4 hours is not enough to really effect anything. Now a day other 2 and it is different story. You will be fine. Relax and enjoy the grow🌱🌱🌱👍

Bro, 4 hours of darkness will not hurt anything. Complete the light cycle as usual and improve temporarily aeration. No worries

Lights. Please explain to a newbieHow much light does a seedling need? How many watts? Is it better to have one bulb but closer to a plant, or 4 bulbs and higher from a plant?
Does it matter how many plants are under the light if they don't shade each other? Do plants "steal" rays so its better to have 1 plant?Setup. Lighting

I am thinking of eather the LIGHTWAVE T5HO 60 CM (48W) or
MarsHydro TS 600 (100W)

600w hpsWouldnt let me PM. I have a 5ft long 3ft wide 6ft tall white walled grow room and am thinking about a 600w HPS light now. Will this fill the entire room? If so how many plants should I plant? Will this one suffice? Would a 400w hps be more suitable for this space?Setup. Lighting

I purchased two Vipar Spectra 300 LED Lights. I am only using one right now because i was concerned two would be too much for the seedling phase. Should I keep just the one light or Put up Both ? When would be a good point in the plants life cycle to put up the extra lights ?Week 2

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

light dilemmaWhen shine only with flower light, i reach 20,000 lux units in the buds area. But when i turn both lights on at once, both the growth and bloom spectre, the lux units increase to 65,000. I wonder if the extra growth light will affect the flowers that are already blooming. Thanks.Setup. Lighting

Marshydro ts600 for a 50x50x100Hi quick question,
Purchasing 50x50x100 tent
Will the marshydro ts600 be ideal for this yes just shy of 2x2.
Im aware the ts1000 is better and has dimmable option but wouldn't that be too powerful for my little 2x2 with a height if only 100cm? Will be from (marshydroled.co.uk)Setup. Lighting
