If you have LED light, you definately should increase the light level to 400 ppfd! 150 is much to low.

150μmol/m².s is very low to me. You can start increasing gradually to reach 400μmol/m².s

Looking at your pics I'd say the light height is decent where your at.

What are you checking with? How does the plant look? What's the light manufacturers recommendation?

I’m here again with another silly question Or not I’m not sure🤣 I have a 600w ballast with a 600&400 switch on it and I’m wanting to downgrade to a 250w lamp. Will my ballast power it okay or will it kill it🤔 or should I get a 400? Thanks!

What’s up guys me again😂 I’ve got my hps up and running and I’ve got the temperature under control by having my fan blowing directly at the light and I’ve added a oscillating tower fan. How can I keep the temps up when lights go off? Many thanks!

Wich of those cheap lights would be advised under 200€ and that would fit both final vegging state and flowering? The grow space is 80cmx80cmx160cm and keeping in mind that the weather along with the lack of ventilation budget limits my options to colder leds. Thanks in advance

Too close to the “sun”(light).... any advice?
My plant grew close to 4x it’s original size during her stretch, 10-12” on day one of 12/12 to 46” tall. She’s on day 30 of flower and I set up a second ScrOG net. Other than blocking light to shorter plants, do you see any other potential problems this second net might cause?

Light upgrade.
I m thinking of moving away from my mars 144 to the mars ts1000 mainly for white light over pink. Is the ts1000 a good light and worth it. Compared to the mars 144?

Nanners?
Can someone verify my latest 2 photos look like nanners? If so, I’d love some insight on why my plants seem to be so light sensitive. Most growers seem to blast their plants with upwards of 200w with little issue. Mine is sitting at 80w 22inches and it seems to be struggling!

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

Cloning area lighting
I have a 4x4 tent that has 2 plants growing, and 1/4 of it I wanna create a little box that light cant get out if for clones to grow, and set an LED in there. If I take clones, set my main plants to flower, takes 4-6 weeks, how much light is needed for the clones to survive?

Anyone have any history with vibrating HPS lamps? Mine keeps making a buzzing/rattling noise. I’m thinking it’s the metal inside rattling on the glass so if I slightly rotate it it may stop? What do you think? Thanks!

600w hps
Wouldnt 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?
