Looks ok. Using bottom range 301b leds, kind of like spider farmer and mars hydro... Not tightly packed if I'm being honest. Would be good for a 3x3 - 4x4. I wish you luck in your future grows

Hps mixed with mars hydro 600 yield?
Hey all! So i been thinking about ways to cut heat of course lol. So I’m thinking about getting a mars hydro 600 and running it with my 400w hps at 250w on the dimmer. Do you guys think I will yield about the same as if I was just running the hps on super lumens?

Single CF Grow COB LED (300 W) sufficient for one plant?
Would like to know your thoughts on my 300-W COB LED (www.amazon.de/dp/B07Z678V5) I’m using in open space on a single plant. I’m not expecting huge yields with this lamp, but I am hoping it will be sufficient to bring a healthy plant to harvest.

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

Swapping lights during flowering
Do you guys think that swapping lights at the late flowering stage is going to harm my girls in any way? Been fortunate enough to be able to order myself a Viparspectra xs4000 to replace the v600. And as I understand it should be quite an upgrade. Thanks for any advice!

Growing lamp
Im currently using 45W florescent 6500k for the seedling stage. When do you think is the best time to start using the 400W HID with a Cool Tube and how far it should be from the plant?

Spider Farmer SF1000 or Mars Hydro TS1000?
What would you recommend between Spider SF1000 or Mars Hydro TS1000? Both seems pretty similar, which one to chose? I’m planning on growing two autos at a time/or one photo, 70x70cm space.

Ventilación y Luz en plantulas
Me inspiré en McGyver y he puesto un armario improvisado... Cómo de importante es la ventilación en esta etapa de plantula?🌬️ (He dejado la puerta entreabierta por las dudas)🤔 También he puesto otra luz auxiliar..se notará en el crecimiento o desperdicio luz?🔌🔋

Leaves "praying" after lowering the lamp
I am in week 4th of flowering Laughing Buddha, 220W LED ~60cm from tops. Today I have lowered the lamp and the leaves started "praying", on one (higher) plant the other, mostly-indica Holy Punch seems unaffected. I am curious, is there too much light or sweet spot and it's good?
