Light distance and intensity concerns, TS 1000

Mr_Incognitostarted grow question 3 years ago

Guys, anyone with Mars TS 1000 or similar? Is it ok to put light at 50 cm only 50% power on week 4 from seed? Pre-flowers are showing very slowly.

Download a phone app called photone. Check your ppfd you should be around 300ppfd and 20DLi for the stage your at. Then use the app to monitor what ppfd/DLi your plants like at various stages of growth and then next time you'll find it a lot easier to judge.

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 setup

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

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!

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?

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

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!

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!
