowers is 44 without CO2. You can experiment with that number but that will get great results.

I'd say between 30-40 Dli. Sometimes they will take the top end of that scale Sometimes the lower end. Start at 30 and see how they react.

Do I keep dimming my light to try to get proper DLI?
Currently at 22" above soil at 50% intensity and still getting ~50DLI at Germ/Seedling stage (too high?). It's a 240W LED. Do I keep dimming the light or do I change light schedule (24h currently) to get proper DLI?

Starting photos indoors for June transplant
Want to start photos on a 14/10 schedule in April to match the lights around June 1st. Can I grow my babies on a 14/10 indoor schedule or could that possibly induce early flowering? I would rather not slowly adjust down from 18 to 14 before Xplant as suggested otherwise

LED lights for veg-Viparspectra xs1000
I have the viparspectra xs1000 light. I turned up to 50% intensity and plant is about 30cm from canopy. Is that right for early vegetation stage?It looks healthy to me but could be wrong. Was going to turn up to 75% later, then 100% for flower. Do I need to move closer the light?

Hight Problems
Iâve got 3 plants in my tent, but theyâre all different heights. To compensate, Iâve hung my light at an angle, so one end is closer to the smaller plants. My question is: Does this help, or am I better off keeping the light level? Any tips for dealing with uneven plant heights?

amount of sunshine for autos in late flower - open air, outdoor grow
We're getting 14-15 hours of strong sunshine a day. Now that I'm late flower, should I move my autos into a spot that will get shade for half of the day? Seems like they may not need to be pounded by this much light/heat at this point and could use more down time.

Do I need to lower my lights?
Do I need to lower my lights? I'm using a Kingbrite 240W Samsung lm301h and I just went into flowering period. I think the light is a bit overpowered for the room, so I've left it at about 21 inches above the tops of the plant. At this distance, all areas are getting 27k lux.

How can I reduce the heat in my 5x5 tent (650w light bar/6" ac Infinity and a ton of fans) without AC? Do I have to leave tent open?
5x5 tent is in a kind of lung room (utility room) that stays around 20C/68F. The tent always seems to be at 30C86F with lights on. Ive added and moved fans, opened more intake vents. I have AC, but its -25C/-13F outside. Id like to drop the daytime temp 5ish degrees for flower.

Are 2x 150 watt lamps as good as one 300 watt lamp? I am thinking about upgrading to 300 watts, I already have a Mars Hydro TS1000 with 150 watts. (in 80x80cm / 2.625x2.625ft.) Thanks for your recommendations growmiesđ
