When to turn the light on after sprouting?
WeedDoctorSamstarted grow question 4 years ago
We have a sprout! Tropicana Banana sprouted between 10pm last night and noon today. Can I turn the light on now, and start the 18-6 schedule tonight or will it fuck it up if I turn the light back off at midnight tonight to begin the 18-6 schedule?

Yup as soon as they are "sprouted" they are ready for light.. 24-0..18-6...20-4.. You choose the veg schedule.. as long as it's more then 12 hours of light she will not go into flower.. All the light schedules are for is to simulate the changing of the season.. so when you flip to 12-12 in a couple months the plant "feels" that autumn or fall is coming so it flowers..

13 hours on.. 11 off is close enough that some strains of cannabis will flower under 13-11. some might even flower at 14-10.. But you get the idea..

Bad idea?Will a mars hydro TS1000 be too strong for a 60x60x140cm tent?
I have been using a TS600 and TS1000 in tandem in a tent 4x too big for the light level, I have been growing strong and tasty buds but with low yields so downsizing my tent size to maximise the light.Other. General questions

Lighting cycle for VEG stage. Is 24x7 OK?Hi,
Should I use the VEG lights 24x7 from the time I plant my seed until it's ready to bloom, or would something like 18 hours on and 6 hours off make more sense? Is there a "best practice" for veg lighting? It has worked for my first 3 grows. VIPARSPECTRA 600W LED
Thanks,

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

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)

Grow lightsI'm currently looking for a new grow light. But it's crazy how many choices there are. Since my grow area is very small, 40x40cm or 1x1', I don't need a lot of wattage.
So would prefer to invest in quality over quantity. Any suggestions?Week 11
