p.s par meter in my opinion is essential to hit high numbers since the luxmeter is useless

Hi.... I cultivated for about 13 years with 600 watts hps with good results 1gpw 0.9 gpw. for about 2 years I switched to LED DIY Cob, Quantum Board etc. initially the results were better than the HPS but not the stratospheric numbers as I saw on the forums, the temperature and certainly the...

how many HLG-240H-C1400B drivers can I put on each channel? 1-10v

600-800 watt cob is ok for best result in 4x4 if you want more efficiency samsung strip or board 350-450 watt for my experience

ok thanks..... I will try these bags if I find them in Europe

if in doubt, ask me if I can help you .... how many plants do you have?

soil is easy to grow ph 6-6.5 ec 0.6-2.3 4x4 100-150 liter of soil 4 or 6 big pots or 20 - 40 smallpots for 4x4 area if you wash by hand it is very easy not to let the water out of the pots and wait for it to dry to flood again 7 liter pot max water 1.5 liter for a day but 0.5 -1 liter is...

first week of flowering air temp 27 c leaf temp 24-25 c RH 60%-75% atacalmag (0.5 ml for liter )0.1-1 ml for liter is the range par 650 ph 6.2 ec 1.2 soil no red stems in the last round no calmag and I had the red stems...... same condition

no I don't grow in a tent. in the coming months I will study a good solution for low temperatures and co2 I just hope not to increase the rh too much.... if I have to use a deomidifier for a few kw then all the efficiency goes wrong

perhaps the simplest solution for me is a gas co2 generator(waterheater : ) .... it will produce heat and I can manage it automatically.....

I wanted to put them on gas heaters too, but I'm still not sure how to install them. there are manual ones without an outlet pipe but they do a lot of light .... then there are the automatic ones with the chimney .... how did you do it?

so you had 740 watts of citizen in 4x4 .... hydro or soil? sog or scrog?
