hps

Currently in week 2 of flower. I understand that it is possible to top up the light with CFL although would a dual spectrum have any negative effect. When i look at the CFL it is one slide blue one side red (obviously) but just wanted to know if this would have any negative effects for the...

i currently have 2 600W hps lights and 12 small super lemon cuttings was just wondering if I was to put a 24watt LED light in between the 2 lights would that make a difference on plant growth or plant quality? No experience what so ever with LEDS if someone could help would appreciate it

I use HPS for bloom. Problem is that my grow room gets too hot during the summer months. I have considered an AC unit but unfortunately it would add too many amps. So far, I have closed down the grow during the summer. My interest is focused on extracts. I make extracts of the entire harvest...

Ok sealed room with wall ac carbon filter 2 600w hps room size is 4x5x7.5. Runing co2 tank have the ball just barley spining in regulator should that be good or should i up it a bit

Okay okay okay, so I'm pretty new here, but I thought it would be a cool idea to create a new South African group so that all the South Africans (probably not that many) could discuss their grows including problems, successes and general questions. This group isn't solely for South Africans, but...

Hello people, i have a few grows under my belt and looking to maximize my 2x1.2x2 tent. Looking at a possibility of doing a scrog in canna coco pro with a+b and pk 13/4. Not had a grow in a while and no clones available so would be buying a 10 pack of feminised and taking a clone of the best of...

Hello everyone. The names MzanziMarijuana and I'm pretty new to growing. I've read threads all over RIU and live it. So much helpful info on here. I recently started a hydro grow (dwc) and experimenting with organic nutes to see how well I can grow and what issue i will run into. I have a...

Hello fellow tokers and growers everywhere. First off, I must state that I have been completely overwhelmed by the since of community on this forum and outright shocked at how willing the more experienced folks here on this site are to help the beginners. I myself am a beginner and am just...

hey, as i said im not sure how to connect my bulb to the 400w hps ballast, it has a weird output socket(pic below, bottom right plug). dunno if i need a reflector or what.

So I am a little over 2 months veg as of tomorrow and in need of opinions on weather, these girls are ready to bloom. If not maybe how many more days/weeks OH! Black indica is the strain

I was looking at the VIPARSPECTRA PAR600 600W 12-band LED Grow Light but have heard a lot of bad reviews about it for flowering... but also a lot of good reviews.. obviously i don't want to spend $250 on a light that i can only use for veg, someone here on the forum suggested i use this LED...

So i have a small grow tent 2ftx4ft with one plant, and im currently using 150 watt hps with 200 watt cfls on each side of the plant. Its to hot in the grow tent and cant give it much more venitlation due to its location besides the fans i have in it already. So should i just use the cfls next...

Just pricing out at the moment so any input would would helpful. Sooo basically 3X3' or possibly 4x4' grow tent, had my eyes on a couple LED panels such as viparspectra, Mars 600w or 2 300s due to energy savings but mainly thinking less heat and not possibly needing a bunch of duct fans ect...

Is this overkill or can it work?

Ok so this summer is going to suck. Like sweltering buy new acs and pray you don't have a heat stroke at work type of suck. I could go on but I digress. The particulars: temps 88 to 90 outside temp 96 to 99 6.5x3.75x7.5 1200w hps 1 magnetic 1 dimmable. 10" fan filter reduced to 6". Another 6"...

Came home and my MH was cracked and off. Not sure if i can get another right way. I have my 400 watt hps. Can I veg and flower on just that and that alone. Also what effects may I come upon using only hps as apposse to mh and hps ? Thanks

Anybody know how efficient they are? Comparing 2x 900 watt viparspectra leds to 600 watt hps.

So im only growing one plant and i have a 150 watt hps in my 2x2x4 grow tent. Im hoping its enough but id like it to have more than an oz. Should i add cfls? If so how many? Or is it good enough?

I was checking out some awesome outdoor grows from fellow RIU's for 2017 and decided we should show the same love for our indoor growers :) The outdoor thread: https://www.rollitup.org/t/open-show-and-tell-2017-18.934481/unread So to start it off, here is my current grow with pictures taken...
