hey just recently switched to a recirculating setup, supposed to be a bit faster and better yields that pots. well i've had alot of problems since the switch and i'm thinking about canning one of my new setups to go back to pots. one of my systems is an ebb/flow or flood drain table, the other is a three pot top fed type. i'm not having much luck with either as the plants are growing slowly and poorly. i'm going thru nute changes and clean water flushes once per wek. ph is stable now at 6.3-6.6. i'm even using co2 in the flood drain table. there is one exception though, i went and used two varietys for the flood table, afi#1 and g13 and g13xhp. probalbly a bad idea i…

Beating the Summer Heat By Erik Biksa During the heat of the summer many gardeners growing under lights shut down and wait for cooler days. Typically H.I.D (high intensity discharge) lights produce nearly as much heat as they do light, with the exception of some of the newer electronic HID lighting systems. Because they are usually operating in a closed environment, the heat radiated quickly builds up the growing area. If temperatures exceed 85° F in the plant canopy, results are usually diminished. Most grow rooms have an exhaust system to evacuate hot air from the growing environment. The system usually uses a larger CFM fan to pull air out of the growing …

Hi all, I have 3 seedlings under flouro's about 4-6 inches away, They are 16 days old in perlite/vermiculite. They look like they are dying, The leaves are going off colour, They are getting lighter and then heading towards yellow/brown. This is starting from the tips of the leaves heading in, Fast. 2 were transplanted recently and have had their first drink of 1/4 strength nutes, This prob started before the transplant and nutes but the nutes seemed to speed things up. The 2 first round leaves are the healthiest looking, They aint effected. Could this be overwatering, I water from the bottom so the cups sit in a couple mills of water most of the time. Any help or advice …

Does anyone know what may have caused this and how to get rid of them.......thanx guys you all rock

Does anyone have any advice for acclimatising plants growing in less than ideal outdoor conditions to much happier, much higher light conditions indoors? They're under a 400whps, one in a bubbler and the other in a mixed media of perlite/expanded clay/growool floc. The light has been raised to 45cm from the tops because of current spraying with white oil, but I'm worried the lighting could cause some probs. Or will any light scorch or any other problems be restricted to the outdoor growth, with the new shoots being produced being already used to the environment? Any advice appreciated.

I just had a look at my plants and the yellowing seems to be getting worse! They are in week 3 of flower and are 3 1/2 months old in total. I have been told that the shade leaves do yellow and die of slightly in flower and this is expected with sativa dominant plants but the yellowing seems to be working its way up to the leaves on the same nodes as the buds!! I am feeding them with 1/2 strength fish ferts (N) and full strength potash (K) (P) with added Mg. Buster.

The plant is 6 to 8 weeks into flower. The buds are all still white hairs, there's no more than 5 redish hairs on the whole plant, so this tells me that it's only in the middle stages of flower. The prob is, all the big fan leaves, from the bottom to the top of the plant are going yellow.. at a very quick rate. Only thing i can think of is it's been starving and it's starting to eat it's self. It's on a slow drip system in dirt so i soaked it today for the first time in a few weeks, hoping it'll come back to good health.

I killed them all by squashing them and sprayed all 4 clones with neem, how often should i use neem?? also on the plastic around the small rockwool cubes there is what looks like mould? what conditions are wrong in my setup?? too much water? too much humidity? too much heat? these clones have not rooted visually yet, and have been taken a week ago, how long would i expect to wait. i have a fishtank lined with white/black plastic, is is air tight and vented a few times a day, (well its a snake cage with sliding doors the whole front of the tank ope…
