Hey Guys, I live in a country where it's hard to order things in. Before I had been ordering cal-mag but recently our local customs grabbed each shipment claiming some bullshit that I must have an agricultural license to import. At my grow room I have a deep well. When I did my first grow I...

Hey Guys, I'm building a top feed system for 6" grodan blocks. I have the floraflex tops to use for top feeding. Can anyone recommend what tube size to use and the best way to make this? i.e. Can I buy a ready made manifold that has, say 8 outlets for the tubes? Or is it easier to make one...

Hi Guys, I'm setting up a new system. It's a rockwool top feed system on a large table. I'll be using double stacked 6" grodan cubes with a floraflex top feed system. I'm trying to work out the best way to feed them. I can fit an 800L tank underneath the table and then recirculate the...

Hey Guys, We're about to build a new grow room and looking for options. The only downside is we're growing in a tropical country where outside temps average 97F all year round... Our new grow room will feature multiple aircons where we can maintain any temperature between 70F and 86F. The...

Hey Everyone, I built a drain to waste system stupidly thinking it would work well if I used the biggest big mama grodan cubes and just top fed nutes on to it now and again. It worked well for the first month but now is a total mess. I'm thinking of nuking the whole thing and rebuild a newer...

Hey Guys, Just a quick one. I live in the tropics and its impossible to get nutes here locally. The only nutes I can get are Hesi liquid one part and they're posted from Holland. They take about 2-3 weeks to arrive and will often sit in the local post offices in 40+(c) degree heat. I've...

Hey... hey... Just wondering if anyone has ever used something like this to measure run off. I was thinking of installing one on the main pipe flooding my system and then on one the pipe exiting the drain tray going to waste. I can then measure the difference for each flood. I run a...

Morning Everyone, How's everyone doing? I can't believe I missed this sub-forum, so now I'm finally posting in the correct place! Sorry for the huge story... I made a post yesterday crying because I hadn't got my setup right. It's here if anyone wants to look. It's here...

Hey Guys, This such a great forum and I've had a lot of great help, I've built what I thought was a great system but looks like I'm having nutrient issues. I'm running drain to waste and I know 100% that my pH is perfectly dialed in (between 5.8-6.2) I know my room temp, RH / VPD, C02 and...

Hey Guys, I made a little time-lapse video of the growth so far, just wondering what you think? I think it's incredible to see actual growth by the hour. Does anyone know why the plants flop down a few hours before lights out? I thought it might be lack of water, but tried watering them...

Guys, Maybe I'm over thinking things and sorry if I ask too many questions - I'm learning. I have built a top feed system which is drain to waste. I'm using big mama cubes. I'm wondering how often to feed the plants. The drain to waste works well, when I feed, water flows freely out from...

I'm not having much fun learning how to grow, I think I bleached my plants with my new HLG 550V2. I'm running two of these bad boys with a secret jardin dr240w tent (120cm*240cm*200) Not only was my EC meter reading under by 0.2 (So I nute burned them, now I've blasted them with too much...

Hey Guys, I'm having some weird issues, or maybe it's me? I thought bluelab was the best equipment out there, so I bought myself a couple of pH dosers and some guardians.... Now the first issue I had was with my first guardian which I'd been using for about 2 years. I noticed my new plants...

Hey Guys, How's it going? I recently dumped my hydroton flood and drain system and turned it in to a rockwool top-feed drain to waste with big mama cubes. It's going really well, the growth I've had in 2 weeks has been incredible. I planted these seeds direct in to the cubes on 26th...

Hey Everyone, Just a quick question about the dreaded root rot and the best way to avoid it. I'm running a drain to waste rockwool top feed system. The reservoir I'm using is filled from an RO system. I'm running C02 so the room temperature is 28. However I'm running chillers on the...

Hey Everyone, I'm about to do a new grow and got sick and tired of cleaning hydroton. I just want something I can grow in and throw away, then start the next grow. I'm trying to keep it simple and easy. I decided on modifying my flood and drain system to use the large big mama rockwool cubes...

Hey Guys, Can anyone advise me? I'm not sure what I've done wrong. A couple of these two week old northern light seedlings are showing issues, the others are OK. They're all in the same environment with same nutes, etc. I'm not sure why some are ok, but others not? At the moment I'm hand...

Guys, just checking this will work, can't see why not.... I'm running flood and drain buckets with hydroton. I've had enough of dealing with hydroton, it's a mess, it's a pain in the arse to clean. I just want something I can use and throw away. I always start my babies in small rockwool...

Hey Everyone, I'm just trying to work out what to do about future grows, whether to go with a mother plant and clones, or stick with seeds. To be honest, adding another tent, light and hydroponic system for a mother plant would be a pain in the ass (but do-able...) Originally I was using...
