Have someone used thermostat as heat fuse? I have an idea to place it before my timers and lights and switch it to about 95F or something. If the temp will be lower than that thermostat will let power through but if there will be some problems with fans and temp will get too high it will switch...

Hey, Could You please help me with this. I want to connect fan with dimmer - no problem here. Then I want to connect same fan with termostat. The idea is that I turn dimmer halfway but if temps are getting to high the termostat turns it to full power. Is that possible? And is there any way...

How far from plant are those day time CFLs? You can lower them without hurting the plant as they are not hot at all. I have seen when they even touch the leaves without burning them. It will double lumens! Those lights will be not enough for budding. I suggest You plan on buying more watt CFL or...

Any ideas how high plants should be when entering flower phase to fit in 60cms. Will SCROG be necesary?

Thanks for reply. I think You misunderstood something! Plant for itself has a 65cm space for height and lighst have to cover 50 x 80cm so it fits Your suggestions. Or am i missing something?

This is more like a micro grow project. If I will put in lights with more watt it will lead to high temperature and more costs on vent system leading to higher noise leading to fail the project :) My point is to use scrog if plants will not have enough height but I will not leave them for long...

Just made my setup for growing mother in soil and clones till buds in hydroponics (airoponics) Venting system includes: 1. computer fan for mother and clone chamber (think that will be enough because have CFL bulb in there if not another fan can be added. 2.10x10cm fan with dimmer for seed...

I have just put them in pot! they sprouted yesterday. Man in Amsterdam grow shop sweared that they are good. Sprouted next day I put them in water. I will update when it comes out.

I am keeping pH from 5.8 to 6.1 so this is not the case!

So? Did it help you?

Everything looks fine. Leaves are back healthy lifting up and good color. I think those salts helped a bit. Yourlocal420 thank you I did calibrate my pH meter when the problem started because that was first what came in to my mind...

I found salt NaCl - 43% Potassium Cl - 42% Manganese salts - 15% and left my plant with 2 tea spoons this mixture. This will be good experiment :D. EC was up to 1.7 :O I will have a chance to look at them tomorrow. Will keep you up to date.

Best I could find: NaCl - 43% Potassium Cl - 42% Manganese salts - 15% Is it OK? I have 5gal so 5 table spoons? Those fan leave stems are red! Is it normal?

Is it Mg deficiency? This is White Widow Using nutrients: https://www.rollitup.org/dwc-bubbleponics/187122-those-nutrients-ok-veg.html Also using Hydrogen peroxide 50% 9ml to 5gal 300w HPS lights 18h/6h ventilation OK. Inside temp 68f-75f(20c-24c) Anyone had this problem? I know...

I think results are showing now: Is it Mg?

Thanks for helpin out, How much should I add it to my solution? I have around 5-6 gal. If my tap water has 200ppm does it mean it has Mg in it already? Or is there a chance that it could be?

Where could I get just Mg? I did big research in my country to find nutrients like this which are +/- good for growing. Others re very low on Nitrogen... Any suggestions?

I am using nutrients: 1. N-P-K 7-3-6 (+S 1.8) N 7% (NO3-N 3.3%; NH4-N 3.7%) P 3% (P2O5 3%) K 6% (K2O 6%) S 1.8% B 0.01% Cu 0.002% (EDTA) Fe 0.05% (EDTA) Mn 0.02 (EDTA) Mo 0.001% (EDTA) Zn 0.002% (EDTA) 2. Calcium +N NO3-N 1.8% Ca 2.2% Are those OK or I need something...

Take clones from mother plants on veg not on flowering stage!!! And keep them on veg till you want to start flowering. Rate me if it helped ;)

Post nutrient solution label. You should use something like N-P-K = 30-10-10 for vegetative stage. Are you using air-pump with air-stone? I would suggest! For 2 1/2 week old plant 500ppm should be max in my opinion... If your pH is OK then its too much nutrients or salts are dense in root...
