started grow question 6y ago
What ppfd do you guys recommend for plants in veg? I’m finding that my light can be too strong at max power even at a 24” distance.

Put your hand under the light at the height of your canopy., if your hand feels comfortable under the light for 1 minute then your girls will be fine. Cheers

Change light schedule
My babies are now in 8wks, the light schedule is 17:7. I have scheduled the 8hrs sleep frm 5am-12pm (this is my sleep time) and now that I hve changed my sleep time, I would like to change their sleep time too, from 10pm to 5am. How will I change the light without stressing them?

Schould i buy another more expensive lamp with more watts or can i just buy a second xs 1500 ?
Does it make sense to buy another Viperspectra xs1500 with 150watts? So my question is, if the power of 2 same led lamps add up together?

Best Light Schedule for Autoflowers?
I'm wondering what light schedules my fellow growers like to use with their Autoflowers? I'm debating weather the additional cost of a 20/4 is worth it in terms of growth and increased Bud Quality/Size over a 18/6 schedule. I would love to hear your experiences.

Temperature VS More Light which is better for buds size and potency
Should I continue to use two LEDS if temps are reaching 87f during flower (day 1) or just move plants more towards center of tent and use one LED for better temperatures (75f) (only growing two plants). lights are 1000w bestiva and are in a tent that is 24"x48"60".

switching lights from veg to flower.
Hi. Ive seen a lot of growers leave there lights on 24hrs or 18/6. Ive always switched mine to 12/12 when switching to Flowering. Has anybody noticed a difference when leaving lights on 24hr or 18/6 instead of 12/12. Thanks.
