Throw out one plant?
Is it productive to kill one plant if the rest of the plants are filling out the room just fine and to promote ventilation and light penetration? I have one plant that is way shorter and behind the others due to genetic problems.

Hi guys! What light should I get? The viparspectra xs1000 or the marshydro ts1000? I intend to grow in a 2x2 space. Would the viparspectra be as bright as the marshydro because its more efficient?

600w hps
Wouldnt let me PM. I have a 5ft long 3ft wide 6ft tall white walled grow room and am thinking about a 600w HPS light now. Will this fill the entire room? If so how many plants should I plant? Will this one suffice? Would a 400w hps be more suitable for this space?

amount of sunshine for autos in late flower - open air, outdoor grow
We're getting 14-15 hours of strong sunshine a day. Now that I'm late flower, should I move my autos into a spot that will get shade for half of the day? Seems like they may not need to be pounded by this much light/heat at this point and could use more down time.

Is that possible to do grow light with Samsung LED strips?
Going deeper into idea of doing the quantum board from scratch but instead SMD LED's there are lots of strip LED options. So I want to ask you guys if I have an aluminum plate with a heat sink and coolers, can I fix those stripts there? Or can I rip them off with a heat gun?

Light burn
2 fairly new leaves at top (opposite ends) seem to show signs of light burn (yellow tips). They recently turned a bit more green but the tips are still quite yellow. Light = 13 inches away. PAR 370 at center, 350 on sides. DLI=~ 22.5. CO2 bag in tent (at about 620). Thoughts?

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

Back To 24 Hour Light - Auto Flowers
My autos switched from 24 hour light to 16 about 2 weeks ago to see if it would help make them bloom faster. Can I turn them back onto 24 hours or could that mess things up? I would like the most amount of light time. They should have 2 more weeks left
