I would not buy these. You would need a whole lot of them to amount to anything. Be better to buy a budget growlight off Amazon.

Should I use Blue light switch or Red light switch or both for vegetative growth?
I'm currently using a Giixer 1000W LED grow light. The lamp has two switches. One for "blue" light ay 450nm and one for "red" at 600-700nm. I am currently in week one of the vegetative stage. I have both switches on for "full spectrum" lighting. Blue or Red switch alone?

300w COB CREE Distance?
I've put my 6 seedlings under a 300W COB CREE UFO light, atm is a 30cm distance from them, I do hope is not too close. I've only a 140cm height and more would be problematic to manage in the long period.

Should one decrease light intensity during early flower?
Should one decrease light intensity during early flower, and then gradually increase again? I see DLI/PPFD recommendations for flowering in general, but not for the different stages of flowering.

Bad idea?
Will a mars hydro TS1000 be too strong for a 60x60x140cm tent? I have been using a TS600 and TS1000 in tandem in a tent 4x too big for the light level, I have been growing strong and tasty buds but with low yields so downsizing my tent size to maximise the light.

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

What’s the ideal amount of LED light for top quality in a 4x4 tent.
I’m exclusively looking to grow top end quality. Already can with HPS setup but wanting to switch. Is 480w Kingbrite LED quantum board with 385,660,730nm enough for this or do I need more? Any other suggestions? Aliexpress/Alibaba manufacturers preferred due to shipping costs.
