Ideally you would want to space them so there is a bit of overlap in the footprint . . . perhaps one 90W LED for each 2×2 square for a hobby grow or one 180w LED for a professional grow. Can you get away with less, absolutely . . . but this configuration is optimum with our lights and generally yields 30-50% more over comparable HPS (600w and 1000W respectively).

Minimum for this space would be 3 x 180w LEDs for a solid grow.

*****90w Illuminator VS Mother Keeper . . .
Really important!
The 90w Illuminator is a GROW LIGHT whereas the Mother Keeper is NOT!
The 90w and higher are designed for growing from veg to flowering . . .
The mother keeper is only designed to keep your mother plants healthy while promoting branching sites for future clones.
The mother keeper will not work if used alone from seedling – you need a 90W or above.

I’m also setting up a grow tent for the first time and was wondering what LED option would you suggest for a space 6ft x 4ft and 6ft high? I’m also curious about what is the difference between the illuminator ufo 90w and the motherkeeper, as they are both 90w and use 1w LED’s, as i am on a budget and there is a reasonable price difference between the two.

Thanks

Q1 – Yes, they can be shipped to the UK, discrete packaging. I would HIGHLY recommend staying away from Ebay . . . check out this post on 225 led grow lights to find out why.

Q2 – For a PROFESSIONAL grow, go with 4x180w LED lights for each 4×4 square – this should get you a 30-50% increase over a 1000W HPS. As a hobbyist, you can do quite well with 4x90W LED lights for the same 4×4 square and still match or exceed the yield of a 600W HPS. Just multiply for your available growing footprint.

**Can you have a good grow with less??? YES, it just depends on how many plants you have in each 4×4 section and the canopy thickness . . .

Q3 – Check out the offerings from Stealth Hydroponics, they can hook you up.

Q4 – If you are using soil and ESPECIALLY if you are growing hydroponically, you need clean water . . . invest a bit in a reverse osmosis water filtration system to ensure a pure source of water for your plants.

Q1 can you get them in the uk i.e the light you are recomending NOT EBAY if poss

Q2 8×4 tent what light/lights would you recomend
4×4 tent just in case
id prob grow as tall as poss aprox 8 plants far max smelly -”

Q3 can you recomend any carben fillters far the 8×4 and 4×4 tents

Q4 as this is led what else would i need /light, tent, fan, carben fillter,fertilser feed

£$£$£$£$£ is a prob but if it worth it ill save a littel longer

What I would do is break down what you want to grow into 4×4 foot sections to make it easier. Then for each section you would grow 5 plants. Now, for a hobbyist grow, each 4×4 section would use 4x90w LEDs while for a professional/industrial grow you would use 4x180W LEDs. Testing has shown that using this formula with our lights can get you a 30-50% increase in yield over the equivalent HPS light in each section (600W to 1000W respectively).

So all together, by following this equation, you would use 4 lights per section and have a total of 10 – 4×4 sections to accommodate all 50 plants.

Thanks

Can you first tell me how big your plants will be (height/width) on average when ready? Have to make sure there is enough space for your plants first, then determine how many lights you need.

Thanks,
