Good to leave any light you have, but I would recommend placing you HPS horizontally for max light to the canopy. Cheers

Sure leave them. Just don't break them they have mercury in them. Toxic stuff.

Light stress during the night time
Question to outdoor growers. The auto flowering plant is growing in the garden, and sometimes there is light on during night time, can it cause light stress? It's usual light bulb, 40w, in some distance

LED light recommendation
I am going to need a new LED light to hang from the ceiling. I am looking for a light that has the red/blue spectrum. A dimmer switch would be awesome- the ones I read about that include-seedling, veg and flowering settings sound amazing. Any recommendations out there? Thanks in

Can rotating my 12 hour cycle back a few hours over the course of 3 nights harm my plant mid flower?
If i were to manually flip my lights on and off an hour early for 3 nights to adjust my 12/12 from 9am-9pm to 6am-6pm would it be detrimental to the plants? They are in the 5th week of flower. Rotating back 1 hour each night

Growing out instead of up.
Please help out! I moved it into a new pot and topped it last week as suggested. Also new ViparSpectra light at 45cm away @80% power. Nutrients/food yet to arrive. It seems to just be growing out instead of up, and starting to see some white/ burnt looking spots. Suggestions?

Anyone affiliated with Mars Hydro? Very disappointed with customer service
My TS 1000’s controller/driver crapped the bed. Contacted customer support, told them the issue, they diagnosed based on videos i send, and was told they were sending replacement parts. 2 weeks later, no email confirmation and no reply to my previous 2 emails sent a week apart.

Right lighting at day 6 - fluo or HI as both available
Right lighting at day 6? Very happy that all germination looking good on day 6 from seed. I could either continue with this compact fluorescent bulb (15 cm from tiny first leaf) for another week or two OR switch to full HI 250w immediately (30cm from plant) Thanks!

Colour lighting
Thanks to eveyone that replied to my last question, really means a lot! Another quick question about lighting I had was if I should have blue light for veg then red for flower or just have the mixed purple on for the duration of the plants life?

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

Light Burn? Mars Hydro TS3000 at 30% Power, 26 inches away per manual. I have since raised back to 30 inches.
Is this light burn? I noticed some slight yellowing/crispy looking leaf at day 11. Light is about 30% Power, about 30 inches away. I previously had it about 26 inches and raised when I noticed this issue about 24 hrs ago. Pics are updated. Temps: 70-75 RH: 50-60 Soil Runoff: 6.5

Grams per watt
What’s the best gm per watt that someone here has gotten on a single plant? I’m aiming for 1gm per watt but doubt that she will yield 315gm once dried.

LIGHT SPECTRUM, is that a good one for growing cannabis?
Hi guys, in the future I plan to upgrade from the current 2x2 box/150w LED. I was thinking of a 4x4 area with 500w LED. I came across an interesting 500w led lamp for quality/price and this is the spectrum chart, does it seem suitable for growing cannabis?
