How To Use Progressive Web App aka PWA On 420 Magazine Forum

This is what I use
24 to 30" seedling
18 to 24" veg
12 to 18" flower
I have a 400 and a 900 Mars 2
A 700 will work well in a 3x3x6
I like to run 35 to 50w psf and power pulled from the wall with them.
a 700 pulls 307w from the wall that puts it about 34w psf and that should work fine.
It will be a little weak at the edges in flower.
But should give you a good 30x30" core footprint for flower.
May i know that do you have grow journal?
I can not do that because of where I live. It would not be safe or smart to do.
Maybe one day I will be able too...
I am on day 42 of veg and I am using a Mars II 700
I just moved from 24" to 30" as the tips of the new growth which stick above canopy are starting to get light burn.
Hi ,Growers and suppliers .
Anyone else use their Mars 2 700 combo with HID or another brand of led ... or cfl ??
At the moment I use a M 2 700 with a digital ballast 600w with SL and 600 of course and 400-250 w , usually I use 400w 2/3 of time 1/3 600. This in an area of 16 square foots or 1,5 m2 . And 18-36 w of uv a and b ,t5 . grow in coco.
Before I used a a time was spider cob but the ones between mars 700 and spider grow very fast and then light bleached ( In flower minimum 20+ inch ,55-60 cm )not good at all small harvest .. and some bad taste..
this box I use as a bloom box 10-13 hours light / 24h.
A small one for clones and veg to small need bigger of all ...
when your plants got light burn,did you move some light out? And did you raise the light?
