I recently switched from using a relatively inexpensive $150 1200 watt LED to a 400 watt Metal Halide/ HPS set-up.
For the second time in a row now it seems like my Plant(s) just want to keep growing and growing and growing and growing (you get the point) after switching from 18/6 to 12/12
I'll let the pictures do the talking as far as my grow set-up etc and I'll answer any questions you have later. I'm growing feminized photo-period white widow seeds from Nirv&^@ (AM I allowed to say?) I grew the same exact seeds with the LED with the same exact drip feed set-up and after 3 days I always saw white hairs every time like clockwork. I'm growing in a basement with a short ceiling so I only have 48" headroom from the growing medium to the 6 foot ceiling. That only gives me 30" for the plant + 18" minimum for the grow light. With the LED I started flowering at 22" and it was perfect. So I switch to a 400 watt MH/HPS set-up with a "wing" design vs a vented hood. My grow space has a 4" exhaust fan built into the wall and a wall mounted 12" oscillating fan. I know everyone is using tents now but I'm in a basement doing it the old school way I guess. I had no issues with the LED.
This time I wanted to make sure I had enough head room so I switched to the HPS bulb (red spectrum) and a 12/12 schedule on the 6th of May @10am when the light normally comes on I switched the bulbs and reprogrammed my digital timer to shut on/off at 10am/10pm (it was 10am/4am with the MH light)
Every single day since I switched bulbs/schedules my plant has grown 1" but I don't see any white hairs. This is now day 6 and my plant went from 14" to 20" I'm using old school general hydroponics flora series nutrients just like I always did before with the LED.
LASTLY... NOBODY but nobody disturbs my plants when they're sleeping. That room is pitch black! I used to develop film in that room in college (yeah I'm old) so no light gets in! Nobody accidentally turns lights on or shines a flashlight on my plants. Will the wrong HPS light / spectrum cause this? The last time I waited 13 days for 2 plants to flower. They hit 30" and I had to scrap them!! This is beyond aggravating. That's why this time I started flowering @ 14" (I can't recall the exact amount of vegging days) Like I said these are photo-period feminized White Widow plants. From the same exact batch I grew with the LED!
PS. Yesterday I switched from the "transition to bloom" mixture to the "Blooming" mixture.
PSS, Does it sometimes take 2 weeks for white hairs to show???
THANK-YOU!!!!!!!!!!
