Yup. Hammer them things! About 3” for seedlings is good to start.
Need advice / opinions - 2 400 watt hps vs 600w hps in 4x4 tent

I keep a t5 about 6" or even less from seedlings as long as I can keep the temp no higher then around 78°. Once they're hardened off I keep the t5 as close as I can without the plant being closer than about a half inch by the time I adjust the light at the end of each day.[/QUOTE]
Hmmm if the leds are hard to dial in mayne ill try the t5 again . This is COMPLETELY off topic . But maybe you have some knowledge regarding Blueberry kush strain. Read that blueberry doesent usually need much nutes. Just alot of calmag. I was feeding lightly. FFOF soil. 5 ml of general organics bloom and 2.5ml of bio bud with some molasses and 5mg calmag every third watering . Showed calmag def still and began losing its green color fast. So I doubled doses every third watering . Showed some improvement . But still hungry. I now am feeding 10ml of bloom . 5ml bio bud. And 5ml calmag and do 2 feeding in a row and water with just water on the 3rd watering. It's just now starting to really take off on bud growth. Zero nute burn. Wasnt locked out from Ph. I just couldn't believe how hungry she gets. Even the smallest plant ive ever flowered. Only 18 -24 inches tall

Yep, really any more than about 3" and some strains will get a bit stretchy before they harden off. I put 6" out there as a safe compromise in case of warm rooms.

I've got the 4 ft 8 bulb t5 fixture . How many of the t5s should I have on ? 5,000 lumens per bulb..2 bulbs maybe ?

If they're like the ones I have where you can run the 4 on the inside or the 2 on both sides I'd run the 4. If they don't cover everything then run the full fixture.

The 4’ is a bit overkill but yeah, run the 4 bulbs. I have 1 18” and 1 24” over a 10x20 seed tray for my seedlings. Ill take them to like 6 or 7 nodes under that then move them to my main veg area.
