If u got the money to burn go with a mh veg room and a hps room for flowering. If u want sum thing simple regular store bought cfls and make a light. you tube is a wonderful thing and theres not much differnts between soil and hydroponics. Its all personal perfrence. Hydro is a little bit...
im not sure what that stuff is but if you sprayed and it was sunny it could possibly be it but im not sure. maybe just cut the affected leafs off and see if it comes back.
ima first time pepper chilie grow ive grown many other thing just never pepper. i gor my first seed from from a friend but im not sure if there even gunna germ.
it depends on how u want it fruity or savory. im not really a big fan of carrots so i probably wouldn't add them. and ei probaly would only use a little bit of onion and garlic. fruity sweet hot sauce
a watermelon hot sauce would be interesting
lemon juice. garlic maybe a fruity white wine, butter, moruga peppers, strawberries.( kiwi would be cool) salt pepper. my mouth is watering. simmer and blend up, put through a stainer let it cool. damn i wanna make this now
