We need your advice, I am sure it will help someone someday.

You are welcome Sara

I may be a novice at growing but have many, many years of building and technical experience so always willing to share my knowledge with the great community here

Thanks ganjazz,

Just put plants under under 96x3w led after 2 weeks pregrow under TL

Coverage could be better, cant get mush lower.

Planning and waiting now for another 96x5w to get better coverage

 

[ganjazz]

Thanks i think its sufficient for now, but not when room get filled more in couple weeks, i want place 2 opposite direction and get them closer to the plants.

When available in UK 96x5w ,can you let me know?

 

[Mars Hydro]

No worry ganjazz, I will post here when the 96x3w one has upgrated to 5watt ones, I am sure it won't be too long. But please note the coverage is the same, only penetration is better and more powerful

Yesterday I got a mail that Germany doesn't have the 100x3W mail and that they have to ship from UK (or if I want the 60x5W).
I mailed back that I want the 100x3W but I haven't received a message back.

Should I have said my ordernumber with it or do I have to wait a little?
Edit:resend the email

Hi Hydro... Sara won't be back on here until about 8pm eastern USA time... but I would advise to resend the email and add your order #....

Nice to see you Happyjoy, you can hang the light around 24inches, if your plants don't reject the light, you can hang it closer, but no less than 18inches Remenber more cal and mag there, also ph 6~6.5

1)do you think i need to add cal-mag even though im using biobizz organic nutes?
if so, should i add already from now, or just wait and see how they deal with the lights first?

2)is it most optimal to run both switches (bloom and veg) on the reflector series, evem though im just in veg?
i know the purpose of the switches is to save electricty, but if i dont care about that in this case, is it best to have them both on? or will it cause more stretching?

 

[Dennise]

Hi Happy... I run both the reflector series and the Mars II's..... I have found with the reflectors.... if electricity is not an issue.... does veg a bit better with both switches... but it does a fine job with just the veg switch if utilities are a concern... I have run full grows both ways and now always have both switches on... I do heavy training with my girls so I really can't answer the stretch question as I keep my girls pretty low as rule but I don't think you would get much more stretch IMO... As far as adding the cal/mag.. I would start with 1/2 tsp per gallon now and if you see any issues increase it to 1 tsp per gallon of Ph'd water...

High HydroDyna, we are now also improving our old models to 5watt ones, lol The 3watt ones in Germany is out of stock now, so only 60x5w available, much the same, only a little smaller on the size. If you want the 100x3w one, we will have to ship them to you from UK. Hope this is clear.

Good Evening Sara.

 

[Mars Hydro]

Good day Happyjoy, please add the cal and mag from now, as the plants under the LEDs are needing them badly.
As to the switches, you sure can turn both switches on, more power for the plants and they will grow quicker. I believe most growers also do that although in veg stage. lol

I personally would not even consider it an option but that is just my opinion and not worth a lot.. I honestly would go with out it before using that... If you are short the $10 or so just wait until you have it... If your girls are still in veg you should be fine and as far as that goes I have done complete grows without it but my grows with it are better........
