When to put the light on?
Panzora
started grow question 5y ago
Hey there, Do you need to put the light on the pots directly after you planted the seeds in the ground? Or do you need to wait untill they poke true the ground and then put the light on them?

Plant can't absorb light till leaves open. But I leave the lights on anyway because I don't mind paying my electricity bill.

KingBright 240w Meanwell driver relocation
Does anyone know the name of this connector the Kingbright LED boards use and where to buy them? I'm looking to relocate my LED driver but Kingbright wont be able to get me one till August. If I could at least find compatible adapters I can make my own cable out of them.

OK to switch from 12/12 to 18/6 for auto in flower?
Is it OK to switch an auto from 12/12 to 18/6 when in flower (2 weeks)? I moved the plants from the attic which was way too hot and tried the 12/12 schedule to reduce the heat. Now that they are in an AC spare room wondering if it would be worth switching. Appreciate the support!

Is 500 ppfd on new seedlings ok?
My light dimmer only lowers to 500 ppfd. I’m starting autoflower seedlings in a space tote before I move them into my perpetual harvest tent. I’m currently propping the light on its side so that the indirect light only hits around 300-400, as an attempt to reduce light bleaching.

light dilemma
When 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.

Good T5HO flower combo, 3000K and PureBloom? http://www.growagromax.com/products/t5-grow-lamps/t5-pure-series/agromax-pure-bloom-t5-high-output-grow-lamp/
Thanks to all for your great advice! This is my first grow, currently in veg wk 5, using 8 x 6500K, 4’ T5HO. Flipping to flower in 2-3 wks, will use 4 x 3000K tubes and planning to get 4 AgroMax Pure Bloom tubes. Is 50/50 mix of 3000K and Pure Bloom a good combination of light?
